Description

  The present invention relates to, for example, a telephone system in which a plurality of telephone terminals are connected to a so-called main apparatus in a facility such as a company and can record a call voice.

  Conventionally, various telephone terminals having a function of recording call voice have been provided. For example, in Patent Document 1 described later, in a voice communication system connected to a PBX (Private Branch eXchange) or a public network, recorded data can be recorded by performing key input or mouse operation on a necessary portion during recording of a call voice. An invention has been disclosed in which a mark can be inserted into the data to improve data retrieval efficiency. The voice communication system is connected to a PBX or a public network and includes a voice input unit that is a microphone / speaker or a handset, and thus corresponds to a telephone terminal. It is configured to be performed.

JP 09-098212 A

  Generally, a business phone system (button telephone system) is constructed by connecting a plurality of telephone terminals to a so-called main apparatus such as a PBX or a SIP (Session Initiation Protocol) server. When each of the telephone terminals connected to the main apparatus has a call voice recording function, the call voice is recorded at the telephone terminal to which the communication line is connected. For this reason, when a call is put on hold / transferred, the call voice before transfer and the call voice after transfer are recorded in different telephone terminals. Therefore, when the user of the telephone terminal after the transfer wants to listen to the call voice before the transfer, it is troublesome to go to the telephone terminal before the transfer and listen to the recorded call voice. is there.

  In addition, in the business phone system, for example, one telephone terminal on the outside line and two telephone terminals on the extension line can be connected at the same time with each of three or more telephone terminals to make a call at the same time. Some have a so-called conference call function. When using such a conference call function, it is not efficient to record the call voice at each extension telephone terminal because the same call voice is recorded twice. In addition, even in case of hold / transfer or when using the conference call function, it is possible to easily search for the target location when listening to the recorded call voice later. Therefore, it is convenient if a mark can be added.

  In this case, for the recorded call voice, each user of each telephone terminal can add a mark to the part of the call voice intended by the user, and the playback position is determined based on the added mark. If the search is not possible, an efficient search of the playback position cannot be performed. Also, not only during recording, but also during playback, a mark is added to the intended location of the user of each telephone terminal, and the added mark is deleted during playback. It is more convenient if you can. In particular, it is more convenient for the user of the transfer destination telephone terminal to add a mark later to the call voice before transfer for the call voice when the call is put on hold / transferred.

  Further, when a mark is added to the recorded call voice, so-called cueing of the target location according to the mark can be easily performed, as described in Patent Document 1 described above. However, the content part that you really want to listen to is to look for the sound that is played. In this case, the content part you want to listen to is searched while fast-forwarding and fast-rewinding as necessary, but the mark position used for cueing the recorded call voice is lost and you are away from the content part you want to listen to. It is considered that there may be a problem that even if the position is reproduced, the user is not aware.

  In view of the above, the present invention appropriately records a call voice and adds and uses a search mark for the recorded call voice in a telephone system including a main device and a plurality of telephone terminals. The aim is to be able to do it.

In order to solve the above-mentioned problem, the telephone system according to the first aspect of the present invention provides:
A telephone system configured by connecting a plurality of telephone terminals to a main apparatus connected to a network,
The main unit is
Call voice recording means for recording call voice data in the voice storage means for each call;
The telephone terminal connected to the main device performs a call by connecting a communication line through the main device, and the call voice recording means records the call voice data in the call in the voice storage means.

The telephone terminal connected to the main device is:
Provided in the own device when a call is made by connecting a communication line through the main unit, and the call voice recording unit records the call voice data in the main unit in the voice storage unit in the main unit When a predetermined operation button is operated, operation information providing means for forming the operation information indicating that the operation button has been operated and providing the operation information to the main apparatus is provided.

  According to the telephone system of the first aspect of the present invention, the telephone system is configured by connecting a plurality of telephone terminals to a main apparatus connected to a network. The main device includes call voice recording means and has a function of recording call voice data in the voice storage means for each call. In the case where the telephone terminal connected to the main apparatus performs a call by connecting the communication line through the main apparatus, and the call voice recording means records the call voice data in the main apparatus in the voice storage means in the main apparatus. The operation information providing means can function. The operation information providing means forms operation information indicating that the operation button has been operated and provides it to the main apparatus when a predetermined operation button provided on the telephone terminal is operated.

  Then, the operation information provided from the telephone terminal that is making a call to the main device is received through the receiving unit of the main device. When the operation information from the telephone terminal is received through the receiving unit, the operation information recording unit of the main device functions. In this case, the operation information recording means of the main device records time point information indicating the time point when the operation button of the telephone terminal for the call voice data to be recorded is operated for each telephone terminal that has transmitted the operation information. Is recorded in the operation information storage means in association with the call voice data. That is, the call voice data is recorded in the voice storage means of the main device for each call. Further, the time point information indicating the time point when the predetermined operation button of the telephone terminal used for the call is operated is associated with the call voice data to be recorded for each transmission source telephone terminal, and the operation information of the main device Recorded in storage means.

  Here, the call unit refers to a period from when an incoming call or outgoing call occurs and a communication line is connected to when the communication line is released. Therefore, even if the hold / transfer is performed, the connected communication line is not released, so the unit of the call is not changed, and the call voice data after the transfer continues continuously after the call voice data before the transfer ( Recorded as a series of call voice data). Similarly, even in a state where a so-called conference call function is used and calls are made simultaneously by three or more parties, the connected communication line is not released. It is recorded as call voice data for one call unit.

  The time point information indicating the time point when a predetermined operation button of the telephone terminal is operated is associated with the call voice data to be recorded, and corresponds to a so-called search mark (separation mark) for the call voice data. . Moreover, time point information, which is a search mark associated with the call voice data to be recorded, is stored for each telephone terminal on which a predetermined operation button is operated. For this reason, regardless of whether hold / transfer is performed or the conference call function is used, the user of the telephone terminal can use the telephone call data to be recorded as a search mark for each telephone terminal. Time point information can be added.

  As a result, even in a telephone system configured by connecting a plurality of telephone terminals to a main apparatus connected to a network, it is possible to appropriately record call voice data and assign search marks to the call voice data. Can be done.

[Outline of the telephone system of the embodiment]
FIG. 1 is a diagram for explaining the outline of the telephone system of this embodiment. As shown in FIG. 1, the telephone system of this embodiment includes a plurality of telephone terminals 3 (1), 3 (2), 3 (3), a main device 1 through a LAN (Local Area Network) 2. 3 (4), 3 (5)... Are connected.

  As shown in FIG. 1, the main device 1 is connected to the IP network 6 and the telephone network 7 and performs address resolution between terminals connected to a communication path (communication line). That is, the main device 1 has a function as a small-sized exchange that connects the outside line and the extension line or between the extension lines. In addition, the main device 1 of this embodiment uses SIP (Session Initiation Protocol) to perform call control such as associating a telephone number with an IP (Internet Protocol) address or calling and connecting a partner. It also has a server function.

  That is, the main apparatus 1 of this embodiment also has a registrar server function and a proxy server function. By using these functions, the main device 1 can communicate with devices in the telephone system connected to the LAN 2, devices connected to the LAN 2, devices connected to the IP network 6 and the telephone network 7, and the like. A communication line (communication path) can be connected between the two.

  The IP network 6 means a network that performs communication using IP (Internet Protocol), and is specifically the Internet. The telephone network 7 includes an analog public switched telephone network (PSTN (Public Switched Telephone Network)), a digital circuit network (ISDN (Integrated Services Digital Network)), a cellular phone network, and the like.

  Each of the telephone terminals 3 (1), 3 (2), 3 (3), 3 (4), 3 (5),... Has a plurality of operation keys used by the user to make a call. . Each of the telephone terminals 3 (1), 3 (2), 3 (3), 3 (4), 3 (5),... Is in the same office connected to the LAN 2 through the main device 1 as described above. This is used when a call is made with another telephone terminal or with an external telephone terminal connected to the IP network 6 or the telephone network 7.

  The button telephone system of this embodiment has a call voice recording function. Provided in the telephone terminals 3 (1), 3 (2), 3 (3),... When talking through the telephone terminals 3 (1), 3 (2), 3 (3),. It is assumed that the “record button” is pressed. In this case, a notification that the “record button” has been operated is sent to the main apparatus 1, and the call voice between the telephone terminal on which the “record button” has been operated and the other party of the call is converted into digital data. The formed call voice data is recorded on a predetermined recording medium of the main apparatus 1.

  Also, automatic recording of call voice can be performed under the control of the main apparatus 1. For example, when one of the telephone terminals 3 (1), 3 (2),... Connected to the main device 1 responds to an incoming call to the telephone system and starts a call, the call voice is automatically recorded. Can be done. Further, when a call is started by making a call from any of the telephone terminals 3 (1), 3 (2),... Connected to the main apparatus 1, it is possible to automatically record a call voice. Of course, call voice can be automatically recorded both when a call is started in response to an incoming call to the own system and when a call is started in response to a call from the own system.

  In addition, when a call is started in response to an incoming call from a specific source, call voice can be automatically recorded. In this case, the telephone number of the caller to be recorded for the call voice is registered in a predetermined recording medium of the main device 1, and the registered telephone number is compared with the telephone number notified from the caller. This can be achieved. In addition, when a call is started in response to an incoming call having a destination whose telephone number is registered in a so-called telephone directory created on a predetermined recording medium of the main apparatus 1, a call voice is automatically generated. Can be recorded. On the other hand, when a call is started in response to an incoming call with a destination whose telephone number is not registered in a telephone directory created in a predetermined recording medium of the main apparatus 1, the call voice is automatically set. You can also make a recording.

  In addition, when a predetermined telephone terminal connected to the main apparatus 1 responds to an incoming call to the telephone system and starts a call, the call voice can be automatically recorded. In addition, the telephone system may have a plurality of telephone numbers. For example, a major representative telephone number, a representative telephone number for each department, a telephone number for inquiries from customers, and the like. In such a case, for example, when a call is started in response to an incoming call to a predetermined telephone number such as a telephone number for inquiry from a customer, the call voice is automatically recorded. it can.

  Thus, in the telephone system of this embodiment, the call voice recording function can be used in various ways. When the call voice recording function is used, when a predetermined operation key is operated through the telephone terminal that is making a call, a search mark (separation mark) is recorded for the call voice recorded in the main device 1. ) Can be added. By adding this search mark, when the recorded call voice data was played back, the playback position was quickly positioned at the position where the search mark was added, and recording was performed from the position where the search mark was added. Call voice data can be played back.

  In addition, when a search mark is added to a plurality of different positions of the recorded call voice, the jump is sequentially made to the position indicated by the search mark located before or after the playback position, and the jump destination is set to the playback position. It can be. As a result, the intended call content portion can be quickly searched from the recorded call voice, and the call voice of the call content portion can be reproduced and listened to. When the recorded call voice is reproduced, the position of the search mark used for positioning the reproduction position in the call voice is displayed in detail on the display of the telephone terminal described later. Thus, the reproduction position of the recorded call voice can be appropriately recognized without losing sight of the position of the search mark used for positioning the reproduction position.

Further, as shown in FIG. 1, the telephone system according to this embodiment has a plurality of telephone terminals 3 (1), 3 for the main apparatus 1 connected to the IP network 6 and the telephone network 7 which are wide area networks. (2) are connected. For this reason, in the telephone system of this embodiment, hold / transfer is often performed, and a conference call function may be used. Holding / forwarding is a state in which the connection destination telephone terminal is not specified (holding state) while maintaining the connection state of the connected communication line, and thereafter, the telephone is different from the telephone terminal that was the connection destination immediately before. This means that a terminal can make a call by taking over the communication line. The conference call function is, for example,
A communication line is connected between each of three or more telephone terminals, such as one telephone terminal for an external line and two telephone terminals for an internal line, to enable simultaneous calls.

  As described above, in the telephone system of this embodiment, the connected communication lines are not released (disconnected), and the telephone terminals used for the call may change or increase. Then, when the call voice recording function is used, it is assumed that a series of call voices to be recorded are marked for retrieval through the respective telephone terminals before and after holding / transfer. In this case, the search marks added according to the intentions of the users of the telephone terminals are mixed, and the function as the search marks is impaired. Further, when the call voice recording function is used, a series of recorded call voices are searched for through each of a plurality of telephone terminals using the conference call function connected to the main device 1. The same thing happens when a mark is added.

  For this reason, the main device 1 of the telephone system of this embodiment manages search marks for each of the telephone terminals 3 (1), 3 (2),... Connected to the main device 1. Then, each of the telephone terminals 3 (1), 3 (2),... Connected to the main device 1 was recorded using a search mark added through the own device when the recorded call voice was reproduced. It is possible to search the playback position of the call voice. Further, in the telephone system of this embodiment, a search mark is additionally added to the recorded call voice for each telephone terminal connected to the main apparatus 1 even when the recorded call voice is played back. , This can be managed for each telephone terminal.

  In this embodiment, each of the telephone terminals 3 (1), 3 (2), 3 (3),... Connected to the main device 1 is configured in the same manner. Therefore, hereinafter, the telephone terminals 3 (1), 3 (2), 3 (3),... Are collectively referred to as a telephone terminal 3, unless otherwise specified. Hereinafter, each device constituting the key telephone system of this embodiment will be described in detail.

[Configuration example of telephone terminal 3]
First, the telephone terminal 3 that is directly operated by the user will be described. FIG. 2 is a block diagram for explaining a configuration example of the telephone terminal 3 of the telephone system according to this embodiment, and FIG. 3 is an external view of the telephone terminal 3.

Furthermore, a “record button” and a “play button” are provided on the lower side of the numeric keypad and the like, which are used to use a call voice recording function and a reproducing function realized in cooperation with the main apparatus. The details of the call voice recording function and playback function will be described later.

[Action when incoming]
The packet data transmitted via the LAN 2 is supplied to the LAN I / F 302 through the LAN connection terminal 301, converted into data in a format that can be processed by the own machine, and then transmitted via the CPU bus 324. It is supplied to the packet processing unit 303. The packet processing unit 303 decomposes and extracts control data and audio data included in the supplied packet data. The control data extracted here is supplied to the control unit 320 and used for controlling the own device. If voice data addressed to the own device (own terminal) is included, the voice data is supplied to the call voice input / output I / F 304 through the CPU bus 324.

  When the control data decomposed and extracted by the packet processing unit 303 is a call message to the own device, the control unit 320 controls the ringer 315 to ring the incoming call. At the same time, the control unit 320 controls the display controller 313 to display a message for notifying that there is an incoming call, a telephone number or name of the caller, or an extension number of the caller on the display screen of the display 314.

  When the user lifts the handset 306 from the main body of the telephone terminal 3 in response to an incoming call to the own apparatus, the telephone terminal 3 enters an off-hook state. In this case, the control unit 320 forms a message responding to the incoming call, packetizes it in the packet processing unit 303, and supplies it to the LAN I / F 302. The LAN I / F 302 converts the packet data into packet data for transmission, sends it to the LAN 2 through the LAN connection terminal 301, and transmits it to the call destination terminal.

  As a result, a communication path is generated between the caller and a call is started. In this case, the packet including the voice data from the other party is supplied to the packet processing unit 303 through the LAN connection terminal 301 and the LAN I / F 302 as described above. The packet processing unit 303 disassembles a packet from the other party, and supplies control data to the control unit 320 and voice data to the call voice input / output I / F 304.

  The call voice input / output I / F 304 forms an analog voice signal to be supplied to the speaker (handset) of the handset 306 of the own device from the voice data from the packet processing unit 303, and sends this to the speaker of the handset 306 through the handset connection terminal 305. Supply. Thereby, the voice of the other party transmitted from the other party is emitted from the speaker (handset) of the handset 306.

  On the other hand, the voice collected by the microphone (transmitter) of the handset 306 is converted into an electrical signal here and supplied to the call voice input / output I / F 304 through the handset connection terminal 305. The call voice input / output I / F 304 performs processing such as converting voice data from the handset 306 into a digital signal, and supplies this to the packet processing unit 303. The packet processing unit 303 forms a packet for transmission to the other party including the voice data from the call voice input / output I / F 304, and sends the packet to the LAN 2 through the LAN I / F 302 and the LAN connection terminal 301. Send first. In this way, the telephone terminal 3 can respond to an incoming call to itself and generate a communication path with the call destination to make a call.

[Operation when calling]
Next, processing when making a call from the telephone terminal 3 (when making a call (calling)) will be described. When making a call from the telephone terminal 3, first, the handset 306 is lifted from the main body of the telephone terminal 3 to place the telephone terminal 3 in an off-hook state, and the telephone number or extension number of the communication partner is entered through the operation input unit 311. input. In addition, for example, by selecting a target destination from the phone book data of the phone book formed in the main device 1, it is possible to specify a destination to make a call. Information such as the telephone number of the other party input or specified here is supplied to the control unit 320 through the operation input I / F 312.

  Then, the control unit 320 forms a call message and supplies it to the packet processing unit 303. The packet processing unit 303 packetizes a call message from its own device, sends it to the LAN 2 through the LAN I / F 302 and the LAN connection terminal 301, and transmits it to the destination of the intended communication.

  After this, a communication path is generated when a response from the intended destination is returned. As a result, a call can be made by a call function including the LAN connection terminal 301, the LAN I / F 302, the packet processing unit 303, the call voice input / output I / F 304, the handset connection terminal 305, and the handset 306. As described above, the telephone terminal 3 can also make a call by calling the target terminal from its own device and connecting the communication line to the other party.

[Call voice recording function]
The button telephone system of this embodiment has a call voice recording function. The recording function is realized by the cooperation of the telephone terminal 3 and the main device 1. Here, the outline of the recording function and the role of the telephone terminal 3 will be described. In the button telephone system of this embodiment, the voice recording process itself is performed on the main device 1 side. Then, a call voice recording execution instruction or end instruction is provided from the control unit 320 of the telephone terminal 3 to the main apparatus 1 in response to a pressing operation of a “recording button” provided on the lower front side of the terminal.

  Further, the user of the telephone terminal 3 can add a search mark to the telephone conversation voice data to be recorded for each telephone terminal with a simple operation, and manage this for each telephone terminal on the main device 1 side. In this case, for example, the search mark added to the voice data of the call is added to the search mark added to the voice part uttered by the other party of the call and the voice part uttered by the user of the telephone terminal 3. A search mark can be distinguished and added.

  For this reason, a function for adding an additional mark to a voice portion uttered by the other party of the call is assigned to one predetermined operation key of the telephone terminal 3. In addition, a function for adding a search mark to a voice portion uttered by the user of the telephone terminal 3 is assigned to a predetermined other operation key. In this embodiment, the management of the assignment between the predetermined operation key and the predetermined function is performed on the main device 1 side.

  When the predetermined operation key is operated on the telephone terminal 3, the control unit 320 of the telephone terminal 3 provides operation key identification information corresponding to the operated operation key to the main device 1. Then, in the main device 1, according to the function assigned to the operated operation key, the time information indicating the time when the operation key is operated is associated with the recorded call voice data as a search mark. Manage each telephone terminal that has been operated. Here, as the predetermined operation key, for example, flexible keys FK1 to FK8 and a numeric keypad provided in the telephone terminal 3 can be used.

  In the telephone system of this embodiment, for example, several keys selected from the flexible keys FK1 to FK8 are used as operation keys for adding search marks. For example, the flexible key can associate the telephone number of the other party who frequently calls with the call function. For example, a function for adding an additional mark to the voice portion made by the other party of the call is assigned to the flexible key FK1. In addition, a function for adding a search mark to the voice portion uttered by the user of the telephone terminal 3 is assigned to the flexible key FK2. Furthermore, a function for adding a search mark to a voice portion uttered by another person is assigned to the flexible key FK3. The flexible key FK3 is used when the conference call function is used.

  Then, the user of the telephone terminal 3 responds to the incoming call or makes a call, and after connecting the communication line through the telephone terminal 3, the user presses the recording button to start recording the call voice. be able to. Thereafter, by pressing the flexible key FK1, an additional mark indicating that the voice part originated by the other party of the call can be added to the call voice data to be recorded. In addition, by pressing the flexible key FK2, a search mark indicating that it is a voice portion uttered by the user of the telephone terminal 3 can be added to the call voice data to be recorded.

  Further, when the conference call function is used, the flexible key FK3 can be pressed in addition to the flexible keys FK1 and FK2. When the flexible key FK3 is pressed, it is a voice part (voice part issued by a user of another telephone terminal) uttered by another party with respect to the call voice data to be recorded. A search mark can be added.

  As described above, when the user of the telephone terminal 3 is recording the call voice, the user can operate the flexible keys FK1, FK2, and FK3 to the speaker for the recorded call voice. A corresponding search mark can be added. As will be described in detail later, the search marks added to the call voice recorded through the telephone terminal 3 are operated by the flexible keys FK1, FK2, and FK3, which are operations for adding the search marks. Each telephone terminal is managed by the main device 1.

  As a result, when the user of each telephone terminal 3 reproduces and listens to the recorded call voice, the user can search for the desired reproduction location using only the search mark added through the telephone terminal 3. Yes. Usually, there are many cases where the user is almost determined for each telephone terminal 3, so that the user of the telephone terminal 3 can search for a playback location by using the search mark added by himself / herself. Of course, there may be a case where the call voice recorded when he / she is absent is reproduced and listened. Even in such a case, a search mark is added so that the voice part uttered by the other party of the call, the voice part uttered by the user of the telephone terminal 3, and the voice part uttered by the other party can be distinguished. Has been.

  For this reason, even when using a search mark attached by a user other than himself / herself, each of an audio part emitted by the other party of the call, an audio part issued by the user of the telephone terminal 3, and an audio part emitted by the other party It is possible to search for the playback position with distinction. Therefore, even when a search is performed using a search mark attached by another user, the playback position can be searched efficiently.

  In FIG. 2, the packet processing unit 303 is shown as an independent circuit part, but the present invention is not limited to this. Of course, the packet processing unit 303 can be realized as a function of the control unit 320 by a program executed by the control unit 320.

[Configuration Example of Main Device 1]
Next, the main device 1 to which one or more telephone terminals 3 are connected (accommodated) will be described. FIG. 4 is a block diagram for explaining a configuration example of the main apparatus 1 of this embodiment. As shown in FIG. 4, the main apparatus 1 includes a connection terminal 101 to the IP network 6, an IP network interface (hereinafter referred to as IP network I / F) 102, and a packet disassembly / generation unit 103. . The main apparatus 1 includes a telephone network interface (hereinafter referred to as telephone network I / F) 104, a connection terminal 105 to the telephone network 7, and a terminal management database (hereinafter referred to as terminal management DB) 106. ing. The main device 1 also includes a LAN I / F 107 and a connection terminal 108 to the LAN 2.

  Further, the main apparatus 1 includes a call voice file 109, an FK input file 110, and an FK setting data file 111. The main device 1 also includes a voice recording unit 112, an FK data management unit 113, a recorded data reproduction unit 114, and a control unit 120. Note that the characters “FK” in the FK input file 110, the FK setting data file 111, and the FK data management unit 113 are used as abbreviations for flexible keys.

[Basic components]
And the control part 120 controls each part of the main apparatus 1 of this embodiment, and as shown in FIG. 4, CPU121, ROM122, and RAM123 are connected through the CPU bus | bath 124, and are comprised. . Here, the CPU 121 executes a program stored in the ROM 122 to generate a control signal for controlling each unit and supply the control signal to each unit, or process information from each unit. The ROM 122 stores and holds various programs executed by the CPU 121 and various data necessary for processing.

  The RAM 123 is mainly used as a work area, such as temporarily storing intermediate results of processing. Although not shown, for example, a nonvolatile memory such as an EEPROM (Electrically Erasable and Programmable ROM) or a flash memory is provided, and data to be retained even when the power is turned off, for example, various setting parameters and functions are improved. You can also store and retain new programs that are provided for the purpose.

  The connection terminal 101 constitutes a connection end to the IP network 6. The IP network I / F 102 receives a packet supplied through the IP network 6, converts it into a packet in a format that can be processed by itself, and supplies the packet to the control unit 120. The IP network I / F 102 converts a packet to be transmitted supplied through the control unit 120 into a packet in a transmission format, and sends this to the IP network 6.

  The connection terminal 105 constitutes a connection end to the telephone network 7. The telephone network I / F 104 receives data supplied through the telephone network 7, converts the data into data in a format that can be processed by itself, and supplies the data to the control unit 120. Further, the telephone network I / F 104 converts data to be transmitted supplied through the control unit 120 into data in a transmission format, and transmits the data to the telephone network 7.

  The connection terminal 108 constitutes a connection end to the LAN 2. The LAN I / F 107 receives a packet supplied through the LAN 2, converts it into a packet in a format that can be processed by the own device, and supplies the packet to the control unit 120. Further, the LAN I / F 107 converts a packet to be transmitted supplied through the control unit 120 into a packet in a transmission format, and transmits the packet to the LAN 2.

  The packet decomposition / generation unit 103 performs packet decomposition and generation. Specifically, a packet to be transmitted from the telephone terminal 3 or the like connected to the main apparatus 1 through the LAN 2 to the terminal apparatus connected to the telephone network 7 is transmitted to the control unit 120 through the connection terminal 108 and the LAN I / F 107. Accepted. The packet is supplied from the control unit 120 to the packet disassembly / generation unit 103, where the packet is disassembled, and then transmitted to the telephone network through the telephone network I / F 104 and the connection terminal 105, and transmitted to the intended destination. The

  Further, data from the terminal device connected to the telephone network 7 to the subordinate telephone terminal 3 connected to the main device 1 through the LAN 2 is transmitted to the control unit through the connection terminal 105 and the telephone network I / F 104. 120. The data is supplied from the control unit 120 to the packet decomposing / generating unit 103, where it is converted into a packet of a predetermined format, and then sent to the LAN 2 through the LAN I / F 107 and the connection terminal 108 to be the target telephone terminal 3 Sent to.

  Packets are transmitted and received between the terminal connected to the IP network 6 and the telephone terminal 3 connected to the main apparatus 1 through the LAN 2. For this reason, the packet decomposition / generation unit 103 does not perform packet decomposition or generation, and the IP network I / F 102 and the LAN I / F 107 prepare the data format and transmit / receive it as it is. Similarly, since packets are transmitted and received between the telephone terminals 3 connected to the main apparatus 1 via the LAN 2, the packet disassembly / generation unit 103 does not perform packet decomposition or generation, and does not perform packet decomposition / generation via the LAN I / F 107. Packets are sent and received.

  The terminal management DB 106 is connected to the IP network 6 or the LAN 2 in order to realize the registrar server function, and stores and holds address information about terminal devices that may be called through the main device 1. Specifically, the control unit 120 of the main device 1 receives registration requests (register requests) from various terminal devices connected thereto through the IP network I / F 102 and the LAN I / F 107. In this case, the control unit 120 extracts address information included in the received request. Then, the control unit 120 registers the extracted address information or the like in the terminal management DB 106, or updates the registration information in the terminal management DB 106 using the extracted address information or the like.

  In this way, information registered and managed in the terminal management DB 106 is referred to, and the communication destination requested from the telephone terminal 3 or the like connected to the own device through the LAN 2 is surely specified. Then, the main device 1 realizes a function as a proxy server that transfers information (packet data) to be transmitted to the specified partner. The information registered and managed in the terminal management DB 106 is also used for determining incoming calls to the telephone terminal 3 connected to the own device through the LAN 2.

  FIG. 5 is a diagram for explaining an example of data stored in the terminal management DB 106. The terminal management DB 106 of the main apparatus 1 manages address information about telephone terminals connected to the main apparatus 1 through a LAN, in addition to address information of other IP telephone system terminals connected to the IP network 6. .

  In the terminal management DB 106 of the main apparatus 1 according to this embodiment, as shown in FIG. 5, the extension number, IP address, port number, and various other information ( Register and manage extension registration data (extension information). Here, the extension number and the IP address are assigned in advance to the telephone terminal under the main apparatus 1. The port number is information for specifying a port used for transmission / reception of information between the main apparatus 1 and the telephone terminal, and the information is also predetermined. As other information, for example, URI (Uniform Resource Identifier), MAC (Media Access Control) address, etc. can be registered and managed.

  In addition, management information about a terminal device connected to the IP network 6 managed in the terminal management DB 106 of the main device 1 of this embodiment includes a URI (SIP URI) transmitted from the terminal device and an IP address. It is. Therefore, in the case of a terminal device connected to the IP network 6, the URI is managed instead of the extension number. In addition, it is also possible to manage other transmitted information such as a MAC address. Note that the example shown in FIG. 5 shows an example of stored data for a telephone terminal connected to the main apparatus 1 via a LAN.

  Then, it is assumed that the main apparatus 1 receives a call request (call request) from the telephone terminal 3 of the telephone system of this embodiment to a terminal apparatus connected to the IP network 6. In this case, the control unit 120 of the main device 1 specifies a target destination terminal device based on the management information of its own terminal management DB 106, and transfers a message to the specified terminal device. . Further, it is assumed that the main apparatus 1 accepts an incoming call request (outside line incoming call) to the telephone terminal 3 connected to the LAN 2 through the IP network 6 or the telephone network 7. In this case, the control unit 120 of the main apparatus 1 receives the transmitted message and sends it out to its own system.

  Even if the incoming call is an external line, for example, when the incoming call is an individual incoming call (ie, an incoming call specifying a destination telephone terminal) or an extension call is made between telephone terminals connected to the main apparatus 1 via LAN, the main apparatus 1 Specify the other party and notify the incoming call. In this case, the control unit 120 of the main device 1 specifies the target destination telephone terminal 3 based on the management information of its own terminal management DB 106, and forwards a message to the specified telephone terminal 3. I do.

  Further, when an IP telephone number is used for outgoing calls, although not shown in FIG. 1, a gateway or DNS (Domain Name System) connected to the IP network 6 is used to start from an IP telephone number. A URI or the like is retrieved and used. Similarly, when a call is made from the other party to the telephone terminal 3 constituting the telephone system of this embodiment using the IP telephone number, a gateway or DNS connected to the IP network 6 is used. Thus, the URI is retrieved from the IP telephone number and used.

  As described above, the main apparatus 1 of this embodiment includes the packet decomposition / generation unit 103 and the terminal management DB 106, and relays messages between terminals connected to various networks to which the main apparatus 1 is connected. It is something that can be done. Therefore, the main device 1 according to this embodiment can make a connection between an external line and an internal line, a connection between internal lines, or notify the telephone terminal 3 under the use of a communication line.

  In addition, the control unit 120 can grasp a communication line in use or an empty communication line through the IP network I / F 102, the telephone network I / F 104, and the LAN I / F 107 so that the circuit can be appropriately exchanged. ing. Further, the control unit 120 forms control information for controlling lighting and extinguishing of LEDs and the like to be supplied to each telephone terminal 3 connected through the LAN 2 in accordance with the grasped usage state of the communication line. The control information is transmitted to the LAN 2 through the LAN I / F 107 and the connection terminal 108 and transmitted to each telephone terminal 3 and the like.

[Components that realize call voice recording]
The call voice file 109, the FK input file 110, and the FK setting data file 111 are created on a large-capacity recording medium such as a hard disk, and are used to realize the recording function of the button telephone system of this embodiment. It is a storage unit for various data to be generated. In the following description, it is assumed that the call voice file 109, the FK input file 110, and the FK setting data file 111 are created on a predetermined hard disk. The voice recording unit 112, the FK data management unit 113, and the recording data reproduction unit 114 are processing units used for realizing the recording function in the key telephone system of this embodiment.

[Example of data stored in call voice file 109]
The call voice file 109 stores and holds a series of call voice data for each call. Here, the term “call unit” means that, as described above, one unit is a period from when the communication line is connected until it is disconnected. The series of call voice data is voice data obtained by converting call voice into digital data as described above.

  FIG. 6 is a diagram for explaining an example of data stored in the call voice file 109. As shown in FIG. 6, in the call voice file 109, a series of call voice data is recorded for each call. The call voice file 109 includes, as header information, a call voice file ID, a call start date and time, a call end date and time, a caller telephone number, a caller extension number, a callee telephone number, a callee extension number, and a conference terminal number. 1. Conference terminal number 2, call voice data recording start address, call voice data recording end address are added.

  The call voice file ID is identification information that can uniquely identify the call voice file. The date and time at the start of the call is date and time information indicating the start time of the call acquired from the time information providing unit 115 that provides the current date, current day, and current time at the start of the call. The call end date / time is date / time information indicating the call end time acquired from the time information providing unit 115 at the end of the call. Therefore, the time interval from the time indicated by the call start date and time to the time indicated by the call end date and time can be grasped as the call time.

  The transmission source telephone number is the telephone number of the transmission source that is notified from the transmission source when the main apparatus 1 receives an incoming call. Similarly, the transmission source extension number is the extension number of the transmission source that has been notified by the transmission source when the main apparatus 1 receives an incoming call. This source extension number is mainly used during an extension call. The destination telephone number is a telephone number assigned to a telephone line that has received an incoming call out of one or more telephone lines accommodated by the main apparatus 1. The called extension number is an extension number assigned to the telephone terminal 3 that responds to the incoming call received through the main device 1.

  The conference terminal number 1 and the conference terminal number 2 are extension numbers of the telephone terminals under the main apparatus 1 that are configured to participate in the call later by using the conference call function. In this embodiment, since two telephone terminals 3 can participate in a call later, two storage areas for conference terminal number 1 and conference terminal number 2 are provided.

  The recording start address of the call voice data is information indicating a recording start position on the recording medium of the call voice data in the call voice file. The recording end address of the call voice data is information indicating a recording end position on the recording medium of the call voice data in the call voice file. Along with such header information, call voice data recorded during a call is recorded in the call voice file.

  Then, the call voice file 109 is created for each call unit in which the call voice is recorded. For this reason, in FIG. 6, as indicated by the call voice file ID (1) and the call voice file ID (2), a different file ID is added to the call voice file 109 created for each call and a predetermined hard disk is added. It is accumulated so that it can be distinguished.

[Example of data stored in FK input file 110]
The FK input file 110 stores and holds information about search marks (FK input data). The FK input data is obtained when information indicating that the flexible keys FK1, FK2, and FK3 are operated is provided to the main apparatus 1 from the telephone terminal 3 that is used for a call whose call voice is to be recorded. Formed. FIG. 7 is a diagram for explaining an example of data stored in the FK input file 110. As shown in FIG. 7, to the FK input file 110, the FK input file ID, the extension number, and the call voice file ID of the corresponding call voice file are added as header information.

  The FK input file ID is identification information that can uniquely identify the FK input file. The extension number is an extension number assigned to the telephone terminal 3 that has transmitted information indicating that the flexible key has been operated to the main apparatus 1. The call voice file ID of the corresponding call voice file is identification information (call voice) that uniquely identifies a call voice file that is a recording destination of call voice data generated in a call made using the telephone terminal 3. File ID). As described above, the FK input file 110 is formed for each call voice file, that is, for each series of call voices to be recorded and for each telephone terminal 3 used for the call.

  In the FK input file 110, every time a predetermined flexible key of the telephone terminal 3 used for a call whose call voice is to be recorded is operated, as shown in FIG. , “Record address”, “operation time”, “operation key”, and “other” are recorded. “No.” is a number corresponding to the operation point (operation position) of the flexible key for the call voice data to be recorded. For this reason, “No.” is a small value if it is close to the beginning of the call voice data to be recorded, and a large value if it is far. The “recording address” is information indicating a recording position on the recording medium in which the call voice file 109 that is a recording destination of the call voice data corresponding to the operation point of the flexible key is created.

  The “operation time” is information indicating the time from the beginning of the call voice data corresponding to the operation point of the flexible key. In this embodiment, the operation time is grasped as an elapsed time from the start of recording of the call voice, which is measured by the time information providing unit 115 described later. Note that the current date and time provided by the time information providing unit 115 may be used as the “operation time”. In this case, it is also possible to obtain the time interval of each operation time by holding the date and time information at the start of recording of the call voice, and to use this time interval, or to use an appropriate time after the end of recording. At the timing, the operation time can be converted into an elapsed time from the recording start time of the call voice, and this can be used.

  The “operation key” is information indicating what the operated flexible key is. As the “other” information, for example, information indicating whether the data is formed at the time of recording (recording) of the call voice data or the data formed at the time of reproduction can be added and managed. If the elapsed time from the start of recording is used as the “operation time”, information indicating the actual operation date and time of the flexible key can be managed as “other” information. Various other information can be added and managed.

  In the case of the example shown in FIG. 7, the FK input file ID1 stores information corresponding to the operation of the flexible key from the telephone terminal 3 whose extension number is “101”. The storage location of the corresponding call voice data in this case can be specified by the call voice file ID of the corresponding call voice file. The FK input file ID1 is flexible when the recording address of the call voice data is “XXXX ...” and the operation time corresponding to the playback time from the beginning of the call voice data is “0: 0: 15”. It is recorded that the key FK1 has been operated. Further, the flexible key FK1 is operated when the recording address of the call voice data is “YYYY...” And the operation time corresponding to the playback time from the head of the call voice data is “0: 0: 32”. It has been recorded.

  In the case of the example shown in FIG. 7, the FK input file ID 2 stores information corresponding to the operation of the flexible key from the telephone terminal 3 whose extension number is “102”. The storage location of the corresponding call audio data in this case can be specified by the call audio file ID of the corresponding call audio file. In the FK input file ID2, the recording address of the call voice data is “AAAA...” And the operation time corresponding to the playback time from the beginning of the call voice data is “0: 0: 0”. It is recorded that the key FK2 has been operated. Further, when the recording address of the call voice data is “BBBB...” And the operation time corresponding to the playback time from the head of the call voice data is “0: 0: 45”, the flexible key FK1 is operated. It has been recorded.

  In this way, the FK input file 110 is added for each call voice file created for each call, and for each telephone terminal 3 used for the call, by operating the flexible key. Information related to the search mark (FK input data) is recorded and managed. The FK input data managed in the FK input file 110 becomes a search mark for the telephone terminal 3 for the associated call voice (recorded call voice data).

[Example of data stored in FK setting data file 111]
The FK setting data file 111 stores and holds information indicating a function set (assigned) to a flexible key that can be used in connection with a call voice recording function. FIG. 8 is a diagram for explaining an example of data stored in the FK setting data file 111. In this embodiment, a function for assigning a search mark indicating that it is a call part of the other party is assigned to the flexible key FK1. Further, a function for attaching a search mark indicating that it is a call portion of the user (user of the telephone terminal 3 accommodated in the main device 1) is assigned to the flexible key FK2.

  In addition, a function for attaching a search mark indicating that it is another call part is assigned to the flexible key FK3. Here, for example, when the conference call function is used, the other call part indicates a call part of a destination of a target call and a caller other than himself / herself. Specifically, for example, when the user B of the telephone terminal 3 (1) responds to an incoming call from the outside line by the customer A and starts a call and starts recording the call, the user B alone can handle it. Since it is not possible, it is assumed that the user C of the other telephone terminal 3 (2) participates in the call using the conference call function.

  In this case, when viewed from the user B of the telephone terminal 3 (1), the customer A is the other party, the user B is himself, and the user C of the telephone terminal 3 (2) is the other (other party). It will be. Further, when viewed from the user C of the telephone terminal 3 (2), the customer A is the other party, the user C is himself, and the user B of the telephone terminal 3 (1) is the other (other party). become. This is only an example, and other parties and other parties change depending on the participants of the call.

  Thus, the FK setting data file 111 manages what kind of search mark is added when which flexible key is operated. The information managed in the FK setting data file 111 is, for example, when notifying the user of what kind of search mark is added when the recorded call voice is played back. Will be used.

  In the example of the FK setting data file 111 shown in FIG. 8, the flexible key is used with the same meaning in all the telephone terminals 3 (1), 3 (2),. Is shown. However, it is not limited to this. For example, the function set in the flexible key can be made different for each of the telephone terminals 3 (1), 3 (2),. In this case, in the FK setting data file 111, the flexible key to be used and the function to be set may be managed in association with each of the telephone terminals 3 (1), 3 (2),. .

[Description of each processing unit that realizes call voice recording function]
Next, each processing unit that realizes a call voice recording function and enables use of the recorded call voice in the main apparatus 1 will be described.

  The voice recording unit 112 performs recording processing of the call voice data in the call voice file 109. When the telephone terminal 3 under the main apparatus 1 connects a communication line with an external telephone terminal connected to the IP network 6 or the telephone network 7, the telephone terminal 3 gives an instruction to start recording of call voice. The voice recording unit 112 first creates a call voice file 109 on a predetermined hard disk. Then, the voice recording unit 112 starts a process of recording call voice data corresponding to the call voice for the created call voice file 109. When a telephone terminal 3 under the main apparatus 1 connects a communication line with another telephone terminal under the main apparatus 1, and a telephone voice recording start instruction is issued from one of these telephone terminals In addition, the voice recording unit 112 can similarly start recording the call voice.

  As described above, in the telephone system according to this embodiment, the telephone terminal 3 under the main apparatus 1 can start recording the call voice during a call. Then, as described with reference to FIG. 6, the voice recording unit 112 records the call voice (call voice data) in the call voice file 109 formed on a predetermined hard disk. The call voice file 109 is formed for each call. In this case, the call voice is a two-way call voice of the call voice taken in via the IP network I / F 102 or the telephone network IF 104 and the call voice taken in via the LAN I / F 107 according to the connected communication line. Including.

  Note that, as described above, the voice recording unit 112 functions under the control of the control unit 120, generates the call voice file 109 for each call, and automatically generates the call voice file ID, so that the call voice file It is added to the header part 109. Also, the voice recording unit 112 receives the call start date and time and the call end date and time provided by the control unit 120 from the time information providing unit 115 and adds them to the header portion of the corresponding call voice file 109. In addition, various telephone number information such as a caller telephone number and a caller extension number are provided by the control unit 120 extracted from information from a caller or a callee, and a header part of a corresponding call voice file 109 is received. Append to

  Also, the recording start address and the recording end address of the call voice are acquired from the predetermined hard disk in which the call voice file 109 is formed by the voice recording unit 112 when the call voice data is recorded in the call voice file 109. It is added to the header part. Further, the voice recording unit 112, in the case of packetized call voice data captured through the IP network I / F 102 or the LAN I / F 107, performs processing such as packet decomposition and conversion into call voice data of a predetermined format. Also do.

  The FK data management unit 113 performs processing such as generation of the FK input file 110, recording of information related to the search mark in the FK input file 110, and deletion of information related to the search mark recorded in the FK input file 110. Do. Specifically, it is assumed that the FK data management unit 113 first receives the operation information of the flexible key from the telephone terminal 3 subordinate to the main apparatus 1 used for a call that is a recording target of the call voice.

  In this case, the FK data management unit 113 generates the FK input file 110 on a predetermined hard disk according to the operation information, prepares the FK input data, and records this in the FK input file. Thereafter, every time the flexible key operation information is received from the telephone terminal 3, the FK data management unit 113 prepares FK input data and records it in the FK input file.

  Further, the FK data management unit 113 performs FK input data to the corresponding FK input file 110 in accordance with flexible key operation information from the telephone terminal 3 that has instructed reproduction of the recorded call voice to be reproduced. Add and delete processes. Thereby, at the time of recording the call voice, a search mark can be added to the recorded call voice. Further, when the recorded call voice is reproduced, a new search mark can be added or an unnecessary search mark can be deleted.

  The recorded data playback unit 114 performs playback processing of the recorded call voice in response to an instruction from the telephone terminal 3 subordinate to the main device 1. The time information providing unit 115 provides the current date, current day, and current time. In addition, as described above, the time information providing unit 115 corresponds to the elapsed time from the recording start time of the call voice (the playback time from the beginning of the call voice data) when the call voice recording function is used. It also has a function to measure (count) and provide this.

[Processes related to call recording function in the phone system]
Next, in the telephone system of this embodiment configured by the main apparatus 1 and the telephone terminal 3 having the above-described configuration, the call voice is recorded by the call recording function, the search mark is added, and the recording is performed. The processing when using the call voice that has been used will be specifically described. In the following, it is divided into (1) processing related to call recording at the time of on-call, (2) processing related to call recording when hold / transfer occurs, and (3) processing related to call recording when using the conference call function. This will be specifically described.

  On-call means, for example, an incoming call to a specific telephone number for which usage is determined, such as an incoming call to a specific telephone number that accepts an inquiry from a customer. Also, since the recorded call voice playback process is basically performed in the same manner regardless of how it is recorded, (1) the case where it is performed after the process related to call recording during on-call is taken as an example. Will be explained.

[(1) Processing related to call recording during on-call]
FIG. 9 is a sequence diagram for explaining an example of processing during an on-call. Out of a plurality of telephone numbers accommodated in the main apparatus 1, for example, an incoming call is generated for a predetermined telephone number provided to receive an inquiry from a customer exclusively (step S <b> 1). Assume that an incoming call is notified to a plurality of subordinate telephone terminals 3 (1), 3 (2),... (Step S2). Then, it is assumed that the user of one of the telephone terminals 3 (1), 3 (2),... Notified of the incoming call performs an off-hook operation (step S3) and responds to the incoming call. In this case, the control unit 320 of the telephone terminal 3 forms an incoming call response and transmits it to the main device 1 (step S4).

  The main apparatus 1 that has received the incoming call response from the telephone terminal 3 connects the communication line between the caller and the telephone terminal 3 that has responded to the incoming call, and prepares a state in which a call can be made (step S5). As a result, a call can be made between the caller user and the user of the telephone terminal 3. The incoming call received from the call made by the user of the telephone terminal 3 with the caller is an inquiry from the customer and includes a slightly complicated content. Suppose you decide to go. In this case, it is assumed that the user of the telephone terminal 3 inputs a recording start instruction to the telephone terminal 3 by pressing the recording button provided in the operation input unit 311 of the telephone terminal 3 (step S6). ).

  The control unit 320 of the telephone terminal 3 that has received the recording start instruction forms a call voice recording start request and transmits it to the main device 1 (step S7). In the main apparatus 1 that has received the call voice recording start request, the control unit 120 forms a recording start response and returns this to the requesting telephone terminal 3 (step S8). Then, the control unit 120 controls the voice recording unit 112 to make a call transmitted / received between the caller telephone terminal to which the communication line is connected via the main apparatus 1 and the callee telephone terminal 3. A process of recording voice (call voice data) in a call voice file 109 formed on a predetermined hard disk is started (step S9).

  As described above, when the telephone terminal 3 subordinate to the main apparatus 1 responds to an incoming call to a predetermined telephone number, the main apparatus 1 automatically starts recording the call voice. Is also possible. However, in this embodiment, in order to simplify the explanation, a case where recording of a call voice is started when a recording start instruction is received from a user of the telephone terminal 3 will be described as an example.

  In the process of step S9, after the recording of the call voice is started, a search mark can be added to the call voice to be recorded through the telephone terminal 3 used for the call. As shown in FIG. 9, the user of the telephone terminal 3 who is making a call operates one of the flexible keys FK1, FK2, and FK3 as necessary (step S10). In this case, the control unit 320 of the telephone terminal 3 forms flexible key information (hereinafter abbreviated as FK information) including an extension number, information for specifying the operated flexible key, and the like, and transmits it to the main apparatus 1. (Step S11).

  In the main apparatus 1 that has received the FK information, the FK data management unit 113 functions under the control of the control unit 120 and executes a process of adding a search mark (step S12). In step S12, as described above, the FK data management unit 113 functions under the control of the control unit 120, generates FK input data in accordance with the operated flexible key, and generates the corresponding FK input. Processing to record in the file 110 is performed. If the corresponding FK input file 110 does not exist on a predetermined hard disk, the FK data management unit 113 also performs processing for forming the file.

  In FIG. 9, the processes from step S10 to step S12 surrounded by a dotted line can be repeatedly performed. Therefore, during a call, search marks can be added to a plurality of locations determined by the user to be necessary for the call voice to be recorded through the telephone terminal 3 used for the call. Also, as described above, different functions are assigned to each of the plurality of flexible keys operated to add the search mark.

  That is, the flexible key FK1 has a function for adding a search mark to the other party's call part, the flexible key FK2 to the own call part, and the flexible key FK3 to the other call part. Is assigned. Therefore, by using the flexible keys FK1, FK2, and FK3 properly, different search marks can be added depending on the speaker. As a result, it is possible to reproduce and listen only to the other party's call portion or to reproduce and listen only to the call portion of the user (self) of the telephone terminal 3.

  Then, when the call ends, for example, when an on-hook operation is performed on the telephone terminal used by the other party, a call end request is transmitted from the other party to the main apparatus 1 (step S13). ). The main apparatus 1 transmits the call termination request to the subordinate telephone terminal 3 that has been in a call with the partner (step S14). After that, the main device 1 releases the communication line connected between the telephone terminal of the other party and the telephone terminal 3 under its control (step S15), and ends the call recording (step S16). ). Of course, the telephone terminal 3 under the control of the main apparatus 1 may perform an on-hook operation before the other party. In this case, the main apparatus 1 transmits a call end request to the other party and releases the communication line. It will be.

  In addition, the main device 1 of this embodiment performs a process of adding the search mark (FK input data) stored in the FK input file 110 to the corresponding call voice file 109 (step S17). By doing so, the search mark (FK input data) and the call voice data can be managed by one file, and backup can be appropriately performed and easy to use later.

  In the following description, it is assumed that the call voice file 109 and the FK input file 110 formed corresponding thereto exist in the main apparatus 1. That is, the process performed in step S17 is not an essential process, and it is only necessary to ensure that the call voice file 109 and the FK input file 110 formed in correspondence therewith can be maintained.

  Next, by repeating the processing of step S10 to step S12 shown in FIG. 9, a search mark is set for the call voice to be recorded through the telephone terminal 3 under the main apparatus 1 that responds to the incoming call. A specific example of processing when adding will be described. FIG. 10 is a diagram for explaining a specific example of processing when a search mark is added to a call voice to be recorded. In FIG. 10, as indicated by the arrows, the horizontal direction in the figure is the time axis, and the upper left corner is the incoming call response position for the on-call (when the incoming call response is made). Further, in FIG. 10, in this example, a position (time point) at which the communication line is released by the caller performing on-hook in this example is present, and then the recording of the call voice is terminated. (Time) exists.

  Then, as shown in the upper left corner of FIG. 10, the user of the telephone terminal 3 subordinate to the main apparatus 1 performs an operation to respond to an incoming call, whereby the caller telephone terminal and the main apparatus 1 A communication line is connected to the telephone terminal 3 under the control of the telephone line 3 to enable a telephone call. The user of the telephone terminal 3 listens to the requirements of the caller (partner) by making a call through the connected communication line. Here, it is assumed that the requirement of the other party is, for example, an inquiry about a product handled by the company, and the user of the telephone terminal 3 determines that it is necessary to record the call voice.

  In this case, as shown in FIG. 10, the user of the telephone terminal 3 performs the recording start operation at the operation time point t1, and uses the flexible key FK1 to add a search mark to the voice of the other party to be recorded. Is pressed. The recording start operation is an operation of pressing the recording button of the operation input unit 311 of the telephone terminal 3. As a result, as described with reference to FIG. 9, the recording start request is transmitted from the telephone terminal 3 to the main apparatus 1. In this case, the voice recording unit 112 functions in the main device 1 to create a call voice file 109 (FIG. 6) and start a process of recording the call voice in the call voice file 109.

  Further, as described with reference to FIG. 9, the FK information is transmitted to the main apparatus 1 by the pressing operation of the flexible key FK1. In this case, the FK data management unit 113 functions in the main device 1, creates the FK input file 110 (FIG. 7), forms FK input data according to the operation of the flexible key by the user of the telephone terminal 3, The process of recording in the FK input file 110 is started. As described with reference to FIG. 7, the FK input file 110 is formed for each phone call file 3 and for each telephone terminal 3 on which a flexible key under the main apparatus 1 is operated.

  In this way, recording of the call voice is started, and for each call voice file and for each telephone terminal 3 under the main apparatus 1, the search is performed in response to the pressing operation of the flexible key by the user of the telephone terminal 3. Marks can be added. At the operation time t1, FK input data (search mark) indicating that the flexible key FK1 has been operated by the user of the telephone terminal 3 is formed in the FK data management unit 113 of the main device 1, and this is FK. Recorded in the input file 110.

  Usually, after listening to an inquiry from the other party, the user of the telephone terminal 3 answers the other party or asks the other party a question in order to make an appropriate answer. The user of the telephone terminal 3 adds a search mark different from the search mark added to the other party's call voice part to his / her call voice part.

  For this reason, as shown at the operation time t2 in FIG. 10, the user of the telephone terminal 3 presses the flexible key FK2 in the portion that he / she mainly speaks (the voice portion of his / her call). Thereby, at the operation time t2, FK input data (search mark) indicating that the flexible key FK2 has been operated by the user of the telephone terminal 3 is formed in the FK data management unit 113 of the main device 1, Recorded in the FK input file 110.

  Even after this, the user of the telephone terminal 3 presses the flexible key FK1 when the other party speaks mainly and presses the flexible key FK2 when he / she mainly speaks. In the example shown in FIG. 10, the user of the telephone terminal 3 depresses the flexible key FK1 at the operation time t3, depresses the flexible key FK2 at the operation time t4, and at the operation time t5. It shows that the flexible key FK1 has been pressed.

  Therefore, in the case of the example shown in FIG. 10, at the operation time t3, FK input data (search mark) indicating that the flexible key FK1 has been operated by the user of the telephone terminal 3 is the main device 1. And is recorded in the FK input file 110. Further, at the operation time t4, FK input data (search mark) indicating that the flexible key FK2 has been operated by the user of the telephone terminal 3 is formed in the FK data management unit 113 of the main device 1, and this is FK. Recorded in the input file 110. Further, at the operation time t5, FK input data (search mark) indicating that the flexible key FK1 has been operated by the user of the telephone terminal 3 is formed in the FK data management unit 113 of the main device 1, and this is FK. Recorded in the input file 110.

  Thereafter, the call is terminated, for example, by performing an on-hook operation at the caller's telephone terminal, a call termination request is provided to the main apparatus 1, and the communication line is released as shown in the lower right portion of FIG. The call voice recording process ends. When the recording of the call voice is completed, the call voice file 109 and the FK input file 110 are also closed. Accordingly, the call voice from the operation time point t1 when the recording start operation shown in the upper left part of FIG. 10 is performed to the recording end time point shown in the lower right part of FIG. 10 is stored in one call voice file 109. The Further, the five FK input data formed at the operation time points t1, t2, t3, t4, and t5 are stored and managed in one FK input file 110.

  As described with reference to FIGS. 6 and 7, the call voice file 109 and the FK input file 110 are linked by the file ID of the call voice file 109. For this reason, the FK input data stored in the FK input file 110 is a search mark for the call voice data stored in the associated call voice file.

[Replay processing of recorded call voice]
Next, the process of reproducing the call voice recorded in the call voice file 109 of the main apparatus 1 through the process described with reference to FIGS. 9 and 10 will be described. FIG. 11 is a sequence diagram for explaining an example of a recorded call voice reproduction process.

  When the user of the telephone terminal 3 subordinate to the main device 1 listens to the recorded call voice during a call using the telephone terminal 3, the user presses the playback button provided on the operation input unit 311 of the telephone terminal 3. A pressing operation is performed (step S21). In this case, the control unit 320 of the telephone terminal 3 forms a reproduction request for the recorded call voice and transmits it to the main apparatus 1 (step S22). The reproduction request includes the extension number of the telephone terminal 3.

  In the main apparatus 1 that has received the reproduction request, the recorded data reproduction unit 114 functions under the control of the control unit 120, and the extension number included in the reproduction request is changed to a destination extension number, a destination extension number, a conference terminal. The call voice file 109 included in either the number 1 or the conference terminal number 2 is specified. Then, the recorded data reproduction unit 114 reads out the call voice data stored in the identified call voice file 109 and starts a process of transmitting it to the telephone terminal 3 that is the reproduction request source (step S23). Thereby, the call voice data stored in the specified call voice file 109 is transmitted to the telephone terminal 3 that is the reproduction request source (step S24).

  It is assumed that there are a large number of call voice files 109 that include the extension number of the telephone terminal 3 that is the reproduction request source in any of the destination extension number, the destination extension number, the conference terminal number 1, and the conference terminal number 2. In this case, the recorded data reproduction unit 114 creates a list of the extracted call voice files 109 and provides the list to the telephone terminal 3 that is the reproduction request source. The list of the call voice file 109 includes a call voice file ID, a call start date and time, information indicating a caller, and information indicating a callee.

  Further, in the case of a call voice file 109 when a conference call function described later is used, information corresponding to the conference terminal number 1 and information corresponding to the conference terminal number 2 are also included. Here, the information indicating the originator, the information indicating the destination, the information corresponding to the conference terminal number 1, and the information corresponding to the conference terminal number 2 are respectively a telephone number and an extension number, or a telephone number and an extension number. Names and names registered in correspondence.

  That is, it is stored in a telephone directory created on a recording medium such as a RAM of the main apparatus 1 in the telephone number of the caller and the callee, the extension number of the caller and the callee, and the conference terminal numbers 1 and 2. It is assumed that the extension number is registered. In this case, information such as name and name registered corresponding to these is information indicating the sender, information indicating the destination, information corresponding to the conference terminal number 1, and information corresponding to the conference terminal number 2. Information. It is assumed that no telephone number or extension number corresponding to the telephone directory is registered. In this case, the corresponding telephone number or extension number is used as it is as information indicating the call originator, information indicating the destination, information corresponding to the conference terminal number 1, and information corresponding to the conference terminal number 2.

  The telephone terminal 3 that is the reproduction request source that has received the list of the call voice file displays the information on the list on the display 314, and a predetermined operation key of the operation input unit 311 is operated. Can be scrolled. Then, the user of the telephone terminal 3 operates the playback button of the operation input unit 311 when the information about the target call voice file is displayed on the display 314. Thereby, the control unit 320 of the telephone terminal 3 forms a reproduction request including the extension number assigned to the own terminal and the call voice file ID of the call voice file, and transmits the reproduction request to the main apparatus 1.

  Under the control of the control unit 120, the recorded data playback unit 114 of the main device 1 sequentially reads the call voice data from the call voice file specified by the call voice file ID included in the playback request, To the telephone terminal 3 (step S23, step S24).

  The telephone terminal 3 receives the call voice data from the main device 1 through the LAN connection terminal 301 and the LAN I / F 302. Then, the received call voice data is packet-decomposed by the packet processing unit 303, converted into an analog voice signal by the call voice input / output I / F 304 and supplied to the handset 306, and the reproduced voice is emitted from the handset 306 (step S25). ). Thereby, the user of the telephone terminal 3 can reproduce and listen to the intended call voice recorded during the call using the telephone terminal 3.

  In this manner, after the recorded call voice is started to be reproduced, the target reproduction position search process using the search mark added at the time of recording can be performed. In the telephone terminal 3 of this embodiment, when reproducing the call voice, a jump key in the direction in which the time advances (forward jump key), a jump key in the direction in which the time returns (rear jump key), and a fast forward key Each function with the fast reverse key is assigned a different numeric key.

  The forward jump key is for jumping (advancing) the reproduction position to the position indicated by the search mark added first in the direction in which the time advances from the current reproduction position. The backward jump key is for jumping (returning) the playback position to the position indicated by the search mark that is first added in the direction of returning time from the current playback position.

  In the telephone terminal 3 of this embodiment, the function keys used for the search described above are assigned to the four numeric keys sandwiching the numeric key “5”. Specifically, the function of the forward jump key is assigned to the numeric key “2”, and the function of the backward jump key is assigned to the numeric key “8”. Further, the function of the fast reverse key is assigned to the numeric key “4”, and the function of the fast forward key is assigned to the numeric key “6”.

  When searching for the desired playback position in the recorded call voice during playback processing of the recorded call voice, the forward jump key, backward jump key, fast forward key, and fast reverse key are operated. A search instruction is input (step S26). In this case, the control unit 320 of the telephone terminal 3 forms a search request including the extension number of the telephone terminal 3 and information for specifying the operated numeric key, and the search request is mainly transmitted through the LAN I / F 302 and the LAN connection terminal 301. It transmits to the apparatus 1 (step S27).

  When the control unit 120 of the main apparatus 1 receives a search request from the telephone terminal 3 through the LAN connection terminal 108 and the LAN I / F 107, the control unit 120 performs specific processing based on the information specifying the operation key included in the search request. Specific requirements are identified. That is, it is specified whether the request is a forward jump request, a backward jump request, a fast forward request, or a fast reverse request. Then, the control unit 120 controls the recording data reproduction unit 114 so as to perform processing according to the specified request, and executes processing according to the search request from the telephone terminal 3 (step S28).

  Here, a specific example of the search process performed by the control unit 120 and the recorded data reproduction unit 114 will be described. For example, the search request from the telephone terminal 3 is a forward jump request formed by pressing the forward jump key (the numeric key “2”). In this case, the control unit 120 refers to the FK input file having the extension number included in the search request from the telephone terminal 3 and the file ID of the call voice file being played in the header part.

  Then, the control unit 120 is first added among the search marks attached in the direction in which the time advances with reference to the reproduction address corresponding to the current reproduction position provided from the recorded data reproduction unit 114. Identify the search mark that you have. Then, the control unit 120 acquires the recording address of the specified search mark (FK input data), and provides the recorded data reproduction unit 114 with an instruction to jump the reproduction position to the position indicated by the recording address.

  Based on the control of the control unit 120, the recorded data reproduction unit 114 positions the reproduction position at the recording position of the call voice file 109 indicated by the recording address of the FK input data as a search mark, and records the recorded call voice. Perform playback. That is, the recorded data reproduction unit 114 moves the reproduction position of the call voice file 109 being reproduced to the position indicated by the recording address, reads the call voice data from the newly instructed position, The process of transmitting to the telephone terminal 3 is performed.

  Such a series of processes is performed in step S28 of FIG. Here, the case where the forward jump is performed has been described, but the same can be performed when the backward jump is performed. The only difference between forward jump and backward jump is whether to search for the search mark in the direction of time advance or search for the search mark in the direction of time return based on the current playback position. is there.

  In addition, when the fast-forward key is operated, a process of moving the reproduction position in the direction in which the time advances at high speed is performed until the fast-forward key is operated again. Similarly, when the fast reverse key is operated, a process of moving the playback position in a direction in which the time returns at high speed is performed until the fast reverse key is operated again. Therefore, the playback position is adjusted while operating the fast-forward key and the fast-rewind key, and the playback voice of the call voice from the adjusted position is listened to, and the call voice data of the desired call contents is searched for and used. You can play and listen to the voice of the call.

  In addition, for example, a search mark used for jumping the playback position in response to the pressing operation of the forward jump key (the numeric key “2”) is pressed by pressing the flexible key FK1 and the other party's call. Suppose that it was attached to the audio part. Thereafter, in the telephone terminal 3 of this embodiment, when the forward jump key is pressed twice in a so-called double click manner, the next search mark added by operating the flexible key FK1 is displayed. The playback position can be jumped to the indicated position.

  In this case, the FK data management unit 113 is a search mark added by operating the same operation key as the search mark used immediately before, and the search mark (FK) positioned next in the direction in which the time advances. Input data) is specified from the currently used FK input file. Then, a process of positioning the reproduction position at the position indicated by the recording address of the specified search mark (FK input data) is performed. In this way, the playback position can be jumped so that only the search mark added to the call voice portion of the other party is operated by operating the flexible key FK1.

  Of course, the same processing can be performed when the backward jump key (the numeric key “8”) is pressed. That is, the process when the backward jump key is pressed and the process when the forward jump key is pressed are the same except that the search direction of the playback position is different. In addition, a search mark used to jump the playback position in response to the pressing operation of the forward jump key or the backward jump key is added by pressing the flexible key FK2 or the flexible key FK3, for example. The same processing can be performed when there is something.

  Moreover, the process of step S26-step S28 can be performed repeatedly. That is, by repeatedly operating the forward jump key (number key “2”) and the backward jump key (number key “8”), a jump is sequentially made to the position indicated by the next search mark in the designated direction. be able to. In addition, by repeatedly operating the fast-forward key (number key “6”) and the fast-rewind key (number key “4”), the beginning and end of fast-forward and fast-rewind are repeated, so that the target playback position is set. The search can be easily performed.

  Furthermore, in the telephone system of this embodiment, when a recorded call voice is played back, a search mark can be added and added to the recorded call voice in the same manner as during a call. . In other words, the flexible key FK1 to which a function for attaching a search mark is assigned through the telephone terminal 3 that plays back and listens to the recorded call voice as necessary even when the recorded call voice is played back. , FK2 and FK3 are operated (step S29). In response to this, the control unit 320 of the telephone terminal 3 generates FK information and transmits it to the main apparatus 1 (step S30). In main apparatus 1, when FK information is received from telephone terminal 3, control unit 120 controls FK data management unit 113 to form FK input data and additionally record this in corresponding FK input file 110. Is performed (step S31).

  In step S31, the FK data management unit 113 acquires the playback address of the recorded call voice data at the time when the FK information is provided through the recording data playback unit 114. FK input data is generated using this reproduction address as a recording address in the FK input data, and additionally recorded in the FK input file 110. In this case, when data is added to the FK input file 110, the data is recorded in the order according to the recording address. As described above, the processes in steps S29 to S31 shown in FIG. 11 are processes corresponding to steps S10 to S12 shown in FIG. And the process of step S29-step S31 shown in FIG. 11 can also be repeatedly performed as needed.

  In FIG. 11, after the search mark addition process is performed by the processes of steps S29 to S31, the processes of steps S26 to S28 can be repeated. That is, a series of processing from step S26 to step S28 and a series of processing from step S29 to step S31, which are surrounded by a dotted line in FIG. 11, are performed as necessary during the reproduction processing of the recorded call voice. Can be repeated. Therefore, after adding and adding a search mark by the processing from step S29 to step S31, the processing from step S26 to step S28 can be repeated to search for the reproduction position.

  Thereafter, when the recorded call content is confirmed through the recorded call voice reproduction process, the user of the telephone terminal 3 performs an on-hook operation (step S32). Thereby, the communication line connected between the main device 1 and the telephone terminal 3 is released (step S33). Then, the control unit 120 of the main device 1 controls the recorded data reproduction unit 114 to end the recorded voice call reproduction process (step S34).

[Search mark deletion processing]
In some cases, the search mark added to the recorded call voice may be deleted. When the recorded call voice is reproduced, the user of the telephone terminal 3 depresses the forward jump key or the backward jump key as described above, and the reproduction position is at the position indicated by the recording address of the added search mark. Position the to play the recorded call voice and listen to it. Then, it is assumed that the call voice part that has been listened to has no meaning, and it has been found that it is better to delete the search mark used immediately before the reproduction position is positioned.

  In this case, the user of the telephone terminal 3 who is listening to the recorded call voice performs a predetermined operation on the telephone terminal 3 so that the search mark used immediately before the reproduction position is positioned. Can be deleted. In the telephone system of this embodiment, for example, the flexible key FK8 is used as a deletion key for deleting the added search mark. Therefore, as described above, when it is desired to delete the search mark used immediately before the position of the reproduction position, the flexible key FK8 to which the search mark deletion function is assigned is pressed.

  When the flexible key FK8 is pressed, the telephone terminal 3 forms FK information indicating that the flexible key FK8 has been operated and transmits the FK information to the main apparatus 1. In the main apparatus 1 that has received FK information indicating that the flexible key FK8 has been operated, the control unit 120 controls the FK data management unit 113 and is used to position the playback position most recently from the corresponding FL input file. FK input data (search mark) is deleted. In this way, search marks that are no longer needed can be deleted.

  Prior to the deletion, the main device 1 transmits a confirmation message to the requesting telephone terminal 3 as to whether or not the search mark used immediately before can be deleted. Then, for example, when a confirmation response transmitted by pressing the flexible key FK8 is received again from the telephone terminal 3, the search mark is deleted such that the search mark is deleted. It can also be.

[Displays for search marks during recording and playback of call audio]
Further, in the telephone system of this embodiment, at the time of recording the call voice or reproducing the recorded call voice, the information on the search mark added or used immediately before is displayed on the display of the telephone terminal 3. 314 can be displayed. FIG. 12 is a diagram for explaining a display example of information related to the search mark on the display 314 of the telephone terminal 3.

[Display Example on Display 314 of Telephone Terminal 3 During Recording of Call Voice]
First, display of information on the display 314 of the telephone terminal 3 during recording of a call voice will be described. When a call is recorded using the telephone terminal 3 under the control of the main apparatus 1, if a call voice is recorded, a display as shown in FIG. 12A is displayed on the display 314 of the telephone terminal 3. be able to. In the display example of FIG. 12A, “display indicating that a call is in progress” and “call time” are displayed at the top. In the display example of FIG. 12A, it is shown that the call time has elapsed “0 hour 1 minute 46 seconds” from the start of the call. These displays can be performed by the function of the control unit 320 of the telephone terminal 3. The “call time” is an elapsed time from the start of the call and is not shown in FIG. 2, but is measured and displayed by using a function of a time information providing unit (so-called clock circuit) provided in the telephone terminal 3. it can.

  When a search mark is added by operating the flexible keys FK1, FK2, and FK3 as described above during recording of a call voice, information related to the search mark is displayed. The display example in FIG. 12A shows a case where “No.”, “grant time”, and “give mark” are displayed together with these headings as information relating to the search mark.

  Here, “No.” is information indicating the number of the search mark added to the call voice being recorded from the head position of the call voice. The “granting time” corresponds to the elapsed time from the recording start time of the call voice being recorded, and the time measured by the time information providing unit 115 by the FK data management unit 113 when the FK input data is generated is used. . The “grant mark” is information indicating the operated flexible key notified by the FK information from the telephone terminal 3. These pieces of information are provided from the main apparatus 1 to the telephone terminal 3 and used.

  That is, when the process of adding a search mark is performed in the process of step S12 shown in FIG. 9, the control unit 120 of the main apparatus 1 displays “No.”, “ “Grant time” and “Grant mark” are provided to the telephone terminal 3. Then, the telephone terminal 3 displays information from the main device 1 on the display 314 through the display controller 313. In the case of the example shown in FIG. 12 (A), the position of the call voice to be recorded is the first from the head and the elapsed time from the head of the call voice is “0 hour 0 minute 35 seconds”. In addition, it is shown that the flexible key FK1 (partner) is operated to add a search mark.

  In the case of the display example shown in FIG. 12A, information indicating flexible keys that can be operated is displayed at the lower end of the display 314. That is, the flexible key FK1 adds a search mark to the other party's call part, the flexible key FK2 adds to the own call part, and the flexible key FK3 adds another search mark to the other call part. Indicates that it can be operated.

  As a result, how many search marks are added to the voice of the call being recorded, and the most recently added search mark indicates which flexible key is positioned at the position where the call voice recording has started. It is possible to notify the user of the telephone terminal 3 whether or not it is added by operating.

[Example of display on the display 314 of the telephone terminal 3 during playback of the call voice]
Next, information display on the display 314 of the telephone terminal 3 during the reproduction of the recorded call voice will be described. FIG. 12B is a display example when a search position is searched using a search mark, and FIG. 12C is a display example when a search mark is added. .

  As described above, when the recorded call voice is reproduced, the search mark added to the call voice to be reproduced is operated by operating the forward jump key or the backward jump key. Assume that the playback position is jumped. In this case, a display as shown in FIG. 12B can be displayed on the display 314 of the telephone terminal 3.

  In the display example of FIG. 12B, a display indicating that the recorded call voice is “playing”, a display indicating the playback time from the beginning of the recorded call voice, and a recording are recorded at the top. The display shows the total recording time of the call voice. “Now playing” can be displayed by the function of the control unit 320 of the telephone terminal 3. Further, the playback time and the recording time can be displayed based on information from the main device 1. In the display example of FIG. 12B, it is shown that the playback time is “0 hour 0 minute 40 seconds” and the recording time is “0 hour 6 minutes 23 seconds”.

  When the recorded call voice is being played back and the playback position is jumped using the forward jump key or the backward jump key, information on the search mark (FK input data) used for positioning the playback position by the operation. Is displayed. In the display example of FIG. 12B, as in the case of the call shown in FIG. 12A, “No.”, “grant time”, “grant mark” The case where it displays with these headings is shown.

  In this case, information relating to the search mark used when the playback position is jumped using the forward jump key or the backward jump key is displayed. In the case of the display example shown in FIG. 12B, “No.” is “01”, “grant time” is “0 hour 0 minute 35 seconds”, and “grant mark” is “FK1 ( "Other party)" is displayed. This is most recently given from the beginning of the call voice to be played and the flexible key FK1 is operated at the position where the elapsed time from the head of the call voice is “0 min 35 sec 23”. It is shown that the playback position is positioned by using the searched search mark. Therefore, the user can recognize how far away from the used search mark is the current playback position by looking at the given time and playback time.

  Even during playback of the recorded call voice, the search mark can be added and added by operating the flexible keys FK1, FK2, and FK3 as described above. In this case, information on the added prefecture search mark is displayed. FIG. 12C shows a display example on the display 314 of the telephone terminal 3 when an operation for adding a search mark is performed during reproduction of the recorded call voice.

  Also in the case of the display example of FIG. 12C, a display indicating that the recorded call voice is “playing”, a display indicating the playback time from the beginning of the recorded call voice, The recording time of the recorded call voice is displayed. In the display example of FIG. 12C, it is shown that the playback time is “0 hour 0 minute 57 seconds” and the recording time is “0 hour 6 minutes 23 seconds”.

  Also in the case of the display example of FIG. 12C, as in the case of FIGS. 12A and 12B, the information related to the search mark includes “No.”, “Grant time”, “Grant mark”. It is. As shown in FIG. 12C, the added mark is displayed with an “add” character to indicate that it is a search mark added at the time of reproduction. These pieces of information can also be displayed on the display 314 of the telephone terminal 3 based on the information from the main device 1 as in the case of recording the call voice.

  In the case of the example shown in FIG. 12C, the position of the call voice to be reproduced is the second from the beginning, and the elapsed time from the beginning of the call voice is “0 hour 0 minute 51 seconds”. Further, it is shown that the search key is additionally added by operating the flexible key FK2. Also in this example, the user can recognize how far away from the additionally assigned search mark is the current reproduction position by looking at the addition time and the reproduction time.

  Also, information indicating flexible keys that can be operated is displayed at the lower end of the display 314 even when the recorded call voice shown in FIGS. 12B and 12C is reproduced. It is also shown that the flexible key FK8 can be operated as a search mark deletion key that was not recorded during playback.

  As described above, at the time of recording the call voice or reproducing the recorded call voice, it is possible to display information about the added search mark and information about the search mark used for the latest search of the playback position. Therefore, the user of the telephone terminal 3 can accurately recognize the position where the search mark is added, what kind of search mark is added, or whether it is added in the call voice that is to be recorded or played back. . This makes it possible to appropriately add the search mark addition frequency and to properly grasp the reproduction position.

[(2) Processing related to call recording when hold / transfer occurs]
Next, processing related to call recording when hold / transfer occurs will be described. In the above-described processing related to call recording during an on-call, a call is made only between the caller and the telephone terminal 3 subordinate to the main apparatus 1. However, for example, the user of the telephone terminal 3 may not be able to handle it alone, or it may be better for another specialized person to handle it. In such a case, holding / transfer is generally performed. And in the telephone system of this embodiment, even when hold / transfer is performed, it is possible to appropriately record the call voice.

  FIGS. 13 and 14 are sequence diagrams for explaining processing related to call recording in the case where a hold / transfer occurs. First, as shown by being surrounded by a dotted line in FIG. 13, the same processing as in steps S1 to S12 in FIG. 9 is performed, and the telephone terminal 3 (1 ), A communication line is connected, and recording of the call voice is started. That is, in the main apparatus 1, a call voice file 109 is created and recording of the call voice is started. In addition, the FK input file 110 is formed according to the flexible key operation of the user of the telephone terminal 3 (1), and the process of recording the FK input data formed according to the flexible key operation is started. Has been.

  Thereafter, since the inquiry from the other party is technical and the user of the telephone terminal 3 (1) cannot sufficiently respond, the communication line is put on hold and the telephone terminal 3 (N ). In this case, the user of the telephone terminal 3 (1) obtains the consent to call the specialized department to the other party and presses the hold button of the operation input unit 311 of the telephone terminal 3 (1). Is performed (step S41). In response to the hold operation, the control unit 320 of the telephone terminal 3 (1) forms a hold request and transmits it to the main device 1 (step S42).

  The main device 1 that has received the hold request transmits a hold response to the requesting telephone terminal 3 (1) (step S 43), and puts the communication line into a line holding state that is not connected to the subordinate telephone terminal 3. (Step S44). And the control part 120 of the main apparatus 1 transmits a holding sound to the other party's telephone terminal (step S45).

  On the other hand, the telephone terminal 3 (1) that has performed the hold operation inputs the extension number of the telephone terminal 3 (N) of the specialized department, and makes an extension call (step S46). Thereby, the control part 320 of the telephone terminal 3 (1) forms the extension request | requirement containing the input extension number, and transmits this to the main apparatus 1 (step S47). The main device 1 that has received the extension request forms an extension notification for the telephone terminal 3 (N) specified by the extension number included in the extension request, and transmits this to the telephone terminal 3 (N) (step S48). ).

  In the telephone terminal 3 (N) that has received the extension notification (notification that an incoming call has occurred), the control unit 320 performs incoming notification processing such as using a ringing tone or flashing a predetermined LED. Done. Then, when the user of the telephone terminal 3 (N) that is the destination of the extension performs an off-hook operation (step S49), the control unit 320 of the telephone terminal 3 (N) forms an extension response, which is used as the main device 1 (Step S50).

  The main apparatus 1 that has received the extension response connects a communication line between the telephone terminal 3 (1) that is the extension source and the telephone terminal 3 (N) that is the extension destination. And, since the inquiry content is professional through the connected communication line, I would like to respond, and I want to transfer the call (I want to transfer the communication line connected to the caller) by extension call Tell (step S51). If the user of the telephone terminal 3 (N) agrees to transfer the telephone, the process proceeds to FIG.

  In this case, the user of the transfer source telephone terminal 3 (1) performs an on-hook operation (step S52) and ends the call. Thereby, the control part 320 of the telephone terminal 3 (1) forms a call termination request, and transmits this to the main apparatus 1 (step S53). When the main device 1 receives the call termination request from the telephone terminal 3 (1), it releases the communication line with the telephone terminal 3 (1) (step S54).

  On the other hand, the user of the transfer destination telephone terminal 3 (N) depresses the hold release key provided in the operation input unit 311 of the telephone terminal 3 (N) (step S55). The control unit 320 of the telephone terminal 3 (N) forms a hold release request and transmits it to the main apparatus 1 (step S56). The control unit 120 of the main apparatus 1 that has received the hold release request forms a hold release response and transmits it to the requesting telephone terminal 3 (N) (step S57). After that, the main device 1 connects the communication line with the caller party that has been put on hold between the caller and the transfer destination telephone terminal 3 (N), and the caller and the transfer destination telephone terminal 3. A call can be made with the user (N) (step S58).

  Thereafter, between the main device 1 and the transfer destination telephone terminal 3 (N), a process of adding a search mark to the call voice can be performed by the processes of steps S59 to S61. The That is, the processes in steps S59 to S61 in FIG. 14 are the same as the processes in steps S10 to S12 shown in FIG. In this example, hold / transfer is performed, but the recording of the call voice is continuously performed on the first call voice file 109. On the other hand, in the FK input file 110, since the telephone terminal used for the telephone call is the telephone terminal 3 (N), the FK input file 110 (FIG. 7) for the telephone terminal 3 (N) is formed. The FK input data corresponding to the flexible key operation is stored.

  Thereafter, when the call is finished, the same process as the process shown in steps S13 to S17 shown in FIG. 9 is performed, the communication line is released, and the call voice recording process is finished. In addition, since the FK input file 110 for each of the transfer source telephone terminal 3 (1) and the transfer destination telephone terminal 3 (N) is formed in the case of hold / transfer in this way, The FK input data of both FK input files 110 are added to the call voice file.

  FIG. 15 shows that in the processing shown in FIGS. 13 and 14, processing for adding search marks was performed on each of the transfer source telephone terminal 3 (1) and the transfer destination telephone terminal 3 (N). It is a figure for demonstrating the specific example of the process in a case. In FIG. 15, as indicated by arrows, the horizontal direction in the figure is the time axis, and the upper left corner is the incoming call response position (when the incoming call response is made). Further, in FIG. 15, in this example, there is a position (time point) at which the communication line is released by the other party (calling source) on-hook in this example, and then the recording of the call voice is finished. There is a position (time) that has been moved.

  Then, as shown in the upper left part of FIG. 15, the telephone terminal 3 (1) under the main apparatus 1 performs an off-hook operation on the incoming call, thereby performing a response operation, connecting a communication line, and making a call. Like that. When the telephone call is made, the user of the telephone terminal 3 (1) performs a call voice recording start operation at the operation time t11 and is a call part of the other party. Suppose that the flexible key FK1 is operated in order to attach a search mark indicating the above.

  In this case, at the operation time t11, the telephone terminal 3 (1) and the main device 1 cooperate to form the call voice file 109 first, and record the call voice data and the call voice file (recording the call voice). ). Further, the telephone terminal 3 (1) and the main apparatus 1 cooperate to form an FK input file 110 for the telephone terminal 3 (1) (for the telephone terminal whose extension number is 101) for flexible key operations. Corresponding FK input data is generated and recorded. In FIG. 15, since the flexible keys FK2 and FK1 are operated in the telephone terminal 3 (1) at the operation time points t12 and t13, the FK input data corresponding to the operated flexible keys at each time point. Is recorded in the FK input file 110 formed at the operation time t11.

  Thereafter, as shown in the upper left side of FIG. 15, a hold / transfer occurs, and the communication line is transferred from the telephone terminal 3 (1) having the extension number 101 to the telephone terminal 3 (N) having the extension number 210. Suppose that Then, as shown in the middle left side of FIG. 15, it is assumed that the hold is released at the transfer destination telephone terminal 3 (N) and the flexible key FK2 is operated at the operation time t21. In this case, in this case, the telephone terminal 3 (N) and the main apparatus 1 cooperate to form the FK input file 110 for the telephone terminal 3 (N) (for the telephone terminal having the extension number 210), and to flexibly FK input data is generated and recorded according to the key operation. Note that the call voice is continuously recorded in the call voice file 109 formed at the operation time t11. Of course, while the communication line is on hold, the call voice recording process can be paused, and when the hold is released, the call voice recording process can be resumed.

  In FIG. 15, since the flexible keys FK1, FK2, and FK1 are sequentially operated at the telephone terminal 3 (1) at the operation time points t22, t23, and t24, the flexible keys that are operated at the respective time points are displayed. The corresponding FK input data is formed and recorded in the FK input file 110 formed at the operation time point t21. That is, even if call voice is put on hold / transferred, it is recorded in one call voice file, and an FK input file is created for each telephone terminal subordinate to the main device 1 and added through each telephone terminal. The search mark (FK input data) adapted to be recorded is recorded.

  Thereafter, the call is terminated and, for example, an on-hook operation is performed at the caller's telephone terminal, whereby a call termination request is provided to the main apparatus 1 and the communication line is released as shown in the lower right part of FIG. The call voice recording process ends. When the recording of the call voice is completed, the call voice file 109 and the FK input file 110 are also closed. Thus, the call voice from the operation time t11 when the recording start operation shown in the upper left part of FIG. 15 is performed to the recording end time shown in the lower right part of FIG. 15 is stored in one call voice file 109. The

  Further, the three FK input data formed at the operation time points t11, t12, and t13 are stored and managed in the FK input file 110 for the telephone terminal 3 (1). Further, the four FK input data formed at the operation time points t21, t22, t23, and t24 are stored and managed in the FK input file 110 for the telephone terminal 3 (N). As a result, each of the user of the telephone terminal 3 (1) and the user of the telephone terminal 3 (N) can listen to the entire call voice recorded from the time t11. The reproduction position search process can be performed using only the added search mark (FK input data).

  The reproduction process can be performed in the same manner as described with reference to FIG. Then, for example, the user of the transfer destination telephone terminal 3 (N) adds a search mark later to the call portion between the user of the transfer source telephone terminal 3 (1) and the destination and uses it. be able to. Similarly, the user of the telephone terminal 3 (N) as the transfer source should add a search mark later to the call portion between the user of the telephone terminal 3 (N) as the transfer destination and the destination. Can do.

  The search mark added by the user of the transfer source telephone terminal 3 (1) and the user of the transfer destination telephone terminal 3 (N) is managed in a distinguishable manner, so that the user adds them. The playback position can be searched using only the search mark.

[(3) Processing related to call recording when using the conference call function]
Next, processing related to call recording when using the conference call function will be described. 16 to 18 are sequence diagrams for explaining processing related to call recording when the conference call function is used. The conference call function is different from the case of hold / transfer, and at least three parties of the other party, the phone terminal that started the call under the main device 1 and the other phone terminals of the main device 1 can talk simultaneously. Is possible.

  For this reason, the user of the telephone terminal 3 (1) subordinate to the main apparatus 1 responds to the incoming call, connects the communication line to start the call, records the call voice, and further records the call voice. The process up to calling the extension telephone to request the user of the other telephone terminal 3 (N) to participate in the call is the same as the case of the hold / transfer described with reference to FIG. Done.

  Then, the user of the telephone terminal 3 (1) holding the communication line connected to the caller places an extension telephone on the telephone terminal 3 (N) and requests participation in the telephone conference (step S51). When consent is obtained, as shown in FIG. 16, the telephone conference key provided in the operation input unit 311 of the telephone terminal 3 (1) is pressed (step S71). The control unit 320 of the telephone terminal 3 (1) forms a conference request and transmits it to the main device 1 (step S72).

  The control unit 120 of the main apparatus 1 holds the communication line with the other party of the outside line by the telephone terminal 3 (1), and between the telephone terminal 3 (1) and the telephone terminal 3 (N). Knowing that the extension communication line is connected. For this reason, the control unit 120 of the main apparatus 1 sets the telephone terminal of the outside line partner on hold, the telephone terminal 3 (1) that started the call first, and the telephone that is connected to the telephone terminal 3 (1) by extension. A communication line is connected between the three parties with the terminal 3 (N) so that they can communicate with each other. As a result, the calling party, the telephone terminal 3 (1) subordinate to the main apparatus 1, and the telephone terminal 3 (N) subordinate to the main apparatus 1 are connected to each other via the main apparatus 1. Then, a conference call is performed (step S73).

  As shown in FIG. 16, after the three parties start the conference call, as shown in FIG. 17, each user of the telephone terminals 3 (1) and 3 (N) puts a search mark. Can be added. That is, through the telephone terminal 3 (1) participating in the conference call, a search mark can be given to the call voice that is to be recorded by the processing in steps S81 to S83 in FIG. Similarly, through the telephone terminal 3 (N) participating in the conference call, a search mark can be given to the call voice that is to be recorded by the processing in steps S91 to S93 in FIG. .

  The processes in steps S81 to S83 and the processes in steps S91 to S93 shown in FIG. 17 are the same as the processes in steps S10 to S12 shown in FIG. 9 and the processes in steps S59 to S61 shown in FIG. It is processing of. When the telephone conference function is used, even when the call voice is recorded, the call voice is recorded (recorded) in the same call voice file 109 from the beginning to the end. The search mark (FK input data) is recorded in separate FK input files 110 for the telephone terminal 3 (1) and the telephone terminal 3 (N).

  Then, when the call is terminated and a call termination request is transmitted from the telephone terminal of the caller (external line partner) as shown in FIG. 18 (step S101), the main apparatus 1 transmits this request to the telephone conference. It transmits to the telephone terminal 3 (1) which is a participant (step S102), and similarly transmits to the telephone terminal 3 (N) (step S103). As a result, the communication line connected between the three parties is released (step S104), and the call voice recording process is terminated (step S105). In this embodiment, the FK input data of the FK input file 110 for the telephone terminal 3 (1) and the FK input data of the FK input file 110 for the telephone terminal 3 (N) It is added to the audio file 109 (step S106).

  19 adds search marks to the telephone terminals 3 (1) and 3 (N) used for the telephone conference under the control of the main apparatus 1 in the processes shown in FIGS. It is a figure for demonstrating the specific example of a process when the process to perform is performed. In FIG. 19, as shown by the arrows, the horizontal direction of the figure is the time axis, and as shown in the upper left corner, the telephone terminal 3 (1) or the telephone terminal 3 (N) which is a conference conference participation terminal It is assumed that the recording button of the operation input unit 311 has been operated through any of the above, and the call voice recording process has already been started. Therefore, the call voice is recorded in a predetermined call voice file 109.

  Then, through the telephone terminal 3 (1) which is a conference conference participation terminal, as shown in FIG. 19, at the operation time points t31, t32, t33, t34, t35, t36, the flexible keys FK1, FK2, FK3, Assume that FK1, FK2, and FK2 are operated. In this case, the FK input file 110 for the telephone terminal 3 (1) is formed at the time point t31, and as described with reference to FIG. 6, at each of the operation time points t31, t32, t33, t34, t35, and t36, FK input data corresponding to the operated flexible key is formed and recorded in the FK input file 110 for the telephone terminal 3 (1) formed at the operation time t31.

  Further, as shown in FIG. 19, the flexible keys FK2, FK1, and FK1, in order at the operation time points t41, t42, t43, t44, t45, t46, and t47 through the telephone terminal 3 (N) that is a conference conference participation terminal. Assume that FK3, FK2, FK1, FK3, and FK3 are operated. In this case, the FK input file 110 for the telephone terminal 3 (N) is formed at the time point t41, and as described with reference to FIG. 6, each of the operation time points t41, t42, t43, t44, t45, t46, and t47. The FK input data corresponding to the operated flexible key is formed and recorded in the FK input file 110 for the telephone terminal 3 (N) formed at the operation time t41.

  When the call ends, the communication line connected between the three parties is released, and the call voice recording process ends. Thereby, each of the user of the telephone terminal 3 (1) and the user of the telephone terminal 3 (N) can listen to the entire call voice of the call voice recorded by operating the recording button. In addition, it is possible to perform a reproduction position search process using only the search mark (FK input data) added by the user.

  In addition, the user of the telephone terminal 3 (1) and the user of the telephone terminal 3 (N) are managed so that the search marks added by each user can be distinguished from each other, so only the search mark added by the user is used. Thus, the playback position can be searched.
