DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a LAN telephone system in which an information processing apparatus such as a personal computer (PC) is used to call and talk to a partner via a local area network (LAN).

[0002]

2. Description of the Related Art In recent years, the so-called CTI (Computer Telephony), which integrates a computer and a telephone, that is, creates a new value by integrating functions of a computer and telephone communication such as telephone / fax.
(Integration) technology is attracting attention. The technology of CTI is, for example, a customer database (D
B) It is possible to enhance the function of the call center and improve customer satisfaction by cooperating with the system, or realize a message environment integrating voice, fax, and e-mail by cooperating with the mail system. In addition, this technology makes it possible to automate telephone response and to support the operation of making a telephone call, and is expected to greatly improve the operation efficiency by utilizing the technology.

FIG. 1 shows a CTI using this CTI technique.
FIG. 2 is a diagram illustrating a configuration example of a client system. CTI
In the client system, as shown in the figure, telephones 5, 6 are connected to client PCs 1, 2 via dedicated adapters 3, 4.
Connect. Then, the dedicated application is installed in the client PCs 1 and 2. Thereby, LA
When an audio signal is transmitted on N7, a call can be made between the client 1 and the client 2 or via a client-CTI server (not shown) as shown by a route indicated by a broken line 8. With such a configuration, LA as described above is used.
It is possible to realize an N telephone function or an automatic telephone response, and a support function for making a telephone call. In a general telephone, as shown by a route indicated by a broken line 11, a telephone 5, an adapter 3, and a PBX (Private Branch E).
xchange) 9 to connect to the telephone line 10 to make a call.

[0004] In this type of CTI client system, a push-button telephone connected to a personal computer (PC) is used as a normal telephone, such as making a call to a partner, making a voice call with the partner, or receiving a call from the partner. It is used as a voice input / output device for recording / reproducing voice mail. Therefore, it is not recognized by the PC which push button of the push button telephone has been pressed, and when using a LAN telephone, the caller inputs the other party's IP address to the PC from the keyboard and then presses the call button. Press to do it. PC
When the call button is pressed, the other party is called by the input IP address, and a call on the LAN is enabled.

[0005]

Conventionally, when a call is made using a LAN telephone in a CTI client system, the caller inputs the IP address of the other party from a keyboard to a P-key.
An operation of inputting to C and then pressing a call button was required. For this reason, in a LAN telephone, it is not possible to make a call by lifting the handset and pressing a push button like a normal telephone. For a caller who has been accustomed to a normal telephone for a long time, a LAN telephone through a PC is required. Has a problem that operability is poor and it is difficult to use.

Accordingly, an object of the present invention is to provide an LA having good operability.
An N telephone system is provided.

[0007]

An object of the present invention is to convert an analog push button signal from a push button telephone into a digital push button signal, recognize the digital push button signal and convert it into an IP address. Local area network (L
This is achieved by a LAN telephone system configured to call and talk to the other party via AN). With this configuration, it is possible for an information processing apparatus such as a PC connected to the push-button telephone to recognize which push button of the push-button telephone is pressed. This makes it possible to make the outgoing operation at the time of the LAN telephone equivalent to the general telephone operation, and to save the trouble of inputting the IP address to the PC as in the related art.

[0008] An information processing apparatus according to the present invention comprises a push button signal recognizing section for recognizing a digital push button signal obtained by converting an analog push button signal of a push button telephone, and the push button signal recognizing section. The recognized digital push button signal to I
An IP address conversion unit for converting to a P address,
L according to the IP address converted by the address conversion unit
And a transmission processing unit that calls the other party via the AN.

[0009] An adapter is connected between the information processing apparatus and the push button telephone.
A first switching unit that switches the connection with the push-button telephone from the telephone line side to the power supply side, a second switching unit that switches the connection with the information processing device from the telephone line side to the telephone side,
An AD conversion circuit for converting an analog push button signal from the push button telephone input via the first and second switching units into a digital push button signal, and a decoding circuit for decoding an output of the AD conversion circuit. It is comprised including. Such an adapter can be built in the information processing device. As described above, according to the present invention, the operability of the LAN telephone system can be improved by a simple method.

[0010]

FIG. 2 is a diagram showing one embodiment of a LAN telephone system according to the present invention. In this embodiment, as shown in the figure, a push-button telephone set 20 and a telephone line (analog two-wire type) 21 are switchably connected to a personal computer (PC) 40 via an adapter 30, and the PC 40 is connected to a LAN 50. Have been. The adapter 30 includes a speech IC 31, switching units 32 and 33, and a power supply 3.
4, an AD conversion circuit 35 and a decoding circuit 36 are provided. The PC 40 also includes a push button signal recognition unit 41,
It comprises an IP address conversion unit 42, a transmission processing unit 43, a voice processing unit 44, and a LAN board 45.

In the system configured as described above,
When the LAN telephone is used, the switching unit 32 recognizes the push button signal from the push button telephone 20 without sending it to the telephone line 21 without transmitting the signal to the PC 40.
The connection with 40 is switched to the telephone 20 side. Further, the switching unit 33 switches the connection with the telephone 20 to the power supply 34 side. This is because the push-button telephone 20 is not connected to the telephone line 21,
This is because power is supplied to the telephone to ensure the operation of the telephone.

In this state, when the receiver of the push-button telephone set 20 is picked up and the push button is pressed, the analog push-button signal is transmitted to the telephone interface 22.
(Analog two-wire system), input to the AD conversion circuit 35 via the switching unit 33, the switching unit 32, and the speech IC31. The AD conversion circuit 35 converts the input analog push button signal into a digital push button signal,
Output to the decoding circuit 36. The decoding circuit 36 decodes the input digital push button signal so that the signal can be recognized by the PC 40, and outputs the signal to the PC 40 via the PC interface 37. The push button signal recognizing unit 41 of the PC 40 recognizes the inputted digital push button signal after decoding conversion and outputs the result to the IP address converting unit 42. IP address converter 42
Converts to an IP address according to the recognized combination of push button signals. The transmission processing unit 43 determines the other party based on the IP address, and
After calling the other party via the LAN 5 and the LAN 50, a LAN call is started through the voice processing unit 44.

As described above, according to the present invention, in the CTI client system, the caller operates the push-button telephone 2
When the push button 0 is pressed, the PC recognizes the push button signal, converts the signal into an IP address, and performs a calling process. Therefore, the calling of the LAN phone can be performed in the same manner as a normal phone. This has the advantage that outgoing LAN calls can be operated quickly and easily using a push-button telephone. Also, even a person unfamiliar with a PC can easily make a LAN telephone call.

[0014]

According to the present invention, a LAN telephone system with good operability can be obtained.
