Abstract

PURPOSE:To check a terminating subscriber and to grasp terminating subscriber' s information prior to the response of a terminating telephone set by allowing a guidance ring-back tone trunk to output guidance information to a terminating line when a signal detector detects an incoming to the line. CONSTITUTION:When the signal detector 1 detects an incoming to the line, a control device 6 connects a channel between the guidance ring-back tone trunk 3 kept at an idle state and the terminating line. Then, the control device 6 reads out guidance information from a storage device 2 and informs the read information to the trunk 3, which outputs the guidance information to the terminating line as a voice. Consequently, an originating subscriber can check a terminating subscriber and grasp the terminating state at the time of originating a call prior to the response of a terminating telephone set.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for transmitting a ringback tone from a switching device when a call is received on a line, and in particular, the present invention relates to a method for transmitting a ringback tone from a switching device when a call is received on a line. This invention relates to a method for sending out a ringback tone with guidance.

[Conventional technology]

When a conventional exchange performs switching connection processing, when it detects that the calling telephone picks up the handset, it requests the telephone number of the other party after completing preparations for receiving the telephone number, and receives and stores the telephone number of the other party to be connected from the calling party. Furthermore, it learns the accommodation location of the connection destination from the telephone number, checks the condition of the called party, sends a ringing signal, monitors/detects the called party's response, and connects the calling telephone and the called telephone. ing.

Among these, the ringback tone that is sent from the exchange to the calling phone from the reception of the connected party's telephone number until the called telephone responds is a constant voice signal (4001 (16 of z)), regardless of the connected party. This is a periodic repetition of the 6-ratio modulated sound leaving for 1 second and stopping for 2 seconds).

Therefore, the calling party cannot confirm the other party before the receiving telephone answers, and cannot know the state of the other party until after the receiving telephone answers.

Regarding conventional switching equipment, for example, see ``Electronic Information and Communication Handbook, edited by the Institute of Electronics, Information and Communication Engineers (1988), p.
p, 2113-2136''.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, it is not possible to confirm the caller before the incoming phone answers, so errors caused during dialing,
Even if the intended party is not being called due to a mistake in the telephone number or a change in telephone number due to moving, etc., the user will not know that the telephone number is incorrect until the called party answers. Furthermore, even when calling the intended party, the state of the other party cannot be known until the called party answers.

SUMMARY OF THE INVENTION An object of the present invention is to solve these problems and provide a method for sending a ringback tone with guidance, which allows the called party to confirm the called party and understand the state of the called party before the called party responds when making a telephone call. be.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a method for sending out a ringback tone with guidance. The controller includes a storage device for storing information and a guidance ringback tone trunk that outputs guidance information audibly, and when the signal detection device detects an incoming call to the line, the control device:
The communication path between the guidance ringback tone trunk in the idle state and the incoming line is connected, and the guidance information is read from the storage device and notified to the guidance ringback tone trunk. The feature is that the information is output as voice to the incoming line.

Further, the storage device stores the called ID indicating the called phone and guidance information in association with each other, and the signal detecting device has a function of detecting the called ID, so that the signal detecting device can detect the called ID and the guidance information. When an incoming call and its called ID are detected and notified to the control device, the control device connects a communication path between an idle guidance ringback tone trunk and the called line, and also connects the call path to the called ID from the storage device. The guidance information is read out and notified to the guidance ringback tone trunk, and the guidance ringback tone trunk is characterized in that the guidance information is outputted as voice to the incoming line.

[Function j] In the present invention, M products are stored in the storage device in association with guidance information and the callee number 10 for identifying the callee number 1i.

As a result, when the signal detection device detects an incoming call to the line and the arrival of the call and notifies the control device, the control device detects the call path between the idle guidance ringback tone trunk and the incoming line. At the same time, guidance information corresponding to the called party ID is read from the storage device and notified to the guidance ringback tone trunk, and the guidance ringback tone trunk outputs the guidance information as voice to the communication line.

Therefore, when making an li call, the caller can confirm the other party and understand the state of the other party before the called party responds. For example, if you make a mistake in dialing a phone number and are not calling the intended party, you can tell by simply hearing the ringback tone before the receiving phone answers, and even if you are calling the intended party, the receiving phone will You can tell the other party's status just by listening to the ringback tone before the other party responds.
