There is a problem of being desired.

In order to solve the above-mentioned problems, the present invention, in an electronic switching device equipped with an automatic response test device, automatically connects the calling party to the automatic response test device when the called party cannot be connected, and performs a connected automatic response test. To provide an electronic switching device which improves telephone service by immediately sending a message response to a calling party regarding the reason why a call cannot be received at the time of making a call from the device.

Means for Solving Problem C] In order to achieve the above object, the present invention receives a specific number from the calling side, recognizes the specific number, automatically tests the status of the calling side and the called side, and then detects the incoming call. In an electronic switching device having a service analysis unit connected to an automatic response test device that outputs a response message according to the reason why a call cannot be received when connection is not possible,
If the called party cannot connect, the electronic switching device inputs the called party identification information from the service analysis unit, automatically connects to the automatic response test device, and sends the called party identification information to the automatic response test device. and an automatic response test device connection section that instructs the call destination to test the line condition and performs connection processing between the automatic response test device and the calling side, and is connected to the automatic response test device connection section. The automatic answering test device is characterized in that when a call is made, an immediate message response is sent to the caller, indicating the reason why the call cannot be received.

[For production]

The present invention automatically connects the calling side to the automatic answering test equipment by the automatic answering test equipment connection part when the called party cannot connect, and the connected automatic answering test equipment tells the reason why the call cannot be received at the time the call is made. Since an immediate message response is sent to the caller for each cause, from the caller's perspective, it becomes possible to obtain the reason for the incoming call via an instant message without having to perform the conventional complicated response test. Examples will be described below based on the drawings.
