(2) When a proxy response is made by another telephone,
If the telephone number of the receiving telephone is unknown, it may not be possible to determine whether or not to respond, or even if a response is made, there may be inconvenience in subsequent treatment due to differences in the department in charge.

(3) When the incoming telephone number display board is provided, the machine cost and the construction cost for it are required, and it may happen that a place easy to see cannot be obtained.

The present invention is intended to solve such a problem.

[0016]

In order to solve the above problems, the present invention returns an incoming call response signal when an incoming call response signal from a connecting device is not present in response to an incoming call response signal from a connection device. Do not store the telephone number of the called telephone in the main device, and the connected device should issue a visible / audible signal to display the incoming call for a proxy response, recognize the visible / audible display, and try a proxy response. When a person who makes a call from a non-incoming telephone operates a specific key or dials a specific code, the main unit receives it via a connection device (connection device selected by calling) different from the above. By this, the main unit sends the previously stored telephone number to the calling non-incoming telephone through the separate connecting unit and displays the telephone number on its display. .

When there are a plurality of unanswered incoming calls, a plurality of telephone numbers are simultaneously displayed on the display unit of the non-incoming telephone, or a plurality of telephone numbers are sequentially displayed by roll-up and roll-down, and the substitute answer is displayed. It was designed to be used for flights.
