DP (dial pulse) of the extension number sent by the worker from another extension connected to the above PBX, or from another PBX extension connected to the above PBX via a dedicated line or private line.
Or, when a call is received by a PB (button button) signal, if this is detected, the response is made by closing the direct current circuit of the telephone line, and then a specific voice for confirming the voice of the call is sent to the telephone line. When the worker receives the PB double signal of the worker's extension number sent out by the worker, it must be decoded, the telephone line is once disconnected, the line is captured again, and the decoded extension number is automatically dialed to the worker's side. A series of operations is performed in which the extension is called, and after the worker's extension answers, a specific voice for confirming the voice of the first call is sent to the telephone line.

[Function] As described above, if the device of the present invention is used, the call confirmation test can be carried out.
It is possible to achieve almost the same effect as the conventional case in which workers are placed at both ends of the communication line. The device of the present invention is inexpensive because it can be easily manufactured using parts that have already been reprinted in large numbers, and the effect of reducing the number of workers is extremely large.
