First, it is assumed that the answering state is set in the initial settings (step 21) and the response message has already been recorded. Also, the receiving tape TP2 is rewound to the starting end at this time to eliminate the deviation in the recording start and end positions of the received message.

A call from the caller is received at the input terminals TI and T2 of the telephone line, and is input to the control circuit 5 via the ringer circuit 2 and ringer detection circuit 3 (step 22).
