ABSTRACT:
In a telephone answering machine, when the calling party information reception unit receives calling party information, and the call detection circuit detects a receiving signal, the main control unit makes the line interface capture the communication line and generate a communication path to the calling party telephone. The main control unit then determines whether the memory has the same calling party information that has been received by the calling party information reception unit. When it has been judged in the negative, the main control unit makes the response message output unit output the first response message. When it has been judged in the affirmative, the main control unit makes the response message output unit output the second response message. Under the direction of the main control unit, the response message output unit outputs the first response message or the second response message to the calling party telephone through the communication path which is generated by the line interface 2. As the result, the telephone answering machine identifies a large amount of calling party information, records a large number of messages, and allows the called party to listen to the messages without trouble.
