ABSTRACT:
A telephone ringing adapter has a preset number of ringing tones of a calling signal applied from a telephone call diverting device or the like. When the incoming ringing number coincides with the preset number, a relay is energized so that the calling signal is applied to a conventional telephone answering device which is connected to the adapter to comprise a loop circuit and take a message from the calling party. After the hang-up of the calling party, the relay is released and it returns to standby mode for the next call. So, even when the final call diverted party doesn't answer the call, it is possible for a general telephone answering device to operate the automatic answering and recording function for the calling party after the preset number of calling signals.
