Abstract
An automatic telephone answering apparatus includes tape recorder sections for outputting a speech message through a telephone line, and for recording and reproducing a speech signal through the telephone line, a controller for setting the tape recorder sections in predetermined modes, and a decoder for decoding a remote control signal received through the telephone line and supplying a decoded remote control signal to the controller. A muting circuit between a telephone line interface and the tape recorder sections blocks remote control signals from being recorded, in response to a timing signal generated by a DTMF receiver in the decoder.
