Abstract: PURPOSE:To reduce the time of remote listening and to decrease the talking charge by detecting a remote control signal sent by a caller selectively, and selecting a voice signal and a video signal stored in a reception message storage section selectively to a telephone line. CONSTITUTION:When a call signal is inputted, an incoming call detection section 18 detects it to close the telephone line. Then a replay message transmission section 19 sends a reply message to a caller. Then when only the voice signal is desired to be listened by remote control, the operator sends a remote signal listened remotely for the voice only during reply message transmission. An automatic answering telephone control section 27 controls a reception message reproduction section 21 and a reception message transmission switch 30 and only the video signal is reproduced by the value stored in a start position storage section 31 counted by a rotational frequency count section 27a at the time of recording. Moreover, when only the video signal is desired to be reproduced, the operator sends a remote control signal to view only the video remotely to start the operation during the transmission of the reply message.
