する電話機。 A telephone equipped with a dial pulse generation circuit and a multi-frequency signal generation circuit, further comprising a response signal detection circuit that detects a preset response signal from a called party after a dial signal from the dial pulse generation circuit is sent, It is characterized by having a switching means that automatically switches transmission of the dial signal from the dial pulse generation circuit to the multifrequency signal generation circuit in response to a response signal detection signal from the signal detection circuit, and restores the transmission to the original state after the end of the call. A telephone set.
