PURPOSE:To send an automatic answering control signal from a hand set to a base unit while keeping the speaking of the hand set to a base station by providing an automatic answering control signal sending part at the slave unit and providing an automatic answering control signal receiving part at the master unit. CONSTITUTION:When a control part 21 detects an incoming call through a telephone line network interface part 22 and a switching part 28 and the function of automatic recording is set at the master unit, the interface part 22, switching part 28, voice processing part 29 and automatic recording part 33 are connected, the voice processing part 29 is activated, analog/digital conversion is performed to voice data, and voices are recorded. When that function is not set, ring back tones are rung. When operating the automatic recording function of the master unit from the hand set by the user of the hand set hearing the ring back tones while keeping the speaking through the base station, a control part 1 activates an automatic answering control signal transmission part 11 and outputs the automatic answering control signal of the master unit to a slot switching part 6 when the operation of automatic recording set is performed from an operation part 10 at the slave unit, and that signal is multiplexed to any idle slot among plural slots by a multiplexing part 5. Then, it is transmitted from a transmission part 3 as a radio signal.
