PROBLEM TO BE SOLVED: To provide an automatic answering function for each slave unit in a master slave unit provided with the automatic answering function. SOLUTION: When absence mode setting information and slave unit sub address information wirelessly transmitted from the slave unit are received, a CPU 8 registers the received information inside a memory 10 as absence information for the respective slave units and realizes the automatic answering function for a plurality of the slave units by managing the absence information. When any slave unit subjected to absence registration and receiving an incoming call exists, the CPU 8 detects the sub address information, refers to the absence registration information registered in the memory 10, and outputs a call setting request to an I interface control section 3 when the sub address information is coincident with the slave unit sub address registered in the absence registration. Then a speech path is established, an absence response message stored in the memory 10 in advance is read and outputted to the I interface control section 3, and the telephone set informs a caller side about the fact of absence. When receiving a message voice signal, the telephone set stores the signal to a storage area set in a memory 9 by each slave unit sub address.
