PURPOSE:To provide an automatic answering function for each slave unit in a master slave unit in extension telephone sets provided with the automatic answering function. CONSTITUTION:When absence mode setting information and slave unit sub address information radio 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 the plural slave units by managing the absence information. When the slave unit whose absence is registered is present and an incoming call is present, the CPU 8 detects the sub address information, refers to absence registration information registered in the memory 10, and at the time of coincidence with a slave unit sub address in absence registration, outputs a call setting request to an I interface control part 3. Then, a speech path is established, an absence response message stored in the memory 10 beforehand is read and outputted to the I interface control part 3, a call side is informed of the effect of absence and when message voice signals are received, they are stored in a storage area set inside the memory 9 for the respective sub addresses of the respective slave units.
