Abstract

PURPOSE:To form the automatic answering telephone system with simple configuration by providing a reception message memory used to store a compressed voice data signal from a receiver in the automatic answering telephone mode to the telephone set so as to reduce the memory capacity. CONSTITUTION:When a slave set 15 is resident at the outside of a radio wave arrival range of a master set 14, the slave set 15 cannot receive the radio wave and the master set 14 cannot receive a reply signal even after lapse of a prescribed time. In this case, a control section 7 discriminates that the slave set 15 is resident at the outside of the radio wave arrival, records a caller message to a voice storage section 16 and informs the presence of the message to a slave set call management section 17. The control section converts a speech request signal between the master set and the slave set with a cordless radio section 5 depending on the request and outputs the signal as a radio wave via an antenna 6. When the slave set 15 is resident within a reach of the radio wave of the master set 14, the radio wave is received through an antenna 12 of the slave set 15 and a cordless radio section 11 converts the received signal into the speech request signal between the master set and the slave set.
