Abstract

PURPOSE:To avoid trouble of a caller to make repetitive phone call by allowing the caller to record a message in a voice storage section when a slave set is at the outside of reach of a radio wave from a master set and the talking between the master set and the slave set is not available and calling the slave set for each prescribed time by a slave set call management section. CONSTITUTION:When a slave set 15 is at the outside of a reach of a radio wave from a master set 14, since the slave set 15 cannot receive a radio wave, the slave set 15 cannot send a reply signal and the master set 14 cannot receive a reply reception signal even after lapse of a prescribed time. In this case, the control section 7 discriminates it that the slave set 15 is resident at the outside of a reach of radio wave reception, a voice storage section 16 records a message of a caller and informs the presence of the message to a slave set call management section 17. The slave set call management section 17 receiving the notice requests the control section 7 to call the slave set 15 for each prescribed time. The control section 7 uses a cordless radio section 5 to convert a speech request signal between the master set and the slave set into a radio signal depending on the request and outputs the signal via an antenna 6.
