PROBLEM TO BE SOLVED: To enable only a specific slave set being an original terminating destination to reproduce and output a voice message which is recorded by an automatic recording function without requiring complicated operation, etc. SOLUTION: A master set 4 stores the telephone number of an originator which may possibly be terminated at each slave set in a RAM 19 for ever slave unit and then urges the originator to send a voice message if no answer is received from each slave set and the set 4 in a terminating mode. The voice message sent from the originator is stored in the corresponding storage area of the RAM 19 only when the telephone number is received from the originator in the terminating mode and also it is decided that the telephone number is stored in the RAM 19. Then the slave sets included in a radio connectable communication range are always searched, and the voice message stored in the RAM 19 is sent to every slave set included in the said communication range in consideration of the storage area of the message. |
