PROBLEM TO BE SOLVED: To eliminate the need for confirming a speech end and redialing by informing it to a caller that a speech is unable at present when a call is received from another slave set by a busy slave set and allowing the slave set to the number automatically when the speech is available. SOLUTION: A control section 4 detects that a control channel having been received via a radio transmission reception section 2 is not available and displays that a speech is not available at present to a display section 3. In this case, when an operation section 6 of the slave set makes dialing, the control section 4 registers a destination number of the call to a memory section 8 and when a speech made by another slave set is finished, a master set restarts transmission of a control channel and the slave set receives the control channel via an antenna 1 and the radio transmission/reception section 2. Then an automatic dial section 7 automatically makes dialing to the destination number registered in the memory section 8 and informs the user it by a different call tone from a usual call reception tone that the user is called. |
