Abstract

PURPOSE:To restart talking immediately by accommodating a multi-function telephone set able to make holding for an extension telephone set and calling a speaker in sound from the holding extension telephone set. CONSTITUTION:When a user of a multi-function telephone set 1 makes holding while the telephone set 1 and the extension telephone set 4 are busy, a CPU 6 recognizes the holding of the multi-function telephone set 1 and uses a subscriber circuit 5 to send a holding tone representing the holding of the extension telephone set 4. When the operator of the extension telephone set 4 desires the operator of the telephone set 1, the operator of the telephone set 4 makes hooking and depresses further a specific number. Then the circuit 5 sends a voice for calling of the telephone set 1 to attain the state of voice call from the telephone set 4 to the telephone set 1. The operator of the telephone set 4 uses a speaker 2 to call the operator of the telephone set 1 in voice. When the operator of the telephone set 1 makes hooking to reach the talking state again, the processing is finished.
