Abstract

PURPOSE:To eliminate the need for the manual operation used to command to which trunk line a slave or a master set is connected by a key board to make hand-free talking between the trunk line and the slave set or the master set. CONSTITUTION:A storage circuit 22 stores in advance to which trunk line a slave set or a master set is connected. When a call comes from a trunk line 1, a connection destination command circuit 23 reads a connection destination from the storage circuit 22 to command a connection destination to a control circuit 21. Thus, no manual operation is required. Or a DTMF signal sent from the arrival of a call from the trunk line 1 is discriminated by a DTMF receiver 20 and then the connection destination command circuit 23 commands the connection destination to the control circuit 21. Thus, no manual operation is required.
