Abstract

PURPOSE:To make the size small and the cost low, by managing the message of a plurality of sets of telephone in a centralized mode with a controller. CONSTITUTION:A recording button of a button telephone set 2 is depressed, an assigned extension number is dialed, a message is transmitted from a transmitter and this is recorded on a recording device circuit 7 of a controller 1. Next, when an incoming call is present at a main trunk or a PBX line, a line interface circuit 10 detects the incoming call and transmits a detection signal to a central processing circuit 5. The central processing circuit 5 discriminates if a message is present in the button telephone set 2 assigned to this incoming line. If any message is present, the circuit 5 starts the recording circuit 7 and a communication control circuit 8, and the message recorded in the recording circuit 7 is returned to a line with incoming call via a communication control circuit 8 and the interface circuit 10.
