Abstract

PURPOSE:To confirm there is a message without providing a special hardware to a telephone set, etc., by sending a special dial tone from a special dial tone source at the calling time of the telephone set.

The central control unit 4 reads information concerning the telephone set 1 from a main storage device 5 and investigates whether there is a message to the telephone set 1 or not. When there is the message, the central control unit 4 controls a channel switch 3, connects the extension circuit 2 and a special dial tone source 6, causes the telephone set 1 to listen to a special dial tone and after that, executes a dial figure reception preparation. The operator of the telephone set 1 listens to the special dial tone and executes an operation to listen to the message or after a call, etc., with the other telephone set is finished, the operator executes the operation to listen to the message.
