PURPOSE:To attain automatic incoming call to a data terminal accommodated in a private branch of exchange except a part operated by the operator, by using a voice response storage device and a message storage device provided in a relay exchange. CONSTITUTION:In order to attain automatic incoming call of message communication from a subscriber EX1 of a private branch of exchange PBX1 to a subscriber EX2 of a private branch of exchange PBX2, the subscriber EX1 dials a specific number by using a telephone set T, which is connected to a voice response storage device V of a relay exchange TS. The subscriber EX1 designates the message arrival time with a PB dial signal and informs the extension number of the subscriber EX2 in voice. When the registration is finished, a channel device NW of the exchange TS sets a path (4) to connect a message storage device S and the subscriber EX1, and a message is transmitted from a data terminal DT and stored in the storage device S. When the message arrival time comes and the exchange PBX2 is called from the relay exchange TS, the operator OP responds and informs the extension telephone number in voice from the device V. The operator calls out the subscriber EX2 in the conventional method and receives the message by setting a path (8). |
