First, when a call to a predetermined subscriber from a predetermined subscriber or relay line is requested to the first LC 101 in the LP 104, a call request is made to the second LC 102. At this time, when the extension state of the corresponding subscriber is busy or busy, the second LC 102 transmits the information on the above-mentioned extension status of the extension subscriber to the MP 104.

Accordingly, the MP 105 checks whether the corresponding extension subscriber is a voicemail service subscriber. As a result of the check, in the case of the voicemail service subscriber, the MP 105 requests the second LC 102 in the LP 104 to transfer the call for the voicemail service to the corresponding subscriber.

Accordingly, the second LC 102 in the LP 104 transfers the call to the representative number of the Call Forwarding Directory Nmuber (CFDN) group to the subscriber, and notifies the MP 105 of the extension. The MP 105, which has received the transfer process notification, requests a ring connection to the third LC 103.

The third LC 103 connects the ring by occupying the idle line in the group, and notifies the MP 105 of the ring connection state. Accordingly, the MP 105 controls the third LC 103 to send a ring signal to the VMS 110.

Upon receiving the transmitted ring signal, the VMS 110 transmits a response signal to the MP 105 through the third LC 103. When the MP 105 receives the response signal of the VMS 110 through the third LC 103, the MP 105 transmits subscriber information through the IOP 106. At this time, the subscriber information sent out is composed of a voice mail message indicator (M), a called party DN (or an extension subscriber DN), a CFDN representative number, and terminal information as shown in FIG. 3A.

The subscriber information configured as described above is transmitted to the I / O port 111 provided in the VMS 110. At this time, the data transmission method between the input / output processor 106 and the I / O port 111 is performed by the RS-23C method.
