A distributed Voice Messaging System (DVMS) is disclosed. The DVMS may be deployed by organizations having small branch offices for which a conventional PBX and VMS would be prohibitively costly or have too large a capacity. Accordingly, a Message Taker system (MTS) is disclosed which communicates with a conventional PBX or key system at a branch office. The MTS is also in communication with a modified conventional central VMS through a data network such as the internet. For each branch subscriber to the messaging services of the central VMS, a voice mailbox (VMB) is provisioned at the central VMS and with their local MTS. Greetings are recorded by the branch subscriber with the central VMS in the conventional manner. These greetings are then "pushed" or transmitted, over the data network, to the branch subscriber's VMB provisioned on the MTS. Callers to the branch subscriber receiving no answer or a busy signal are forwarded to the MTS which plays the subscriber's greeting and temporarily stores the caller's recorded message. Messages received by the MTS are transmitted to the VMS over the data network, using perhaps the VPIM protocol, and deleted from the MTS's memory. Messages are retrieved by all subscribers by contacting the VMS conventional. <IMAGE> |
