Centralized VMS/AA is implemented using the Group Calling enhancement and UDP routing. Integrated VMI calling groups are defined on the VMS hub system and each remote system.

From the user’s point of view, the routing is transparent. Users that travel between locations dial the same extension number from any location in the private network to reach the voice messaging system.

The integrated VMI calling group on the VMS hub system contains the voice messaging system ports. The integrated VMI calling groups on each remote system receive overflow, coverage, and voice mail retrieval calls and route them to the integrated VMI group on the VMS hub system.

Routing to the centralized VMS/AA is done by assigning a single non-local extension as a member of the integrated VMI calling group at each remote system sharing the centralized VMS/AA. This extension has no corresponding physical extension and is referred to as the VMI conversion number in this guide.

NOTE:

The VMI conversion number should not be published. This prevents users from dialing the VMI conversion number to retrieve messages, which can result in improper operation of the VMS/AA application.
