For the purposes of this example, refer to Figure 1–9. A caller dials Extension 1234, a local extension on System B. Extension 1234 is assigned to a coverage group programmed as an integrated VMI group (Extension 7771 with one non- local member, extension 5528) as the receiver. The user at Extension 1234 is not available and the call is directed to integrated VMI calling group 7771. The systems checks the local dial plan then the non-local dial plan for the VMI calling group member extension (5528). Using UDP routing, the system absorbs the 4 dialed digits (5528) and prepends the digits 7771 (the extension for the centralized VMS/AA at the VMS hub) then routes the call over the PRI tandem trunks to the centralized VMS/AA.
If the caller leaves a message, the centralized VMS/AA sends signals over the signalling D-channel and the Message Waiting light at extension 1234 goes on. When the user at extension 1234 dials 7771 to reach the centralized VMS/AA to retrieve messages, the same routing takes place as before and when all messages are retrieved, the centralized VMS/AA sends signals over the signalling D-channel to turn off the Message Waiting light at Extension 1234.
