System Release

Outside dial-plan routed ￿￿￿￿￿￿￿￿

PRI voice call arrives at System K and user is not available. Integrated VMI calling group provides coverage

System K: PRI dial-plan routing deletes 555, checks local dial plan. Since user is not available, call is sent to integrated VMI calling group 7771 (has VMI conversion number 6999). The system finds the VMI conversion number in the non-local dial plan. UDP routing absorbs 6999 and prepends 7771 (System L’s centralized integrated VMI calling group extension). Routes via UDP to tandem PRI trunk pool 8761.

System L: Call rings into centralized VMS/AA and calling information indicates an outside call for mailbox 5544. When the caller leaves a message, the Message Waiting light update is sent over the PRI signalling D-channel to extension 5544 on System K.
