Incoming gateway calls in a CAC restricted branch to a local branch office subscriber (no CAC restriction on this call as both gateway and subscriber are in the same CAC group) are forwarded to a central Voice Mail Server located in the data center.
Figure 1. Enhanced CAC Restricted Subscriber Rerouting for Endpoints
As the Voice Mail Server is administered as a trunk, endpoint rerouting would be activated for the call to Voice Mail. If all routes for endpoint rerouting are exhausted, enhanced CAC restricted subscriber rerouting will be tried. Calls are tied in the Lotus Sametime Unified Telephony.
