I am trying to figure out a way in Unity Connection via Routing rules or whatever, to route calls to a site-specific Opening greeting if no mailbox extension is matched. For example. User A in Mexico leaves the company. Since Unity Connection is AD integrated, once his AD account is deactivated, it will eventually expire in Connection and drop his mailbox out of Unity. However, User A's phone and extension still exist in UCM and is set to roll to VM for CFNA. I want to be able to define a range of extensions that are local to that site, and send them to a different Call Handler that is in Spanish instead of matching the default Opening Greeting.
It seems like it would be simple to do via Forward Routing Rules but the combinations I have tested seem to grab all the calls or none of them, despite the range of numbers I have defined. Has anyone set this up?
