We currently have a Cisco 7.1 voice system and it goes to our Exchange 2007 Unified Messaging for voice mail. We are in the process of deploying Exchange 2013 and I am trying to setup voice mail at a new pilot number to be handled by the Exchange 2013/UM environment. If I call the voice mail pilot number I am getting a fast busy at this point. When I try to search for docs on this integration I constantly get information on Cisco to Lync integration. Not Exchange 2013 UM. Here's what I've added in UCM:
-A SIP Trunk pointing to one of the Exchange 2013 Mailbox servers (all other details same as existing trunk.)
-Voice mail pilot with a new number
-Voice mail profile
-Route patter (1280)
If I use the Cisco Dialed Number Analyzer the call is routed successfully. So I don't think there' an issue of Calling Search Space or whatever. I suspect more needs to be done on the Exchange 2013 side.
Any links or advice appreciated.
