I'm performing a pilot with Cisco CUCM 6.1.3 and Exchange 2010 as UM solution.
Currently I'm able to send calls to Exchange a leave voice mail from an Internal IP Phone and also the MWI goes on, but when I try to make the same test calling from an external number the call is dropped on the gateway.
Doeas anybady as a similar situation and suggestion.
- Cisco 2811 Voice Gateway registered in MGCP with the CallManager
- Cisco CUMC 6.1.3b
