well the story goes like this. I downloaded the new exchange server from microsoft just to test out since in this version (2010) MWI is now supported. My VOIP platform is a 2811 running c2800nm-ipvoice-mz.124-24.T.bin & CME 7.1 & my phones are 7971GEs. My voicemail is located on the exchange server and is reached via a dial-peer.
dial-peer voice 4400 voip
session protocol sipv2
session target ipv4:10.10.10.11
session transport tcp
When i use on of my phones and leave a voicemail i receive the voicemail in email and exchange sends a SIP notify, debug ccsip messages shows that it arrives on the router but then it can't find the extention to turn MWI on?

I'm not really sure what is going on here, but the docs. that i have found point to a 481 if the voiceport is not enabled for MWI. since i don't have a voice-port FXO, T1, FSO i'm not sure if that applies.
an answer would be great, but if not some insight as to what i should be looking at next would be awesome!!
