That's a feature I've also been wanting - it'd be really nice to be able
to do SIP VM notifications when the voicemail box is on another server.

I do something simillar, I use asterisk as a voicemail server for our
IP-Centrex, basically I have written an application that sends SIP notify
message to the centrex when a voicemail has been left or retrieved. I
trigger the app with parameters using the voicemail externnotify feature.
