Hi guys,

I want to leave messages on our unity box.   I have already converted a
couple 7940s to SIP, but I can't give them out to our users because I don't
want to have to deal with two voicemail systems.

we have licenses for all our users on unity as is.    we're about to buy a
bunch more 7940s, but I don't want to cause they're expensive.     I'd
rather buy a cheaper SIP phone and have it rollover to the unity vm.

You can run a SIP image on a 7940. Asterisk at home has pretty good
support for it. Check the voip-info.org wiki for instructions on
switching the firmware.

Hopefully that will take a step out of the plan -- you could 
completely ditch your Cisco system :)
