Yup, it works. I took a copy of voi to our local Nortel distributor's 
office and showed their engineers how their phones can be used without 
their call server.

Honestly, I'm not sure if chan_unistim makes much sense.
a) The phones aren't cheap - over here they cost as much as Cisco 7940's.
b) Nortel is already going to SIP. Their latest switches all support 
SIP. I guess in the end they might produce firmware to upgrade the i2004 
to SIP.
