Since the PIMG is EOL, I have a Unity Connection integration question.
Is it possible to integrate Unity Connection via SIP to a Nortel CS1000 such that calls to and from voicemail will be delivered and MWI will light on the Nortel phones?

The Analog and Digital PIMG units are still available.
Unity Connection does not support a direct SIP integration to the Nortel CS1000. Unity Connection would require CUCM-SME in between the Nortel CS1000 and Unity Connection. Note that with CUCM-SME 8.5 and later, there is now the ability to create SIP normalization scripts to take care of the voicemail integration issues documented here:
