Unity Connection Integration

[paulblakie]

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?

I have checked the interoperabiltiy portal, and there is no Unity Connection information.

Hi Paul,

Only the Mitel and Rolm PIMG units are EOS/EOL:

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:

Hello, would this be the only possible solution today?

I am looking for different options to integrate CUC with a Avaya CS1000.

You should be able to setup a SIP trunk between the CS1000 and CUCM. After that, you can make the RONA for the phones on Avaya/Nortel forward to a CTI Route Point in CUCM that send the call to CUC. This is how I have done most of my legacy integrations that are SIP capable, rather than trying to point directly to CUC or using a PIMG.

Mike,
      Do you happen to have a copy of this or a newer version? It is no longer a valid link.

Another option is to integrate it with a QSIG PRI. I have done this with an MGCP gateway running QSIG registered to CUCM and the PRI side connected to a CS1000. I don't know if it is possible to do it without CUCM. I suppose it might be possible to have a SIP integration between Unity and CME, and you could have the appropriate dial peers in CME to point the DN's down the QSIG PRI to the CS1000.
