MWI over QSIG PRI

We tried to accomplish QSIG integration over PRI's between CS1K and Cisco. Everything works fine except the MWI relay over QSIG across PRI's. Is there something that i missing in the integration piece. Here is the call flow. Our CS1Ks are at Release 7.65 with SP8 and CUCM at 10.5. What i am trying to accomplish is move the mailboxes for avaya phone to unity mailbox and be able to provide mwi to avaya phone from unity connection.

Avaya phone--->CS1K--->QSIG PRI--->MGCP Gateway--->CUCM--->SIP--->Unity Connection

attached is the debug from the mgcp gateway. Our PBX tech has set up QMWI Integer Coding for the MWI and he complains that he doesn't see a message request rather a normal call for MWI. I believe that is norm and MWI is provided by Unity based on the bearer capability.

Re: MWI over QSIG PRI

Hi -

 

Take a look at the Interoperability docs.  The link below refers to a Nortel QSIG to CUCM integration.  The versions referenced are older but might give you some direction.
