[cisco-voip] QSIG MWI not working after upgrade to 7.1.3

[STEVEN CASPER]

 We have been using a Call Manager with Unity and now Unity Connection QSIG integration to Nortel PBXs for several years now. In preparation to upgrading to Call Manager 7.1.3bsu2 we upgraded our lab from 6.1.3b. All went well until we tested MWI functionality. SCCP phones work fine but the Nortel MWI does not. Downgraded back to 6.1.3b and all returned to normal. 
 
  The release notes reference the Multiple Tenant MWI Service Parameter (CSCsx96370) but it was set to true on rls 6 and is still true after the upgrade. There is also a note regarding QSIG PRI and SIP trunks but our integration is SCCP. I have not had a chance to further troubleshoot  but wanted to see if anyone else had run across this.
 
Thanks
Steve
