ACD Calls Connected Through CUCM PRI Disconnecting

[phonebits]

I'm having some issues with calls to an ACD queue being disconnected after about a
minute when they are placed from a Cisco CUCM tied with QSIG PRI. Calls placed to the ACDN from a Nortel phone stay in the queue, hearing music and periodic RAN recordings, however the call timer does not become active until an agent answers. From a Cisco phone, or a Nortel phone on another system that is also tied into CUCM, there is also no call timer, as if the call is still ringing. (except there is music and RAN provided by the main CS1000) Any call that passes through the PRI is disconnected after about 60 seconds.

Just to clarify the situations where the disconnect occurs:

Cisco phone --> CUCM--> QSIG PRI --> CS1000

Nortel phone --> Option 61C --> QSIG PRI --> CUCM --> QSIG PRI --> CS1000

I've looked all over through the RDB for the PRI route, and can't find any timers that look like they fit the 60 second timeframe. I also can't find anything on the Cisco side of things that could be causing the problem.

Any Suggestions?

Which ACD app are you using on the Nortel side?
I use Symposium Express at 6 locations and my calls that originate on the CUCM cross a QSIG tie to the Nortel. I have not had an issue with dropped calls.

I'm just using the stock Nortel ACD. I found somewhat of a solution by adjusting the T310 timer on CUCM, but that only buys 5 minutes and the call will disconnect after that. The main issue is CUCM sees a call in the ACD queue as ringing, and not connected until an agent picks up. I'm hoping there is some way on the CS1000 side of things to change this.
