40 Minute call drop

[Howie74]

Good afternoon all,

I'm working with Denver, as well as all docs, and I am a little stumped here.

I have a situation where incoming calls to a customer's main number, using a modular messaging for an AA. Any calls that come in through the main number to the AA are dropped at 40 minutes - every single time.

Calls direct to a user's DID from an outside number are fine.

ACA timers are not a factor - 6 hours. There is no denial event at the time, and no other smoking gun. The MM group in Denver claims PBX, the PBX group claims it is the MM.

Any ideas here?

what about a timer on the MM trunk?

Thanks - but that's not it.

I'm running some more tests today - going to try to see in the web logs if there is a common event - nothing so far.

I've checked the timers on the trunks, but nothing there. Can you all think of another timer I might be missing?

Thanks-
Howie

Did you check the COR's outgoing trunk disconnect timer on the MM trunk group in the switch?

I did Mark - 600 minutes, but thanks - a good thought.
