recovery on timer expiry

Unanswered Question

We get "recovery on timer expiry" from Cisco IOS debug isdn q931.

We have amended the T310 timer according to document 18659 (Call Failure to Long Distance/Mobile Destination).

However "recovery on timer expiry" problem persists.
We cannot see any difference before and after changing the T310 timer even we have changed the T310 timer to maximum value.

Have you ever experienced the same situation ?

One can look at the traces to understand exactly why, but on the other hand if all calls are working as expected, you can consider that a cosmetic issue.

My call is disconnected automatically after around 10 sec.
There is no difference even I change the T310 timer to 300000 in CUCM. (2821 voice gateway controlled by MGCP)
It seems that CUCM does not consider the new configured T310 timer parameter.

If you use MGCP, any that you configure in router doesn't matter at all.


If you want stable, predictable results, use H.323 or SIP, not MGCP.
