ISDN Se1/0:15: Received out of order IE: 31 1 80 ?????

We have 3640s acting as voip gateways between 3 remote campuses. It appears that every call we are getting the following error on our isdn connection to our PABX (Ericsson MD110):

ISDN Se1/0:15: Received out of order IE: 31 1 80

out of order IE ignored

Most times the calls work but often thay are failing with a "switching equipment congestion".

It seems to have only happened since we upgrades IOS to 12.2-8.t5

We would need to see a full trace from Debug ISDN Q931 to determine what is happening here.

Enable the debugs, then make a call that fails. These will tell us who is clearing the call.
