SIP Trunking Trace

[texmatlock]

I am seeing the following every few minutes. This SIP trunk is having problems. Does anyone know what all this means?

Why don't you give us a general overview of the situation/setup, going straight into a trace makes it hard to picture what you have got

This is an IPO 8. It has SIP trunks to 2 different BCM 450's.
Also SCN to 3 other IPOs.
The SIP trunk to one of the BCM's is good. The H323's are all up.
But the SIP trunk in question, which is shown in the trace, is having problems. Calls can make it into the IPO from the BCM, but not the other way around.
Also calls placed from the BCM to one of the other IPO's through this IPO do not make it.

The trace activity above is indicative of something that is not user generated. Its appearing in the trace every few minutes even when no one is attempting to use that trunk.

Post traces of the calls described above failing, that will indicate the issue better than the trace provided
