T-Shoot SIP Trunk debug ccsip error "attribute ptime"

Jason Aarons · ‎05-27-2009

Running 3845 with 12.4(20)T with Verizon Business SIP trunk, getting intermittent reports of ghost calls, etc.

I ran a debug ccsip error and see the below, trying to understand what they mean. I understand it has to do with packetization time, not sure how/what to set it at. Saw another thread about how this error could be force calls to need to use a MTP, wondering if the intermittent ghost call is a Media Resource Exhausted error..

You'll have to post the SDP of the message to tell what's going on.

If using cucm and cube you will need both ccm sdi sdl traces and debugs in gw, debug ccsip messages,events.

in RTMT u should see media resource exhausted or no more mtp resources
