Get ‘500 Internal Server Error’ during SIP INVITE - cause 44



Have you ever seen anything like this before?  It usually works, but intermittently, we see calls get rejected.  It somehow seems related to high loads on the router.  We reduced the occurrences by changing our code to throttle the number of SIP INVITEs we send, but this doesn’t scale well.  Once it occurs, the only way to clean it up is to do a shut/no shut on the voice-port associated to SIP INVITE.




Any suggestions on how we can proceed to debug this issue?

Since it appears you are a Cisco Employee, my recommendation is that you use the many internal resource available to you (including, but not limited to) , like TAC access, internal forums, team leaders, etc.


This not to give the casual reader, the impression that the best source of support at Cisco is a customer's public forum.
