I am seeing the following issue
One of OpenSIPS users makes an outbound call through a SIP carrier. This
gets sent to my OpenSIPS B2BUA which then sends it to the SIP carrier. The
calls length makes it to 30 minutes and then it is killed.
I see that the SIP carrier at around the 30 minute mark is sending an
UPDATE message to the client but for some reason when the OpenSIPS B2BUA
sees this UPDATE message it doesn't think it is apart of the current
dialog. So then the SIP carrier sends a BYE because it never got a reply
back for the UPDATE. The OpenSIPS B2BUA has no problem recognizing the BYE
message as being apart of the Dialog and sends this over to the OpenSIPS
user. Am I doing something wrong?
Here is the NGREP

Here is what I see in the syslog

So because the logic doesn't think the UPDATE message is apart of the
dialog it goes through my main route{} logic.
Any clues as to why this might be happening?
