Problem with SIP BYE message
sip, voip
Solution
You might want to check what does the value of warning header says. There is some custom message "Noisy feedback tells"... this is very application specific. Request Timeout messages are usually emulated by stack when transaction timeout is expired. That might mean your BYE request to 174.37.45.134:5060 could not reach destination. This can also be the case when original BYE request is malformed and other party ignores it.
Have you tried debugging your server locally with SIPp? You can also run Ethereal (Wireshark) to check your traffic.
Problem
I am writing a SIP server, and I have it taking calls and then connecting them to a voip phone, the problem is when you hang up the voip phone, there's something wrong with the forwarding of the BYE message where my cell phone doesn't end the call. Here is the SIP message log (I replaced my server's phone number with 1234 and my cell phone's phone number with 5678, my server's IP has been replaced with x's and my voip phone's IP has been replaced with y's) -
