------ Start of attached email. Subject: RE: [Freeswitch-users] Outbound Gateway hang up at 30 seconds with no answer ------
I have a PCAP with a failed call. It is 100K. where can I put it or send it? Should I attach it here?
I don't understand what I am looking at. Hopefully, someone can look at it and help me out.
Thanks,
Sean

I would also advocate doing both.
1. Install sngrep, and if you don't already have them, tshark and/or tcpdump
2. Use tshark (or tcpdump) to capture SIP traffic (which normally means "anything on port 5060, in either direction"), so:
tshark -f "port 5060" -i any -w capturefile.pcap
3. Then you can use sngrep to read the file which tshark created, and at your leisure, scroll through the traffic and try to understand what happened when:
sngrep -I capturefile.pcap
sngrep is a splendid tool, but SIP is not a simple protocol, so having a capture file you can go back to later, whenever you want to, and understand a bit more about it (or answer other people's questions if they ask "well, what was the response to this, then?") is very useful.

NAT or similar related issue. let me guess called party is sending a bye to you 30 seconds after the they send the 200 OK?
they are most likely not getting the ACK for the 200 OK. look at your trance and see where the ACK is getting sent to
