Hi!
AFAIS the client is buggy (or is there a NAT ALG/Firewall between client and SIP proxy?). Compare the Contact header in the 200 OK and the request URI in the ACK. They MUST be the same!!!

Thanks again Iñaki. I am attaching siptrace.txt file. I can see that there appears to be something odd with the ACKs in that they appear to be sent from my openser back to my openser in a loop until the max forwards is reached.
Thank you for your help.
Stagg Shelton.

Iñaki,
Thank you for your response. I have enabled the siptrace module in openser. The data in the mysql table only shows the trace between the carrier and openser. Can I submit a pcap file that shows all of the SIP communication that occured during the call.
Hi, you don't need to enable siptrace. Just install "ngrep" and do:
ngrep -d any -P '*' -W byline -T port 5060
