Re: [SR-Users] Issue with end to end MESSAGE over TCP

Hi Daniel, Thanks for your reply. I'm not really familiar with the scripts of Kamailio. I copied some sample cfg file from google. From the script, I did not find any routing logics for MESSAGE. However, end to end MESSAGE over UDP is successful, but over TCP is not. Any special routing logic for MESSAGE over tcp? Thanks again.

Using location records (lookup("location"))? Cheers, Daniel On 22/12/15 03:48, Thierry Luo wrote: Anybody give some hints on this? Thanks.

UA registration over TCP and presence flow (PUBLISH/NOTIFY) are all fine. But MESSAGE from one UA to another is UA over TCP is always not successful. I captured the sip flow from the server, and found that at the final hop from Proxy to terminating UA, the Kamailio server send the MESSAGE over udp, regardless of the fact that UAs were registered over TCP. What is the problem maybe? Attached is the cfg file. Thanks.
