Hello,
are you using topoh module?
A pcap with all sip messages part of the dialog, from the initial INVITE to the last BYE transaction would be important to have in order to investigate how the headers are changed.
Cheers, Daniel

Hi All,
I am a new user of kamailio. We have setup a kamilio server with RTP proxy. Most of the features are working fine except BYE.
Say User A and B are registered in kamailio server. A (caller) connected to B(called), call established.
- If Caller (A) disconnects the call, everything goes fine. B gets
disconnected and call releases.
- But if Called party (B) disconnects the call, A never gets
disconnected. I checked trace as well, in this case caller (A) gets a BYE with B's callid. So A rejects call with "481 call leg transaction doesn't exists".
Basically A party and B party has separate dialog established with Kamilio. So they have two separate callids . All messages are exchanged correctly. Only when B party disconnects call, kamailio sends BYE to A party with B party callid.
Please help me to resolve this issue. Do let me know if any more information required.
