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.
1. If Caller (A) disconnects the call, everything goes fine. B gets disconnected and call releases.
2. 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.
