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.
