<p class=MsoNormal>Hi All,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>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. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Say User A and B are registered in kamailio server. A
(caller) connected to B(called), call established. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>1. If Caller (A) disconnects the call, everything goes
fine. B gets disconnected and call releases.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>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".<o:p></o:p></p>
<p class=MsoNormal>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.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Please help me to resolve this issue. Do let me know if any
more information required.<o:p></o:p></p>
