<tt>Hi Ravinder,<br>
<br>
As per the trace, the ACK is properly routed (frames 17 & 18).
Also the incoming BYE (frame 19) is forwarded after a long time
(see frame 22), still there is a funny 501 reply for BYE (before
the relay) in frame 21.<br>
<br>
Could you also post somewhere the OpenSIPS logs (level 4, debug)
corresponding to processing the incoming BYE (from 19) ?<br>
<br>
Best regards,<br>

<div>Hello,<br>
i am using opensips v2.2.1 as SBC.<br>
call flow is like
caller->opensips->server->open<wbr>sips->callie.call
is established successfully but when BYE is
sent by any user it is not recognised by
topology_hiding_match() also i am not getting
any dialog related values(DLG_status,DLG_did
etc) in ACK or BYE method.<br>
<br>
here is my logic for requset handling :<br>
<br>
route[PROCESS_INVITE] {<br>

if(t_check_trans()) {<br>
drop();<br>

}<br>
<br>

<br>
xlog("L_INFO",":::::DAILOG STATUS::::

<wbr>
rtpproxy_unforce();<br>
}<br>
route("RELAY_ROUTE");<br>
}<br>
}<br>
}<br>
<br>
what is going wrong here ? is there any way to
handle this issue?<br>
