<div>Let me add some more details which I noticed.<br>
<br>
</div>
As i explained in previous post in the same subject, we
receive ACK without to tag from one UA, since it will not
match any dialog, I tried to route it to destination with
topology_hiding but topology hiding used different branch tag
than the 200 OK received (It only replaced .0 with .2). I
think this is happening because I am also using drouting
module and UAC which use branches.<br>
<br>
</div>
I can post trace also if someone wants to have a look.<br>

<div>I am using opensips 2.1 with topology_hiding
module. I have an issue only with one SIP endpoint.
This endpoint sends Ack message (after 200 OK to
Invite) without any to tag because of that it is not
matching with In dialog request section.<br>
<br>
</div>
Can a UA send ACK without to tag?...If yes any way I can
match it with ongoing dialog?<span><font color="#888888"><br>
