Let me add some more details which I noticed.
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
I can post trace also if someone wants to have a look.
