<tt>Hi, Samy!<br>
<br>
Can you make sure you are not calling topology_hiding() twice on
the same request? Can you put an xlog just before each
topology_hiding() apearence in your code to make sure?<br>
<br>
Best regards,<br>
</tt>

Can you post on pastebin debugging logs related to
this call? Also, can you also post the Via headers of
the initial INVITE and for the 200 OK received by
OpenSIPS?<br>

<div dir="ltr">Hi,<br>
<br>
I'm using OpenSIPS 2.2.1 version and I'm facing a
weird situation where OpenSIPS is adding a
duplicated VIA header to the 200 OK, This only
happens when I've topology_hiding() engaged into the
call.
<div><br>
</div>
<div>The scenario is very simple; two users making
call to each other on the same OpenSIPS but with
topology_hiding(). As a consequence of this double
VIA the caller device doesn't trigger the ACK and
hence we don't get media stream established
between devices.</div>

The only difference between the two scenarios is
the function topology_hiding(); is commented
out.<br>

</div>
<div>It seems like a bug to me, can anyone guide
me here validate this. <br>
