<tt>Hi, Samy!<br>
<br>
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>
<br>
Best regards,<br>
</tt>

<div dir="ltr">Hi,<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>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>
