* [c0f25f7] :
Added Re-INVITE in-dialog pinging support
Controlled via the new "R" and "r" flags available to create_dialog() as well as the new reinvite_ping_interval module param
Work still in progress :
- Properly handle late negociation between endpoints
- Ensure SDP persistency ( DB and BIN replication )
- <span style="background-color:rgb(255,229,153)">Ensure compatibility with topology hiding ( currently the Contact header will be bogus when doing TH )</span>
- Whitelist or blacklist logic ( terminate call for 481 and 408 timeout, or terminate call for anything else other than 200 and 491 )
- Extensive testing needed for race conditions specified in rfc 5407

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