<div>I sent the wrong trace with the added transport=tcp test.
Yes we tried to add the transport=tcp on config to overcome
this issue but it was not resolved. I will contact the
provider to ask them to add the transport on their 183 and I
believe it will resolve the issue.</div>
<div>In case they cannot do this is there an alternative to

<p>you have the flexibility to set the transport to $du or $ru and
then relay. Or look at tm module, there are functions that can
enforce a specific transport layer. Solutions can be made in
config, but the best would be that the provider fixes it,
otherwise you have to make a more complex config file to figure
out if you have to enforce the transport manually or not, assuming
you route calls to other endpoints that set the proper transport
value.<br>

<p>Hello,</p>
<p>the contact of the 183 has no transport parameter, which
means it is the default one, respectively UDP. If the
Provider wants traffic over TCP, the contact has to be
with that transport parameter.<br>
</p>
<p>I see that incoming PRACK has R-URI without transport
parameter, but the one to be forwarded has a malformed
version where transport=tcp is misplaced, probably due to
a wrong config operation. If you do it in kamailio.cfg,
you have to append ";transport=tcp" to $ru (whole r-uri),
not to $rU (only user part of r-uri).</p>

<div>Hello,</div>
<div><br>
</div>
<div>We have the following setup and I am having
trouble passing the PRACK with correct protocol to
the provider.</div>
<div><br>
</div>
<div>UAC (OverTLS) ->(UDP)Kamailio1 (UDP)->
(UDP)Kamailio2 (TCP)-> (TCP)Provider</div>
<div><br>
</div>
<div>UAC : 10.2.1.160 NATED to <a href="http://50.50.50.50:5065/" target="_blank">100.100.100.61</a> (TLS)</div>
<div>Kamailio1 Sockets: <a href="http://170.170.170.210:5061/" target="_blank">50.50.50.210:5061</a> (TLS),<a href="http://170.170.170.210:5060/" target="_blank">50.50.50.210:5060</a> (UDP)<br>
</div>
<div>Kamailio2 Sockets: 50.50.50.182<a href="http://170.170.170.170:5060/" target="_blank">:5060</a> (UDP)
50.50.50.182<a href="http://170.170.170.170:5060/" target="_blank">:5080</a> (TCP)</div>
<div>Provider: <a href="http://200.200.200.193:5060/" target="_blank">200.200.200.209:5060</a> (TCP)</div>
<div><br>
</div>
<div>We use dispatcher on Kamailio1 & Kamailio2</div>
<div>The invite goes fine from UCA up to the
provider and the provider responses arrive to UAC
fine.</div>
<div>The PRACK from UAC to kamailio1 goes fine to
Kamaili02 but, Kamailio2 uses the UDP socket to
send to the provider so the PRACK does not
arrive to the provider and the call is canceled.</div>
<div>If the provider is on UDP everything works
fine.<br>
</div>
<div><br>
</div>
<div>Below I have the trace. What should I look for
in the config to resolve this wrong
protocol/socket on the PRACK?<br>
