    <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>
    <p>Cheers,<br>
      Daniel<br>
