[SR-Users] PRACK with UDP to TCP translation send over wrong protocol

Hello,
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.
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).
Cheers,
Daniel
