You must add "transport=tcp" parameter to the RURI. There is a function to add 
parameters to the ruri.

If a client registers using TCP it has "transport=tcp" in the 
REGISTER "Contact" header:
  sip:user at 192.168.1.58;transport=tcp

So you could add this parameter to "Contact" header before save it in location 
table.

But I've a doubt: when client is behind NAT the "received" column stored 
in "location" table is:
  sip:user at PUBLIC_IP;transport=tcp

So I assume that it's neccesary to add also here the "transport=tcp" parameter 
but have no idea of how to do it. Suggestions? is it necessary or is it 
enought with the "transport=tcp" in "contact" field?
