[SR-Users] Not able to replace route_uri in contact header uri

[Daniel-Constantin Mierla]

Hello,


skipping to understand exactly the purpose of what you want to achieve,
if you want to replace the contact header uri with [username from old
Contact]@[kamailio ip]:[kamailio port] , you can try this:


if(is_present_hf("Contact")) {

  remove_hf("Contact");

  append_hf("Contact: <sip:$(ct{tobody.user})@$Ri:$Rp>\r\n)");

}


If doesn't work, let me know.


Cheers,
Daniel
