indeed, Route headers are built out of Record-Route headers found in
INVITE and 200ok.<br>
<br>
Note that Kamailio is doing by default loose routing, you may find some
devices still doing the old specs with strict-routing.<br>
<br>
When it is the case of strict routing you find Contact address in last
Route header, otherwise, with loose routing, contact address is in
Request URI and Route headers only with addresses from Record-Route.<br>
<br>
If you are involved in a scenario with strict and loose routers, then
it is a bit more complex. However Kamailio deals very well with both
separately or in a mixture.<br>
<br>
Cheers,<br>
Daniel<br>
