In domain's modparam, do you have "register_myself" enabled? What if you define local domains via "alias=my_domain", does it make a difference?

My example is a REGISTER without To-TAG which has a Route header with kamailio address. If i use proxy IP on Route header , loose_route() returns false as it should. However, if i use an hostname belonging to the proxy  in the route, loose_route() returns true. I have hostnames and local ips defined in the "DOMAIN" table but it doesn't seem to be working. Which other places can local hostnames and ips be configured in order to be seen as local to loose_route() ?

Hi, Thank you for your answers. The domain parameter "register_myself" solved this issue immediately.
