Hi Giovanni, when I suggested to disable sip.instance, really I meant in the client, since I know that linphone has an option for this. Anyway the problem is not due to your patch. If your registrar is behind a proxy, you have to enable the support for the Path header in the registrar module ( http://www.kamailio.org/docs/modules/devel/modules/registrar.html#registrar.p.use_path) otherwise Kamailio will try to send the INVITE to the contact address, regardless of tsilo. In fact I guess that with your current configuration even a "direct" INVITE is not working. Hope this helps.
