[SR-Users] Kamailio Dispatcher fails in front of FreeSwitch, help (again).

I've asked a lot of question about Kamailio Dispatcher in front of FreeSwitch in this mailing list. So I'm sorry that I'm still "spamming", but it still fails. This is my status so far. When connecting 2 devices directly to FreeSwitch everything works. When connecting to Kamailio, some calls fails with "Timeout" and some fails with "Too many loops". This is my kamailio.cfg: http://pastebin.com/KEuZmikh When connected directly to FreeSwitch where everything works, this is how my clients are registrered in FreeSwitch: http://pastebin.com/prkjkb7g When connected to Kamailio where nothing works, this is how my clients are registrered in FreeSwitch: http://pastebin.com/b5x6NZyv 215.197.145.132 (sip.my-domain.com) is my Kamailio. pbx.my-domain.com is my FreeSwitch. 96.224.14.164 is my IP at home, where my 2 devices are from. Can anyone help me out? I'm kinda lost at this point.
