[Freeswitch-users] FreeSwitch fails with Kamailio Dispatcher in front.

I've setup a Freeswitch which works when connecting devices directly to it. But with a Kamailio Dispatcher setup in front, it fails. It reports the error: 2011-09-30 08:47:04.309900 [ERR] sofia_reg.c:2136 Cannot locate any authentication credentials to complete an authentication request for realm '"10.0.1.7"' I've setup tshark on FreeSwitch now to analyze the input from both scenarios. When connected directly to FreeSwitch, which works, this is my INVITE: http://pastebin.com/p4CZJJz3 This is how the INVITE looks when it fails via Kamailio: http://pastebin.com/9AFEsuVs Can anyone help my out?
