Everything you want to do is possible with the default configuration.
Just enable all configuration parts with "fix_nated_contact" and fix_nated_register". This will enable NAT traversal for SIP. Depeing if you want to relay media or not just enable/disable the "force_rtpproxy" calls.

Hi All,
I'm building a video conference system with the kamailio and the video AS. The network is as below:
UAC(behind NAT) ------ kamailio(public IP) ------ AS (public IP)
I have setup the basic kamailio and the SIP signaling can reach the AS and the call can be established. Now the time to setup the NAT traveral since the UACs are behind the NAT.
Since it's video scenario, I don't want the kamailio as the RTPproxy so try to use the NAT_Traversal module.
From the module doc, NAT_Traversal needs the Dialog module as well. Have no idea on how to load these two modules and the route config required although have readed the module docs. Wondering if someone can help on the config for this scenario?
All call with $rU=="0216666" is forwarded to the video AS as the route[CONF].
Thanks in advance!
Thanks, Kevin
Below is the current config of the kamailio server:
