All call with $rU=="0216666" is forwarded to the video AS as the route[CONF].
Thanks in advance!

Hi All,<BR>
<BR>
I'm building a video conference system with the kamailio and the video AS. The network is as below:<BR>
<BR>
UAC(behind NAT) ------ kamailio(public IP) ------ AS (public IP)<BR>
<BR>
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.<BR>
<BR>
Since it's video scenario, I don't want the kamailio as the RTPproxy so try to use the NAT_Traversal module.<BR>
<BR>
