[SR-Users] Kamailio NAT traversal

[Spencer Thomason]

Hello,
I'd like to use Kamailio in from of FreeSWITCH to handle NAT traversal.  Is there a way I can allow freeswitch to handle all auth but store the registration in usrloc as I need to send an options ping to the endpoints?  

My thought is something like this:

natted endpoint -> kamailio -> freeswitch
If the response is 200OK, save the registration.

Thanks,
Spencer
