[SR-Users] Kamailio behind NAT

[Klaus Darilion]

Actually, it should work without any NAT traversal done in Asterisk, if 
Asterisk communicates never direct with the phones, but only via 
Kamailio and rtpproxy. In this case, Asterisk can use private IP 
addresses. All the near-end NAT traversal can be done in Kamailio.
