Hi all, i would like to ask one question to all FS folks. I am really struggling against the automatic nat system of FS, where the full logic is still not really really clear and causing a lot of headheache. Where on asterisk with a simple canreinvite=no everything works fine (even between dirty nat) on FS it does not work and FS start sending RTP to provide ip address on 10.0.0.0/8 (even if there is apply-nat-acl=rfc1918.auto) . However, independently from the bugs of the automatic nat handling systems that have with the time to be noticed, discovered, fixed, etc, etc, my question is: All this method for dynamic nat detection and handling of FS, want to be an alternative to the STUN/ICE/TURN approach of VoIP standard protocol?
