I'm trying hard to succeed with NAT without STUN. I have seen the default ser.cfg provided in the mediaproxy module (0.8.14 as well as 0.9). To me it seems as if the use_media_proxy() function is called for all calls and not for NATed only (media is relayed for all calls) because the setflag(2) set during registration is never checked anywhere.. Am I right in thinking so? Please help.
