I downloaded the NAT example from
onsip.org. but when
i am trying to start ser. i am getting some error.
I think coz of mediaproxy.sock file, because i cannot
see file in my /var/run folder.
Well, you should make sure that mediaproxy is running correctly then... Ex.
netstat -nlp | grep proxy
g-)
here is my example.

fork=yes
log_stderror=no

address here
