http://opensips.com.br/wiki/index.php?title=Oopensips_Nat_script_with_RTPPROXY_-_English


First of all, my english is not so good as i want, but im writing this in english too because i ever see a lot of people asking about nat problems, so if you find something wrong on my english translation please fix that.


Nat is something that need some work to understand how to use with opensips, is different from what we know on asterisk where you just need to set nat=yes and everything work fine.


I will not show how to install opensips or rtpproxy because we have other howto's here that show this, i will just show the opensips.cfg route script with a simple configuration to accept register and relay the call from a user to another over nat.

The script does not need any user created on opensips, any authentication will be accepted and if you do a restart on opensips you need to register the account again because the location information is just on the memory.


There is a lot of ways to make this, using variables and other functions, this way is simple, is for understand, you can your own implementation as you want.
