Hi Ali,

sure, its always better to write your own config file that you full 
understood, than base it on some templates. You could start with the default 
config that is delivered with the server.

There is no need to recompile, the nathelper/ mediaproxy modules are installed 
by default. But why do you think you need this modules at all? If you just 
want to connect to PSTN, then there is no need for this modules. If you want 
to use this modules, you need additional software as stated in the module 
documentation.

You just need to rewrite the domain part of the R-URI to the IP of the 
gateway, and send your message out with t_relay. You can do the rewriting 
with pseudo-variables or the rewritehost function.
