Ok, my problem is exactly how I can do that?
How can I say to asterisk "this port is connected to the world and the
other is connected to my office telephon switch" (this is my main
problem, I see something about groups but I'm not sure about the right
configuration...)?
How I can forward a call? It's simply an extension.conf rule?
When I make the forward in this way (with extension.conf rule) asterisk
make some work or is a simple passthrough from interfaces?
I need that calls "from PRI to PRI" don't load the computer.
I want to use all CPU to (future) SIP calls.

Thank you for your reply.
