Connecting two * servers

I want to connect my two * servers, both working with a@h 1.5, in order to make calls between the extensions registered on them.
I create a sip trunk (using AMP) in one of them, but it doesn’t work.
It is the right way?
Moreover one server is connected to the PSTN and I’d likke to make calls to the pstn from the other server, is it possible?

Yes, it’s possible - in fact, it’s easy! However, i don’t know anything about AMP, i can only tell you about editing extensions.conf.

Have a look at this thread:

I’m sorry, but I didn’t read the post previously because the subject seemed different from what I was looking for.
(I know ii is boring to answer always to the same questions )
Anyway, thank you ,I’ll try it!

No worries!
