Asterisk server to server configuration?

Hi guys,

I want to connect my asterisk server to another server so that i can call the extensions under that server and vice versa using IAX or SIP.
please suggest some documents or your knowledge.

Thank you

search the wiki at voip-info.org/ for “Dual Servers” and you’ll find Asterisk trunking via IAX2 info. i should be all you need.
