How you like to make calls ?? you?re use a SIP account from voip provider or you use FXS interfaces on asterisk server ??

For each one have confiugration parameters.
I recommend to you a reading on this website: http://www.voip-info.org/wiki-Asterisk have some examples of how to use some voip providers and documentations
