Asterisk translates the signaling methods for you via the Dialplan.

Setup your sip.conf to accept calls from your SIP phone(s), which will 
include a specific context where you wants those calls to go into the 
dialplan (extensions.conf).

That dialplan then can call any other channel type (Zap, IAX, H.323, 
SCCP, MGCP) by using the Dial application for the specific extension
you wish to dial.


I suggest you purchase the Asterisk book. You seem to be missing quite a 
few major core concepts of how Asterisk functions.
