TrixBOX to Asterisk

Hi all, I recently setup Trixbox, but since I am a BSD guy I went ahead and installed Asterisk; however, it seems to be a lot harder. The config files from TrixBOX are pretty different.

What i’d like to do is have 1 SIP trunk to my provider and then 1 extension to a Cisco IP phone. How can this be done easily? I have the Trunk part down pretty well; however, i’m very confused by the extension, dial plan, and incoming rules.

Can someone help me out? I’d be willing to throw in a few bucks to someone willing to help me get thru this.
