Cannot receive or make external calls

Hello, I am doing an asterisk project for senior design and was running into trouble calling this phone or calling out. I finally go an IP phone active, IP trunk online, and IP trunk registered.

I can dial numbers on the softphone to setup the greeting message and what not so that works (i havent tried calling other phones since there are none).

How do i get this phone to dial out or receive calls? I have setup default outbound/inbound rules.

Please help!
