Cisco CME incoming calls give busy signal

[Maxwell Paine]

Hi folks, 

I've been racking my brain for hours over this and finally after hours of internet searching and reading technical manuals, I feel like I should turn to the community for help because I feel as though I am missing something super easy. I am trying to set up a lab CME on a 2821 router in my test lab and have gotten the system set up, a couple of extensions running and a SIP trunk registered with outbound calling working, but for the life of me cannot figure out how to get inbound calling from elsewhere working properly. All I get from dialing the number of the CME is a busy signal. 

Below is the #show run of the router. Below that is a debug of when an incoming call from my cell comes in. Sensitive information has been removed. Basically the way this is supposed to work is the cme number is dialed, it matches it, rings 1010 which is a parallel group which rings 1001 1002 1003 and 1004.
