Unable to create channel of type 'ZAP' (cause 0 - unknown)

I have just set up a new install of Asterisk@Home. I got softphones like X-lite working on it. I’m trying to dial to the outside via a T100P single span T-1 board. When I dial on X-lite I get a message that “All circuts are busy”.
Watching the file /var/log/asterisk/full lets me see this message.
“Unable to create channel of type ‘ZAP’ (cause 0 - unknown)”

I’m not sure where to go from here as far as troubleshooting the exact problem. Are there any ways to monitor or test the T-1 interface to see whats going on with it.

Here are some of my config files.
