I'm having trouble getting this working I have an X100P card from Digium, but I can't seem to get it working properly. I am pretty sure I have this thing setup properly and have attempted to follow a dozen tutorials, but none of them seem to be quite the same as what I've got. I just want to get this thing where it will answer and make calls from just one box for now, but all these tutorials I see are way more complex. I try to make a call and I get "All circuits are busy now" I've done some research and it seems this can be caused by an infinite amount of things, can someone please help, I really don't even know where to start explaining where I'm lost at.
