Alright, I have a 500 processor with an 4 port analog line card in it, and my shortcode for the paging is *80, the shortcode is a Dial and it is using line ID 1 which is the line ID of the first port on that card, the line is set to loopstart as is the Bogen paging system...however when I do *80 on a phone I get an "unobtainable" message. I look at System Status and see an error for that line "channels unavailable - out of service" I've double checked my stuff, not sure where to go from here?
