Well it may not be such a good idea to have them test by directly accessing the line.

I was on site today checking a few other things and ran into this problem. One of the secondary alarm lines is busy when called from the outside, if you go on it at the demarc (with all other equipment removed) you can get dial tone and place calls. The caller ID on the cell I called indicates the correct # so it's not a stolen or miss ID pair. Does not attempt to ring then trip, it's just solid busy.

Called Verizon and they tell me it will be fixed by Tuesday, Told them thats not acceptable as this is a line the public uses to report a fire. I streched the truth a little, it's realy a roll over in the event the main number is busy.

They called me back at 6pm and said it will be dispatched first thing in the morning, they insist it is a cable problem. I would think a line that can dial out and is not noisy should not make it busy but they insist it's not a switch problem.

Guess we will see who is right in the morning
