John, I would do that, but what would you do if theres no static that day? If it's not doing it, how do you isolate it? There are ways using a SideKick, and been thinking of getting one for the shop, just don't know how. There are some other types of equipment too. Maybe someone has a really easy answer that I have over-looked all these years.
BTW, PacHell/SBC operaters are trained to always say "its an inside wiring problem". Something that I love to rub in when it's not. Like when I got the call for a dead phone line, customer calls PacHell, they say "inside wiring", I get there and the drop is in the street.
What I'm looking for is way to show up, CHARGE FOR IT, and say one way or the other.
