fixin' people's phones is what I do for a livin'!

Many people don't realize that a corroded jack can cause static on the line or worse-even hold down your dialtone. You can have a corroded jack somewhere in the house that isn't even being used or worse yet-you don't even know it exists and it will cause you problems. Go to each jack and shine a flashlight in it. Looks for any green on the contacts. This is corrosion. The most likely culprit will be a jack that is on an outside wall. These jacks have a tendency to get more moisture/humidity and will corrode faster than the others.

If you can't find a corroded jack go to your NID (box outside house) and look at the wires going from the box into the house. If there is more than 1, disconnect all but 1. Then go into the house and plug a phone into each jack and listen for static. You will NOT get dialtone on some of the jacks because you have some wires disconnected outside. BUT the jacks that you DO have dialtone on, how do they sound? If they are nice and clear you have eliminated those jacks and the wiring to them. Next connect another line and now check some of the other jacks that didn't have dialtone before. Continue this process until you have isolated which line is causing the problem. You may find that the 1 wire that is causing the static is connected to jacks that aren't even being used, or possible the wire is not connected to any jacks but has been chewed on by rodents or is corroded somewhere. Anyways you may find you don't even need that wire hooked up.
If that's the case, problem solved!

Good luck,
Frank
