So I got all the phones, except one, working again.
I think that one was the problem.
But I'm trying to figure out what is wrong with that one phone line.
What's happening, is that if I connect it, and call the house, it will ring one time and ring continuously.
Nothing happens on the caller side. Ring one time, and nothing.
I tested the phone by plugging it into a working plug.
I replaced the line from the main box to the wall plug. About five feet long.
Narrowed it down to the wall plug box. i think.
It's a new box. Old one had corrosion on the terminals.
Question...........
Old box had six wire connectors, on the female plug side.
New one had only four.
Could this make a difference???
