Well guys, now I don't feel like a complete loser! I have stopped trying.

I don't know what company did the install since it was in 2001. after that outside pedistool there is 1 long punch down block in each building, with another one of those small blocks that has the yellow/black "towers" on them. A few years ago to get one of the stations working again for our Camp Nurse's station, I had to take that block out of that picture.

Our phone guy here thinks there is a major short somewhere and/or the installer miss-wired a pair, which would make sense, with all the info you guys have given me here.
