I seem to recall one post that referred to a URL that discussed the ins and outs of phone wiring. Things like recommended distances between phone and electrical cables. I know in my house, there's a place where the telephone cable wraps several times around some electrical cables!
Sorry I can't be more help here, but do try some searches, both internet and here, and hopefully you'll find. And if you do, please post for us! (One of these days, I'll work on mine!)
