1. Perhaps I used incorrect terminology with polarity guarded. These are old-style 2500 TT telephones that require correct tip and ring to dial out on.
2. My provider is good ole AT&T Indiana.
3. I did not install a polarity guard so I am sorry if I gave anyone that impression. But it is not a matter of competence with me - it is a matter of time and dealing with wiring that has no "give." It comes out of the wall a fixed length - no slack. That is the way the electrician pulled the wire.
4. I saw the installer physically change the two wires in the NID. Today I went out and confirmed he was working on line 1 as we have 2 lines coming into the NID.
5. Yes, I could dial out on a rotary phone or phone without polarity issues.
