I believe that European phones use the outer two wires of a four wire RJ cord, whereas North American phones use the inner two wires.

Adding voltage to the pins is usually only for instances where you need to power an external ringer, if I recall.

Here’s an old NTLK thread on NotePhone wiring ...
