I went to buy some single pair 22 ga cable to hook up a phone

and the "expert" who had apparently worked for the phone company as
well as holding an electrician's licence, told me I needed cat5, or
at minimum cat3 cable - 4 twisted pair. I told him he was wrong -
all of the exixting phones were connected with single pair and had
been working for years.
He argued with me so I went elsewhere to buy my wire.

People confuse what is often used, generally used, even recommended,
with what is necesary. They don't know how the stuff works; it
doesn't dawn on them that they have a phone at home with only four
wires, and they're doing good to remember what someone uses, no matter
who.

Actually, you need only two wires to make a 'phone go.
