Also, if you need private point-to-point phone capability
(without ringer), two old-style phone sets and a 9V battery
suffice.  Just connect everything in series.

About 30 years ago, I did that with two very old rotary phones
and a 9V battery between the bedrooms of my two daughters.  They
decided knuckles knocking on the wall between the rooms would be
their signal to pick up the phone.  When either phone set (or
both) hung up, battery current was close enough to zero that the
battery would last a very long time.
