Also much-later #wallphones with a hook you hung the #handset up on. Not as common parlance as "hang up", but going "off-hook" meant something physical. My family still had one in 1982. Harvest Gold.

My favourite bit of phone tech that didn't belong properly in either the analog or digital universes was pushbutton phones that had a selector switch that let you configure them to emit #DTMF tones OR #pulse trains. I had one; phone company charged $2 extra per month for DTMF support.
