I never had a Space Phone-equipped television, but I read everything about Zenith TVs (the originals, not today's "Zenith"-branded flat screens) I can get my hands on, so I know a little about the Space Phone system -- but not nearly as much as VK member Doug, drh4683 in Chicago. Space Phone was available for only a year or two, and was discontinued by the end of the 1980s. It never returned and, of course, is not offered on today's "Zenith" branded flat panel TVs, the guts of which are made by LG.

My cable companies cable boxes do the reverse of this. If you have their phone service, it puts the caller ID on the TV screen, and can show you previous calls.

So theoretically you could hook a Zenith Space Phone TV to the cable box and get caller ID and full speakerphone functionality...
Did Zenith ever make a TV with both Space Phone and Zoom?
