Somebody did that back in the 1980s. They put a small printer into a phone that had the same form factor as a Western Electric model 500.[1] This connected to a PBX and printed "While you were out" slips. It was a real product, but did not catch on. Anyone remember that thing? I saw ads, but never one in person.

I have a rotary phone, a voip adapter, and have been writing a local SIP server for another experiment. I am insanely tempted to replicate this.

Why not, as a fun thing?

The problem with a production product is refilling all those little rolls of printer paper. They will always run out when no one is available to answer the phone, of course.

Which rotary? Classic AT&T?
