A simple solution to pulse dialling phones is to use an old

I hope you're not suggesting acoustic coupling. Over the years, I've
owned various "tone dialer" boxes:

Mostly, I used them to couple into a 2way radio microphone to control
a repeater or to simulate DTMF paging. When I attempted to
acoustically couple any of these devices to the telephone mouthpiece
in order to dial a number, I would get misdials, erratic dialing, and
a general failure to cooperate. Just like the bad old days of
Anderson Jacobson acoustically coupled 300 baud modems, it didn't work
very well. I had one device that plugged into the phone line via an
RJ-11 jack, which did work reliably.

At one time I used handheld remotes to dial old phones, never had a problem with it.
