Well, I believe that everything you've mentioned is somewhere in the
scope of a "cell phone". Maybe barely, but close counts in this context.
For the phone that is probably in your pocket right now I've used one
of those bluetooth bridges that looks like a bluetooth handsfree device
to the phone but on your side you get a 48/90v POTS RJ11 for a regular
phone.
Interesting. I wasn't aware that such a permutation existed. Though it
seems somewhat obvious in hindsight.
You can attach a modem to them but some of those adapters do not emit
a dial tone.
No dial tone can probably be worked around via AT commands / firmware
settings to not wait for a dial tone.
I think ringing voltage might be more important for handling incoming calls.
These older adapters have major problems regarding audio quality and
noise cancellation. I could not relaibly make it hold a connection
above 300bps.
Ugh.
Even 110bps had spurious corruption from time to time so barely
enough for a teletype connection and over an acoustic coupler it was
not a lot better by using one of those hipster handsets that plugged
into the headphone jack on phones, when a headphone jack was still
a thing......That feels weird to even say.

The data kit and MSAT are the types of interaction that I was thinking
of when I started this thread.
The more that this thread, and others like it continues, I'm feeling
more and more like the retro X.25 network that people like æstrid and co
are making is something I need to look into more.
