Subject: RE: Question about modems
What do you need to do to use an acoustic modem with a
cellphone?
You can get a "retro" handset for a cellphone, that will fit the rubber
cups, but, will it work?
I have one of those handsets, and somewhere in the basement, a Radio Shack
acoustic modem, so I could actually try it.
I expect it would work, but would suffer from a lot of line noise because of
how modern telephony works.
My network routes calls via UMTS, not VoLTE. I've never done a VoLTE call,
so perhaps it would be better.
