I still have a USB Fax modem left over from when OS X supported such things. I'd like to be able to use my Mac to dial numbers--not to talk through the Mac, just select a number in my Contacts or on a website, dial it, and use the phone (FiOS landline) to talk. Is there any way to do this? All the old OS X phone apps seem to be dead. I've seen a tone generator app where you're supposed to hold up the handset so it can hear the tones coming from the Mac's speaker but it works poorly--I'm guessing even modest ambient noise defeats it--so I'd like something that uses the USB modem instead.
I'm still using Mojave but I suppose I'll update at some point, so forward compatibility would be great.
