That’s the reason we have to still use fax machines right?
I know there are ways to do encryption like PGP on your message directly or I think email sent over TLS? But that isn’t the default right and that’s why I can’t send a picture of my license to the insurance company directly over email?
It’s kind of true. But so many places are replacing physical fax lines with VOIP or even just automatically sending the fax to email via a copier, it’s hardly more secure in my experience
A lot of VOIP is local. So a phone line carries the signal to the office building, and a modem converts it to be emailed or whatever. At least in secure places like in healthcare or finance. On the consumer side, VOIP that you get from say a cable company, also doesn’t travel over the internet. It travels on the same local lines to the cable company, but from there it takes a different route. True the middle might still be digital, but it’s not using internet infrastructure. That would be a waste because there’s no need to be able to send that signal to any given device on the internet. There are a lot fewer landline phone numbers than internet connected devices.
