My hardware engineering job got a lot of daily faxes. Folks from machine shops put documents/drawings in their big printer scanner, type our fax number, and the .pdf appears available to everyone in a network folder. Honestly it's cleaner than dealing with email and attachments. Less steps involved. They are high quality pdfs, so I wouldn't be surprised if it skips the phone call tech entirely somehow.

Don't laugh. Faxes are still heavily used in many industries, like construction.

It’s falling off quickly in construction, but health care is definitely huge for fax still

Pretty much any time you need to send medical records between doctors in different areas, or deal with a workplace injury or insurance authorization stuff, it's going to involve collecting fax numbers so they can fax documents between the offices.

The alternative is regular mail.

Fax? Not hand written letter on parchment, by courier on horse?

Parchment? How modern, used to be that you could simply send someone to shout your message at them.

Thats what twitter bots are for.

You had WORDS? How decadent.

No, we are more modern these days, I shall send a sternly worded telegram!
