Amazingly enough, this is actually not true. Many smaller doctors' offices still have a physical fax machine. I work on automation for certain processes in healthcare and a very large proportion of the faxes we receive come from physical fax machines. You can see artifacts on the fax itself and sometimes the cover letter will have a scribbled note.
Do they still have POTS lines? Telecom companies are shutting down old SS7 switches so eventually all faxes are ultimately being sent over the Internet and it will be entirely vestigial.
The offices I know of do. We have a PBX, and a "bare" POTS line for the fax.
