As someone who works in the telecom industry and has to deal with faxes in medical facilities all the time, no they're not. I fucking wish they were.
I beg people to use e-fax solutions if they insist on using fax at all, but there are so many damn human macros out there who learned how to do something one way and totally break down if you try to make them do something different.
Annoyingly while most modern fax machines are also network printers and support email in both directions, the majority do not provide any way to configure a mapping so that a user can type in a number like a normal fax machine and the machine will convert it to the required email format for an e-fax service. This would be so easy and solve so many problems.
