> Hospitals still use fax because it is a much more punishable crime to tap phone lines which requires physical access

Punishable, sure, but that's CYA thinking. It's less secure, because there's no way to encrypt fax like you can encrypt email. Punishment doesn't help anyone except the CEOs, unless, of course, it was the CEO's information that got leaked.

Also, yes, phone calls are sent over the Internet just like emails. The big difference is, yes, that phone audio isn't encrypted.
