Corrected entry: There is a scene late in the movie, when they send a fax to the White House - "it's on a different line" So why don't they just use the handset of the fax machine to make a normal voice call? If the machine had no handset (can't remember) just switch the jacks of the phone and fax...

Correction: The "future Postmaster General" doesn't just say that the faxes are on different lines, but on different encryptions. If the fax lines are encrypted, the code for deciphering it would lie in the fax machine itself. You can therefore not switch jacks. And the fax has no handset.
