Geography doesn’t stop a determined attacker...
Just because its a little more difficult, that doesn’t mean it is
secure... If that were the case then Classified US Government Faxes wouldn’t
require crypto gear in line (see STU-III for an example of this that’s over 20
years old)

What security reasons? Its just
as easy to tap a PSTN line as it is to sniff a network connection,
the only difference is you might need a little bit different
hardware...
If it were about security, fax machines would
actually encrypt a fax but they don’t...

Real estator/law

I am always worried about sending my
