Hi Randy,
Not that I know of.
In my previous experience with government agencies,
the primary concern about PSTN Fax was that it could be
used *from a compromised system or by a rogue walkup
user* to export documents and system configuration
information invisibly, i.e., w/out passing through a firewall
and w/out any chance of detection by smart routers
(ones with embedded firewalls).
Cheers,
- Ira
