The box pictured is the Clipper-based successor to the AT&T 3600
secure phone.  They have a "bump in the cord" architecture; in the
case of the 3600, it plugged between the handset and the phone.  This
is a pain in the ass (there are six or seven "handset modules" that
plug into the unit, and you have to use one to match your phone -- or
get several and pray that one will match each phone you ever want
to use.)

We played with one of the 3600's at a Bay Area cypherpunks meeting
a few months ago.

I'd refer to the "Surity" as the "surly telephone device".
