If remote users *only* need to call contacts *within the office*, then whatever 
other precautions you take, make sure they land in a context which does not 
allow outside calls.

If you're feeling sufficiently evil, use Audacity to create a file with a few 
seconds of ringing-out tone followed by a deathly silence; and play this to 
remote users calling numbers they shouldn't, before doing a Hangup().
