In a hundred of ways, I think the most straightforward is making a table 
in some database with two columns, 'user' and 
'unpermitted_prefix',
then before the dial put an agi which sets a variable looked by a gotoif 
which makes the difference between Dial and 
Playback(you-are-not-important-enough-for-our-company-to-let-you-call-everywhere).

I don't know how it works with prefixes in usa, maybe you can simply 
chek for 00 at the begginging of the ${EXTEN} so no need for agi, anyway 
the db solution is quite simple and adds little overhead, giving you 
flexibility which can come in hand for future requests ...
