asterisk users - Jan 2007 - disable external-outgoing calls per extension

Hi all,
Is there a simple way to disable external outgoing calls on the basis of
calling extension ?

In other words I would like to have two different "groups" of internal
extensions, one enabled to place calls on the external PSTN,
the other only enabled to place internal calls or receiving external calls.

We "take" the external line using leading zero in dialed numbers.

We are using FreePBX to manage Asterisk.

Thanks in advance,

Andrea
