Asterisk: 1.8.15.0

We are running this in a school and the students have apparently figured out the paging codes. We have the Paging Pro module on the system as well. I am looking for a way to restrict what extension can or cannot dial the page numbers. I have thought about extension routing but these are internal calls. I have tried blacklisting and that doesn't seem to do the trick.
