You're thinking about it wrong.

Devices can only dial #s that match the dialplan in their context.  Simply 
don't include any extensions that match it.

It is also painfully obvious that you haven't read much on Asterisk.  I 
suggest you start by reading the Asterisk Handbook draft, and follow up by 
poking around the wiki and the mailing list, which is searchable with google.

and include "site: lists.digium.com" in your google terms to search the list.
