Make the following decisions regarding class of restriction:
Restriction. The setting determines whether users can make local and/or toll
calls (the factory setting is for inside calls only).
You can change the setting to unrestricted (the users can make local and toll
outside calls) or restricted (the user can make only local outside calls).
Allowed List Assignment When users are restricted from making local
and/or toll calls, you can assign up to eight Allowed Lists that allow restricted
users to call specific numbers (local or toll).
Disallowed List Assingnment When users are not restricted from making
calls, you can assign a Disallowed List that prevents them from dialing
specific numbers on the list.
