Using authorization codes, a caller can override the calling privileges. For example, you can give a supervisor an authorization code so that they can make calls from a telephone that is usually restricted for these calls. Since each authorization code has a Class of Restriction (COR), the system uses the COR that is assigned to the authorization code, and the FRL assigned to the COR to override the privileges associated with the restricted phone.

Authorization codes do not override dialed strings that are denied. For example, if your Automatic Route Selection (ARS) tables restrict users from placing calls to destinations that are outside of the country, a caller cannot override the restriction with an authorization code.
