Each time you set up a telephone, use the Station screen to assign a Class of Restriction (COR). You can create different CORs for different groups of users.

For example, you might want executives in your company to have different calling privileges than offered to receptionists.

When you set up a COR, you specify a Facility Restriction Level (FRL) on the Class of Restriction screen. The FRL determines the calling privileges of a user. The levels of FRL are ranked from 0 to 7 where 7 has the highest level of privileges.

On the Route Pattern screen, you can assign an FRL to each route pattern preference. The system checks the COR when the user makes a call. The system facilitates the call if the FRL of the caller is higher than or equal to the FRL of the route pattern.
