Understanding Class of Restriction Policies

A class of restriction policy is a statement that specifies a type of call and whether it is allowed or denied. Class of restriction policies are added to class of restriction (COR) configurations. If a policy allows a type of call and the COR configuration that contains it is assigned to a station (or to a template that is assigned to a station), the user of the station’s phone is allowed to make that call type. If a policy for the station denies the call type, the user does not have permission to make the type of call. Call types that can be allowed or denied include interbranch, local, long-distance, international, and custom calls. All branch users can make intrabranch and emergency calls, which do not require COR policies.

Note: By default, all classes of calls except emergency and intrabranch are denied.

You cannot create a single policy to allow more than one type of call or a single policy to deny more than one type of call. Each discrete policy specifies a single action, that is, to allow or deny a single type of call. You add policies to COR configurations.

This requirement lends itself to ease of use. For example, you can create a policy to allow national calls and assign it to a COR configuration for administrators. You can assign the same policy to a COR configuration for managers. You might also assign to the manager’s COR configuration a policy that allows international calls, but not assign that policy to the administrator’s COR configuration.
