Settings | Classes of service

Font	Action
1.	Station is used to assign stations for day and for night to the service groups 1 to 15.
2.	Individual COS groups are assigned classes of service from via Day or Night. The classes of service range from highly restricted to totally unrestricted access. Each group and route (trunk group) is allocated its own classes of service for day and night operation.
3.	Create lists of allowed and denied telephone numbers (Allowed/Denied numbers). These lists are referenced by the classes of service "Allowed list 1-6" and "Denied list 1-6".
4.	If toll restriction should not be activated (other than in the basic settings) for individual call numbers, this can be set up in the Dial plan. This also applies to networking.

The above mentioned steps can be completed in any order. You may prefer to compile your lists or define your groups before you assign your stations to groups. These functions are highly interactive. You should have an general plan before you begin.
