Description
Each extension must belong to a Class of Service (COS). By assigning certain extensions to a COS, it is
possible to control the behavior and privileges of extension users (allowing or denying certain extensions
access to various features, extensions, and CO lines) depending on the duties appointed to them.
Many extensions can belong to the same COS by assigning each extension the same COS number, allowing
the same restrictions and privileges to apply to a group of extensions.
The following features are controlled on a COS basis:
a. ® 9.1.14 Internal Call Block
b. ® 6.1.6 FWD (Call Forwarding)
c. ® 4.1.9 DND (Do Not Disturb)—DND Override
