Class of Service

• Description
Class of Service (COS) sets various features and Dialling options (called items) for
extensions. The system allows any number of extensions to share the same Class of
Service. An extension can have a different Class of Service for each of the Night
Service modes. This lets you program a different set of Dialling options for daytime
operation, night time operation and even during lunch breaks. An extension's Class of
Service can be changed in system programming or via a Service Code (normally 777).
