Class of Service

Customer administrators and higher level administrators can create and maintain a Class of Service (CoS) that apply to subscribers. A CoS specifies the Unified CM and Calling Search Spaces (CSS) for a subscriber’s line, thereby indicating whether local, national and international numbers can be called.

An administrator can create a CoS at a customer level hierarchy. A Unified CM is specified. A drop-down list of those available at the customer level is shown.

Optional device and line CSSs can also be added - either selected from those existing on the Unified CM, or else added. Macros can also be used when adding new CSSs, for example: CSS-Gold-{{macro.SITENAME}}.

When a CoS is modified, the Unified CM cannot be modified. In order to refer to another Unified CM, either clone an existing CoS or else delete it and re-add it.
