Configure Class of Service (provider deployment)
-------------------------------------------------

Use this procedure to create a new Calling Search Space (CSS) or edit an
existing CSS that is tied to a site. The CSS can be used as a Class of
Service (COS) for a device or line, or any of the other templates that
rely on COS to filter different features.


**Perform these steps**:

1. Log in as provider, reseller, or customer administrator.

   Warning:
   
   When adding Class of Service, ensure that you select a valid
   site under the customer in the hierarchy node breadcrumb at the top of
   the view. If you attempt to add a Class of Service at any other node
   in the hierarchy, you will receive an error indicating that you must
   be at a site.
2. Choose **Dial Plan Management > Site > Class of Service**.

   Note:
   
   There is one default Internal Calling Line Identification
   Presentation (CLIP) Class of Service that appears in the list. The
   default COS is provisioned automatically based on the criteria you
   selected when you added the site.

3. Perform one of:

   * To add a Class of Service, click **Add**.
   * To edit an existing class of service, click on the COS to be edited, edit the
     required fields and then click **Save**.
   * To clone an existing class of service, click on the COS to be cloned, and
     then click **Action > Clone**.

4. Enter a unique name for the Class of Service in the **Class of Service
   Name** field. Try to make the name as descriptive as possible using up
   to 50 alphanumeric characters, including spaces, period(s), hyphens
   (-), and underscore characters (_). You can also make use of macros
   that are available in the system to create a Class of Service name.
   For a list of possible macros, see "Macros and Site Defaults Macros" in the
   "Advanced Feature Guide". Macros allow you to dynamically add site IDs, customer
   IDs, and other types of information to the CSS.

   Example: Cu1-24HrsCLIP-PT-{{macro.HcsDpSiteName}}

   Note:

   The actual CSS that is sent to the Cisco Unified Communications
   Manager (based on the macros entered) is mirrored in the Actual
   Calling Search Space field. For example, the macro example above
   changes to Cu1-24HrsCLIP-PT-SiteABC.

5. Add a description for the Class of Service in the **Description** field if
   desired.
6. Choose route partition members to include in the Class of Service by
   performing the following:

   a. Click + to add route partitions.
   b. From the drop-down menu, select a route partition member.
   c. Repeat this step as required until you have selected all desired
      members for this Class of Service.

   Note: To remove a member from the Class of Service, click -.
   
7. Click **Save** to add the Class of Service that you defined.
   The new Class of Service appears in the table of Classes of Service
   and it can be edited or deleted as required.
