Setup to Enable or Disable CNF for a Cisco Unified CM Cluster
-------------------------------------------------------------

The following steps are a checklist to enable change
notification for a Cisco Unified CM cluster in VOSS-4-UC.


1. Ensure the Service is enabled and configured in Cisco Unified CM. (:ref:`CUCM_setup_for_CNF` )
#. Enable Change Notification on the Cisco Unified CM cluster in VOSS-4-UC. (:ref:`detailed_VOSS-4-UC-CNF-functionality`)
#. Review the detailed Change Notification settings for the cluster. (:ref:`detailed_VOSS-4-UC-CNF-functionality`)
#. Review or create the required Data Sync instances for change notification
   for the cluster.  Refer to the topics on Data Sync following :ref:`data_sync`.
   
   The number of syncs and their setup will depend on the needs for your system and the design.

   See the Best Practices Guide for guidance on sync logic and recommended
   setups.  If further recommendations or guidance is needed, contact 
   your VOSS account team or VOSS support.
#. Review or create required schedules for the Data sync(s) created above
   and activate the schedule(s). (:ref:`enable_a_scheduled_data_sync`)
   
   Follow the guidance for scheduling around
   syncs to ensure the load on the system is optimized. At least one
   sync schedule should be activated for the CNF setup to be complete.

   
Follow the steps in reverse in order to disable change notification for
the cluster.
