What is the purpose of suspending a cluster or sensor?
To refresh the total known phone count, removing phones that are no longer active because: •A cluster was set up for a pilot that has concluded—Suspending the cluster reduces the total known phone count, so that phones from another cluster can be monitored. •Phones were replaced—If the license limit has been reached, suspending and then resuming monitoring of the Cisco Unified CallManager to which the phone was registered allows new (replacement) phones to be accepted. •Sensors were relocated to a different switch or geographical location— If the license limit has been reached, suspending and then resuming monitoring of the sensor allows new phones seen by that sensor to be monitored by Service Monitor.
