Column	Description
Registration Status	The registration status of the device with the Call Server:
	• Active — The device is registered and can make and receive calls.
	• Inactive — The device’s registration has expired. Whether it can make and
	receive calls depends on the system’s rogue call policy (see Call Server Settings
	on page 234). It can register again.
	• Permanent — The device’s registration never expires.
	• Quarantined — The device is registered, but it can’t make or receive calls until
	you remove it from quarantine.
	• Quarantined (Inactive) — The device was quarantined, and its registration has
	expired. It can register again, returning to Quarantined status.
	• Blocked — The device is not permitted to register. Whether it can make and
	receive calls depends on the system’s rogue call policy. It remains blocked from
	registering until you unblock it.
	A device’s registration status can be determined by:
	• An action by the device.
	• An action applied to it manually on this page.
	• The expiration of a timer.
	• The application of a registration policy and admission policy (see Registration
	Policy on page 264).
