Explanation A device that has previously registered with Unified CM has unregistered. In cases of normal unregistration with reason code 'CallManagerReset', 'CallManagerRestart', or 'DeviceInitiatedReset', the severity of this alarm is lowered to INFORMATIONAL. A device can unregister for many reasons, both intentional such as manually resetting the device after a configuration change, and unintentional such as loss of network connectivity. Other causes for this alarm could include a phone being registered to a secondary node and then the primary node coming online, which causes the phone to rehome to the primary Unified CM node. Or, lack of a KeepAlive being returned from the Unified CM node to which this device was registered. Unregistration also occurs if Unified CM receives a duplicate registration request for this same device. Recommended Action Actions to take vary depending on the reason specified in this alarm for the device unregistration. If the reason is ConfigurationMismatch, go to the Device Configuration page in Cisco Unified CM Administration, make a change to the Description field for this device, click Save, then reset the device. In the case of a network connectivity problem or loss of KeepAlives, use network diagnostic tools and the Cisco Unified CM Reporting tool to fix any reported network or Unified CM system errors. In the case of a device rehoming to the primary Unified CM node, watch for a successful registration of the device on the primary node. In the case of a duplicate registration request, it may be a non-malicious occurrence due to timing of a device registering and unregistering; if duplicate registration requests continue or if the same device has different IP addresses, confirm the IP address on the physical device itself by checking the settings on the device (settings button). If unregistration of this device was expected, no action is required. Also, refer to the reason code descriptions for recommended actions.
