/mcpResource Group. If there exists some media resources of the requested type which do not belong to any Media Resource Groups, then these devices will belong to the Default List. If the requested type of device is not configured in any of the Media Resource Groups of the Media Resource Group List for which the alarm is generated or in the Default List, add the requested type of device to a Media Resource Group in the specified Media Resource Group List or add it to the Default List. To add a media resource to the Default List, remove the Media Device from all the Media Resource Groups. In general, when a new media device is initially added to Unified CM it will automatically be added to the Default List. This Default List can be used by any device or trunk. But when the media device is added to any particular Media Resource Group it will not be available to the Default List. It can only be used by devices and trunks that are configured with the Media Resource Group List that have that particular Media Resource Group. Note that a particular Media Resource Group can be added to multiple Media Resource Group Lists. If the requested device is properly configured in Cisco Unified CM Administration, check whether the device is registered to Unified CM. To do that go to the Media Resources menu of the requested type of device (such as Annunciator or Conference Bridge or Media Termination Point or Music On Hold Server or Transcoder) and click the Find button. All the devices of that type will display along with their status, device pool, and so on. Check the status field to see whether the device is registered with Unified CM. Note that the display on the status field is not a confirmation that the device is registered to Unified CM. It may happen in a Unified CM cluster that the Publisher can only write to the Unified CM database and suppose the Publisher goes down. Because the Subscriber may not be able to write to the database the devices may still display as registered in Unified CM Administration after they are actually unregistered. However, if the Publisher is down that should generate another alarm with higher priority than this alarm. If the device is not registered, click on the name of that particular device and check the type of the device. Device types including Cisco Conference Bridge Software, Cisco Media Termination Point Software, or that specify a server name that is the same name as a Unified CM node of the cluster indicate that the requested device is a software device and is part of the Cisco IP Voice Media Streaming application. Check to be sure that the IP Voice Media Streaming App service is enabled on that Unified CM node (Cisco Unified Serviceability > Tools > Service Activation) and if it is not enabled, activate the Cisco IP Voice Media Streaming App service. Devices should try to register. You can also check the status of the service to be sure it is showing as Started (Tools > Control Center > Feature Services). If the device type is a type other than Cisco Conference Bridge Software, Cisco Media Termination Point Software, or a server name that is the same name as a Unified CM node, that indicates that the device is an external media resource to Unified CM. Check the configuration (such as Conference Bridge type, MAC address, and conference bridge name in the case of a conference bridge; Media Termination Point name in the case of a Media Termination Point; Transcoder type, MAC address, and Transcoder name in the case of a Transcoder) of the device in Cisco Unified CM Administration and compare it with the configuration of the actual device. To check the configuration of the actual device you may need to refer to the user manual of the media device. The user manual should provide all the details such as connecting to the media device to check the configuration, commands needed to view and update the configuration, and so on. If configuration in Unified CM and on the actual devices are different, make the necessary changes so that the configurations match. If the configuration matches and the device is still not registered, restart the external media device or the service associated with the external media device. If the external media device continues to fail to register with Unified CM, check the network connectivity between Unified CM and the media device.
