/mcpDevice Only If a device is added to Cisco Unified Communications Manager and does not have an entry for OwnerUserID field in its Device Configuration window, then the device is not assigned or not associated to a user and called "Device Only". The licensing for "Device Only" devices is listed in the Cisco Unified Communications Manager Licensing - User and Device Support table. If a device is added to Cisco Unified Communications Manager and does not have an entry for OwnerUserID, then the device would require the minimum license type determined by device type, as shown in the Licensing - User and Device Support table. User and Device Once a device is assigned or associated with a user, by entering a user ID in the OwnerUserID field of the device, the licensing requirements for that user and device are determined by the type of device and the number of devices assigned to the user. For a user that owns one device, if the user ID of that user is added as OwnerUserID to one Essential device (such as a 3905, 6901, or analog device), then the User and Device minimum license that is required is an Essential license. This means that the one Essential license supports both the user and the device. If instead, that user ID of that user is added as OwnerUserID to one Basic device (such as 6911 or 6921), then the user and device minimum license that is required is one Basic icense. If the user ID of a user is added as OwnerUserID to one Enhanced device, the user and device minimum license that is required is an Enhanced license. For users that own more than one device, the minimum licensing is determined by the number of devices that are owned by the user. Cisco Unified Communications Manager Licensing table shows the maximum number of devices per user license that is supported. A user that owns two devices requires an Enhanced Plus license at a minimum. A user that owns more than two devices requires a CUWL license at a minimum. Cisco Unified Communications Manager Licensing - User and Device Support table summarizes Cisco Unified Communications Manager Licensing for User Only, Device Only, and User and Device.
