Mobile Connect uses licensing. Checking the Enable Mobility check box in the End User Configuration window triggers licensing to consume device license units (DLUs) for Mobile Connect; the number of licenses that get consumed depend on whether you assign an adjunct device to the end user specifically for Cisco Unified Mobility. For specific information on how licensing works with Cisco Unified Mobility, see the following sections:

Checking the Enable Mobility check box in the End User Configuration window triggers licensing to consume device license units for Mobile Connect. The number of device license units that are consumed depends on whether you assign the end user an adjunct device, that is, a desktop phone, for example, specifically for Cisco Unified Mobility. You assign the end user an adjunct device for Cisco Unified Mobility by choosing a device from the Primary User Device drop-down list box in the Mobility Information pane in the End User Configuration window, not by clicking the Device Association button in the same window.

•If you enable Mobile Connect and fail to assign the end user an adjunct device for Cisco Unified Mobility, four DLUs get consumed, as indicated in the Mobility Enabled End Users row in the License Unit Calculator window.

•If you enable Mobile Connect and assign the end user an adjunct device for Cisco Unified Mobility, two DLUs get consumed, as indicated in the Mobility Enabled End Users (Adjunct) row in the License Unit Calculator window.
