74 CHAPTER 1: INTRODUCTION The 3Com Convergence Client (supported in SIP mode only) and generic SIP telephones are all Group 1 devices. Dynamic License Assignment NBX Group Licensing is a dynamic system that assigns licenses in the most efficient manner. A Group License can activate devices belonging to that group or devices with fewer features. For example, a Group 2 license normally activates Group 2 devices but it may also activate Group 1 or Group 0 devices. If a device needs a license and no license is available for that group, the system "loans" a license from a higher license group if a license is available in that group. License loans are automatic. The system dynamically assigns available licenses to devices to achieve the most efficient use of the installed licenses. Dynamic allocation can cause a more valuable license to be used for a less valuable telephone. For example, using a Group 2 license for a Group 0 device might be desirable as an interim solution, but if you later add a Group 2 device, you would probably want to purchase a Group 0 license for the Group 0 telephone and use the Group 2 license for the Group 2 device. Figure 24 Licensing and Upgrades > Licenses > Usage Report The first column in the License Usage Report shows the number of device licenses currently in use. The second column shows the number of licenses in each License Group that have been installed on the system. These examples demonstrate the flexibility of NBX Group Licenses.
