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.

licenses currently in use. The second
