If a (either numerically (1) or specifically selected) user of a group is busy, the configured group is considered to be busy. Configurable action: Signal busy or follow busy forwarding. Data protection and functional integrity: Fluxpunkt modules "do not phone home" and are not dependent on the function/accessibility of external license servers.
Group Busy switches an entire call group busy as soon as at least one group member is busy. Optionally, a specific user can be selected that determines the busy status of the group.
Investment protection: no dependence on external services/license servers
Cheap: Licensing once per server. No software maintenance or running costs!
