If you use ClearCom FreeSpeak wireless intercom systems, you might have noticed something odd in the overview page.
According to ClearCom, when using link-local addressing (meaning 169.254.X.X network IP addresses), the telemetry from antennae and beltpacks is not updated correctly.
The current fix is to use a fixed IP NOT in the link local address space.
ClearCom says they are working on a fix for this issue.
