Feature Description
Key Events Both types of headsets have equivalent
mechanisms to generate the following
key events:
• On Hook
• Off Hook
• Mute
• Volume Up/Down
The headsets send the corresponding
HID commands to the IP Deskphone to
synchronize call processing operations.
When the IP Deskphone receives these
commands, the IP Deskphone maps
them to the corresponding key events
(except the Volume Up/Down keys) as if
the keys on the IP Deskphone are
pressed.
If the corresponding keys on the
IP Deskphone are used instead, the
IP Deskphone sends the HID
commands to the headsets to allow the
headsets to update their internal state
machine.
LEDs Both types of headsets have LEDs on
the base station for status indication.
These LEDs are controlled by the
headset base stations themselves
according to their internal state
machines. The IP Deskphone has no
direct control of these LEDs.
