Table 14: Third-party USB headset with HID support features (Part 1 of 5) (Part 1 of 5)

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.
