The HID support of third-party USB headsets performs differently from the 
Avaya Headset. The headsets are independent devices with an internal 
state machine to control LED operations and headset behavior.

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.
