Avaya NN43170-100 Manuel D’Utilisation

 lists the features of a third–party USB headset with 

HID support. 

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 Phone receives these 
commands, the IP Phone 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.
