Configuring the Avaya 1120E IP Deskphone
113
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.
Table 14 on page 113 lists the features of a third–party USB headset with
HID support.

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.
