1. Introduction
These Application Notes describe a compliance-tested solution comprised of Avaya IP
Softphone and the GN Netcom GN 8120 USB headset adapter. The GN 8120 USB headset
adapter provides physical in-line control of basic softphone call functions, such as off-hook/on-
hook, hold, and mute, and incorporates digital signal processing to enhance audio quality. For
integration with Avaya IP Softphone controls, a GN 8120 USB driver specific to Avaya IP
Softphone, provided by GN Netcom, must be installed on the Windows PC/laptop on which the
Avaya IP Softphone runs.
The GN 8120 connects to a USB port on one end and to any QD-equipped (Quick Disconnect)
GN Netcom headset on the other end. During the compliance testing, GN 2125 NC headsets
were used. The GN 8120 contains three call function buttons with associated call function LEDs
and a volume rocker for adjusting the audio volume heard on the headset. The mapping between
the three function buttons/LEDs and Avaya IP Softphone is generally as follows:
•
Green button – on-hook/off-hook, answer/hangup call.
•
Green button LED – indication of on-hook/off-hook, incoming call.
•
White button – put call on and take call off hold.
•
White button LED – indication of call on hold, voice message waiting.
•
Red button – mute on/off.
•
Red button LED – indication of mute on/off.
•
Blue button – volume rocker.
When two buttons on the GN 8120 are pressed simultaneously, the “Customer User Defined
Event” is invoked and causes the Avaya IP Softphone to dial a pre-defined number, i.e. voice
mail or 911. The number is defined during installation of the GN 8120 USB driver.
Figure 1
shows a sample configuration consisting of an Avaya S8300 Media Server residing in
an Avaya G350 Media Gateway, Avaya IP Softphones, Avaya 4600 Series IP Telephones, GN
Netcom GN 8120 USB headset adapters, and GN Netcom GN 2125 NC headsets. Note that the
solution described herein is also extensible to other Avaya Media Servers and Media Gateways.
The Avaya IP Softphones and Telephones register with Avaya Communication Manager running
on the Avaya S8300 Media Server.
