Configuring the Avaya 1120E IP Deskphone

Call Release You can release an incoming call or an
outgoing call by pressing either the
Release (Goodbye) key on the
IP Deskphone or the On Hook
equivalent key on the headset. After a
call is released, audio data stops
between the IP Deskphone and the
headset.
If you are using the Plantronic headset,
to release a call, press and hold the
answer/release toggle button for more
than two seconds.
Call Mute The mute key event is handled
independently on the headset. The
corresponding HID command is sent to
the IP Deskphone to synchronize
IP Deskphone status. Mute status
indication on the headset is also
independent. When muted, the headset
streams blank audio to the
IP Deskphone and the IP Deskphone
also mutes the audio to the far end
(double muted).
Volume Up/Down This class of headsets manages volume
changes locally whenever Volume Up/
Down keys are pressed. Pressing the
Volume Up/Down keys on the headset
has no effect on system volume. The
IP Deskphone ignores volume events
from the headsets to avoid double
volume changes. On the other hand,
volume changes on the IP Deskphone
change the system setting and indirectly
affects the volume level on the headset.
