Disabling or enabling automatic gain control
About this task
Use the following procedure to turn Automatic Gain Control (AGC) for the handset, headset, or to
put the speaker to On or Off. The user can potentially override the AGC local procedure settings.
For more information, see Using Avaya 9608, 9608G, and 9611G IP Deskphone H.323 and Using
Avaya 9621G/9641G/9641GS IP Deskphones H.323 guides. If the values are changed, the
backup file stores the AGC values set by the user and does not save any setting established using
this local procedure.
When updating local Craft procedures or Admin menu procedures from a touch screen
deskphone, touching the line you want to change or the applicable softkey produces the same
result as selecting a line and pressing the applicable softkey on a non-touch screen IP deskphone.
