Gain
control
You can apply one of the following four gain control options by
selecting the associated radio button:
■ Use conference configuration: the participant inherits the
conference's AGC setting.
■ Disable AGC: do not apply AGC to the audio from this
participant.
■ Enable AGC: apply AGC to the audio from this participant.
■ Apply fixed gain: enter a dB value by which to adjust the
participant's audio gain; a positive gain amplifies, and a
negative gain attenuates, the participant audio. 1dB is
approximately 60% change, 3dB is approximately 100%
change and 5dB is approximately 300% change. For
example, if the participant sounds twice as loud as
everyone else, apply -3dB gain.
The selected gain control option is
effective immediately, and persists
until the participant leaves or the
conference ends.
If you need to set AGC in advance,
you can do so on a per conference or
per participant basis. You can apply
AGC when inviting ad hoc
participants or when preconfiguring
endpoints.
The gain control setting on this page -
the active participant's audio page -
takes precedence over any other gain
control setting, whether that was
preconfigured on the endpoint, the
conference, or the template.

DTMF
This control determines whether the DTMF tones from this
participant are audible to the conference. You can select one of
the following:
■ <use conference configuration>: DTMF from the active
participant is either muted or audible to the conference,
depending on the conference configuration.
■ Disabled: DTMF from this participant is audible to the MCU
and is transmitted on to the other participants.
■ Enabled: DTMF from this participant is audible to the MCU
but is not transmitted on to other participants.
Prevents others from hearing this participant (like mic. mute).
Allows others to hear this participant (stop muting participant).
Prevents this participant from hearing the conference (like
speaker mute).
Note:The endpoint may not always detect DTMF tones from the
MCU after you mute the audio from the MCU.
Allows this participant to hear the conference (stop muting
conference).
Selecting a Custom Participant View
You can add a custom layout to the choice of layouts available for this participant. You can customize this view by
