Mute in-band
DTMF
Use this option to mute in-band DTMF from
this endpoint. Choose from:
■ use conference configuration: the
setting for Mute in-band DTMF will
be determined by the configuration of
the conference
■ Never: the in-band DTMF from this
endpoint will never be muted. Any
DTMF tones sent from this endpoint
will be audible to conference
participants
■ Always: the in-band DTMF from this
endpoint will always be muted. Any
DTMF tones sent from this endpoint
will not be audible to conference
participants
■ When used for MCU control: if a
participant is using in-band DTMF to
control conference layout and for
other in-conference features, the
tones will be muted and will not be
audible to conference participants.
The MCU will only expect a participant
to use DTMF for MCU control if Layout
control via FECC / DTMF or Send
camera control to participants is set
to DTMF only, FECC and DTMF, or
FECC with DTMF fallback and FECC
has not been established, or if the
participant is able to use the in call
menu.
In some scenarios, where a conference is
cascaded onto an audio bridge, it might be useful
for one of the participants in that conference to be
able to send in-band DTMF to the MCU. This is for
the purposes of sending the conference ID or PIN
to the audio conferencing bridge. In this case, the
Mute in-band DTMF setting for the endpoint of
that participant needs to be Never. However, you
can instead send DTMF tones to the audio
conferencing bridge directly from the MCU; for
more information refer to Sending DTMF to an
audio bridge.
Unless you need to configure a particular setting
for this endpoint, set this to use conference
configuration and ensure you have the Mute in-
band DTMF setting as required in the conference
configuration (see Adding and updating
conferences).
This setting takes precedence over the per-
conference Mute in-band DTMF setting for
conferences into which the endpoint is invited.
Appear as a
recording
device
When this setting is enabled, the red
recording indicator dot is visible to other
conference participants.
This participant is labeled as a recorder on the
conference participants page.
Video to use
by default
Allows you to replace this participant's video
with that of another participant. Select <self>
(default value) to display this participant's
own video by default.
If you select another preconfigured endpoint
from the dropdown, the MCU will no longer
use this participant's own video by default:
instead, it will use the video stream from the
selected endpoint in most circumstances, for
example when this participant becomes the
active speaker.
If the selected Video to use by default is not
available, the MCU will use this participant's own
video if possible.
If the selected Video to use by default is
available, you can still show this participant's own
video if you need to by explicitly choosing it in
specific layout pane selections.
Dial out as Determines whether this participant is a chair
or a guest when in automatic lecture mode.
