Description
When set to NO (default), the RMX sends
wide screen resolution to dial-out SIP
endpoints. Endpoint types that do not support
wide screen resolutions are automatically
identified by the RMX according to their
product type and version and will not receive
the wide resolution even if the flag is set to
YES.
When manually added and set to YES, the
RMX does not send wide screen.
Default: NO.
Set this flag to YES to enable the AGC option.
(Default setting is NO.) When disabled,
selecting the AGC option in the Participant
Properties has not effect on the participant
audio. For more information see "Adding a
Participant to the Address Book" on page 6-3.
The Auto Gain Control mechanism regulates
noise and audio volume by keeping the
received audio signals of all participants
balanced.
Note:
Enabling AGC may result in amplification of
background noise.

language translations of the video conference.

are disabled.
When set to YES, Closed Captions are
enabled.
When set to YES, it enables the use of an
identical prefix for different RMXs when
registering with a Cisco MCM Gatekeeper.
