Cisco TelePresence System Codec C20
Contents Introduction
Audio configuration
xConfiguration Audio Microphones Mute Enabled
Determine whether audio-mute is allowed or not. The default value is True.
Requires user role: ADMIN
Value space: <True/InCallOnly>
True: Muting of audio is always available.
InCallOnly: Muting of audio is only available when the device is in a call. When Idle it is not
possible to mute the microphone. This is useful when an external telephone service/audio system
is connected via the codec and is to be available when the codec is not in a call. When set to
InCallOnly this will prevent the audio-system from being muted by mistake.
Example: xConfiguration Audio Microphones Mute Enabled: True
xConfiguration Audio SoundsAndAlerts KeyTones Mode
The system can be configured to make a keyboard click sound effect (key tone) when pressing a
key on the remote control, or when typing text or numbers on the touch screen control panel.
Requires user role: USER
Value space: <Off/On>
Off: No key tones will be played when you type.
On: You will hear a key tone when you press a key or type text.
Example: xConfiguration Audio SoundsAndAlerts KeyTones Mode: Off

Sets the ring volume for an incoming call.
Requires user role: USER
Value space: <0..100>

Set the acoustic echo cancellation reference delay mode.
Requires user role: ADMIN
Value space: <Off/Fixed>
Off: No extra latency will be added to reference signal used by the acoustic echo canceller.
Fixed: The extra latency given by Audio EcReferenceDelay Delay will be used to compensate for
latency in the acoustic path, typically introduced by TV monitors.
Example: xConfiguration Audio EcReferenceDelay Mode: Off
Adjust the time slot (in milliseconds) of the acoustic echo cancellation. Only applicable when Audio
EcReferenceDelay Mode is set to Fixed.
