Audio Clarity improves received audio from participants connected via
low audio bandwidth connections, by stretching the fidelity of the
narrowband telephone connection to improve call clarity. The
enhancement is applied to the following low bandwidth (4kHz) audio
algorithms:
• G.729a
• G.711
• Guidelines
Note:
This flag sets the initial value for Audio Clarity during First-time
Power-up. Thereafter the feature is controlled via the New Profile -
Audio Settings dialog box.
Possible Values: ON / OFF
Default: OFF
For more information see
Packet Loss Concealment (PLC) for Siren audio algorithms improves
received audio when packet loss occurs in the network.
The following audio algorithms are supported:
• Siren 7 (mono)
• Siren 14 (mono/stereo)
• Siren 22 (mono/stereo)
Possible Values: ON / OFF
Default: ON
Note: The speaker's endpoint must use a Siren algorithm for audio
compression.
Auto Brightness detects and automatically adjusts the brightness of
video windows that are dimmer than other video windows in the
conference layout. Auto Brightness only increases brightness and does
not darken video windows.
Note:
This flag sets the initial value for Auto Brightness during First-time
Power-up. Thereafter the feature is controlled via the New Profile -
Video Quality dialog box.
Possible Values: YES / NO
Default: NO
