• 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

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)

compression.
Auto Brightness detects and automatically adjusts the brightness of video
windows that are dimmer than other video windows in the conference

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
