Setting the Maximum CP Resolution for Conferencing
The MAX_CP_RESOLUTION flag value is applied to the system during First-time Power-up and after a
system upgrade. The default value is HD1080.
All subsequent changes to the Maximum CP Resolution of the system are made by selections in the Max
CP Resolution pane of the Resolution Configuration dialog box.
The Maximum CP Resolution of the Collaboration Server can be set to one of the following resolutions:
● HD 1080p60
● HD 1080p30
● HD 720p30
● SD 30
● CIF 30
Minimum Frame Rate Threshold for SD Resolution
The MINIMUM_FRAME_RATE_THRESHOLD_FOR_SD System Flag can be added and set to prevent low
quality, low frame rate video from being sent to endpoints by ensuring that an SD channel is not opened at
frame rates below the specified value. For more information see Modifying System Flags.
