•Site (endpoint) names, skins, message overlay etc. are not supported in Video Switching.

•Video forcing is enabled at the conference and participant levels.

•To connect to a Video Switching conference via Entry Queue, the Profile assigned to the Entry Queue must be set to Video Switching. It is recommended to use the same profile for both the destination conference and Entry Queue.

•The HD_THRESHOLD_BITRATE flag must be set in the System Configuration. The value of this flag is the system minimum threshold bit rate for HD resolutions. The line rate selected in the conference Profile must be the same as or higher than that specified by the HD_THRESHOLD_BITRATE flag.

The HD_THRESHOLD_BIT RATE flag is responsible for negotiation only, It does not guarantee that the endpoint will open an HD channel or transmit on an opened HD channel.

The HD_THRESHOLD_BITRATE flag line rate value ranges from 384kbps to 4Mbs, default is 768kbps. For more information, see "Modifying System Flags” on page 22-1.
