The video call bandwidth if set to None, will not allow allocation of bandwidth for video between this region and other region.
The video bandwidth if specified (say 384 kbps) is the maximum bandwidth allowed for 1 video call (mix of audio and video bandwidth) between this region and specified region. The audio stream in the video uses g722 (80 kbps) or g728 (16kbps). The video stream may use the rest of the bandwidth.
——————–Region versus Location settings—————————-
Region setting defines per call bandwidth setting between two regions.
Location setting define total bandwidth available between two locations.
Location bandwidth >= Region bandwidth between two sites.
