Setting video switching
The Media Application Server (MAS) video switching mechanism tracks the
active speaker for a video conference, and employs a specified amount
of video switching hysteresis. That is, a video-enabled speaker must be
deemed to be the active speaker for a specified amount of time before
actually gaining the video focus.
The value for the video switching hysteresis for a conference server can
be set through the Video Switching Hysteresis (ms) parameter
in milliseconds (ms).

A default value is provided. Take care when setting custom
values for Video Switching Hysteresis (ms), as
incorrect settings can create an unpleasant user experience.
For example, too small a value can lead to the video switching
too often, as the video switching becomes more sensitive to
background noise; likewise, too large a value can lead to a
noticeable lag in switching to a new active speaker's video.
