If no CP resources are
available, the system
will automatically switch
to the video switching
conference.
When the system has no available multi-screen
conference resources, a user can still hold a video
switching conference. The maximum number of video
switching conferences can be held is equal to the number
of audio and video connection resources available in the
current system. When you select this option and use this
profile to create a multi-screen conference, the system will
automatically switch to the video switching conference if
no resources are available.
Only video stream 1 is
enabled.
When this option is selected, the conference will only use
the parameters for the first video stream channel. You
cannot configure Detailed Configuration.

for RMX 500 Rev B and RMX 1000 Rev C, this
option can be displayed on the page only if CIF/SIF has
been selected in People Video Definition.
