Chair Control
General Information
Chair Control is a feature that allows any ViewStation EX in a
multipoint call to do the following:
❑ Select which sites to view
❑ Select which site broadcasts its video to all other sites
❑ Disconnect sites from a multipoint call
Any site in the call can access the Chair Control screen. However,
only one site can have chair control at a time. That site must release
the chair control before another site can acquire it.
Chair Control is not supported in mixed protocol conferences. For
more information, refer to Mixed Protocol Dialing
on page 192.
Note
This feature is optional. In order to enable this feature and all
multipoint-related capabilities, you must upgrade your system to
support multipoint calls. For more information, refer to Upgrading
the System for Multipoint Calls.
