Using Chair Control for Multipoint Calls
During some multipoint calls, you can use chair control to manage the video.
In this type of call, the chair controller can choose the site whose video is sent
to other sites in the conference. The chair controller can also disconnect a site
or end the conference. Any participant can choose to view a specific site,
request to be the broadcaster, or request to be chair controller.
Only one site at a time can be the chair controller. Before a site can become the
controller, the site with control must give up control.
The type of host for the multipoint call and the systems in the call determine
whether chair control is available.
To use the chair control options when you are in a multipoint call:
1. On a computer, open Internet Explorer 6.x or later.
2. In the browser address line, enter the system’s IP address, for example,
http://10.11.12.13
, to go to the video conferencing system’s web
interface.
3. Click Place a Call.
