Explanation:
You are least likely to be able to control the remote volume during a call from a Cisco TelePresence SX20
Quick Set endpoint. Only the local volume can be controlled on an SX20.
You can change the local or remote layout during a call from a Cisco SX20. The following video layout options
are available:
Auto
Equal
Overlay
Prominent
Single
The Auto layout option uses the default layout family. The Equal layout option displays all participants in
pictures of the same size as long as there is enough space on the screen to display them. The Overlay layout
option displays the active speaker or presentation in a full screen and displays the other participants in small
pictures-in-picture (PiP). The Prominent layout option displays the active speaker or presentation in a large
picture and displays the other participants in small pictures. The Single layout option displays only the active
speaker or presentation; the other participants are not displayed.
You can control the local or remote camera during a call from a Cisco SX20. However, you will be unable to
control the remote camera if the Conference FarEndControl Mode setting on the remote system is set to Off or
if the remote camera does not have pan-tilt-zoom (PTZ) functionality.
