Cisco TelePresence SX20 Quick Set  Administrator Guide
Conference MicUnmuteOnDisconnect Mode
Define if the microphones shall be unmuted automatically when all calls are disconnected. 
In a meeting room or other shared resources this may be done to prepare the system for 
the next user.
Requires user role: ADMIN
Default value: On
Value space: Off/On
Off: If muted during a call, let the microphones remain muted after the call is 
disconnected.
On: Unmute the microphones after the call is disconnected.
Conference Multipoint Mode
Define how the video system handles multiparty video conferences (ad hoc conferences).
If registered to a Cisco TelePresence Video Communication Server (VCS), the video system 
can use its own built-in MultiSite feature. If registered to a Cisco Unified Communications 
Manager (CUCM) version 8.6.2 or newer, the video system can use either the CUCM 
conference bridge, or the video system's own built-in MultiSite feature. Which option to use, 
is set-up by CUCM.
The CUCM conference bridge allows you to set up conferences with many participants. The 
built-in MultiSite allows up to four participants (yourself included). 
The built-in MultiSite is optional and may not be available on all video systems.
Requires user role: ADMIN
Default value: Auto
Value space: Auto/CUCMMediaResourceGroupList/MultiSite/Off
Auto: The multipoint method is selected automatically; if no multipoint method is 
available, the Multipoint Mode will be set to Off.
CUCMMediaResourceGroupList: Multiparty conferences are hosted by the CUCM 
configured conference bridge. This setting is provisioned by CUCM in a CUCM 
environment, and should never be set manually by the user.
MultiSite: Multiparty conferences are set up using the built-in MultiSite feature. If 
MultiSite is selected when the MultiSite feature is not available, the Multipoint Mode will 
automatically be set to Off.
Off: Multiparty conferences are not allowed.
Conference MultiStream Mode
The video system supports multistream video for conferences.
Requires user role: ADMIN
Default value: Off
Value space: Off
Off: Multistream is disabled.
Conference IncomingMultisiteCall Mode
Select whether or not to allow incoming calls when already in a call/conference.
Requires user role: ADMIN
Default value: Allow
Value space: Allow/Deny
Allow: You will be notified when someone calls you while you are already in a call. 
You can accept the incoming call or not. The ongoing call may be put on hold while 
answering the incoming call; or you may merge the calls (requires support for multiparty 
video conferences).
Deny: An incoming call will be rejected if you are already in a call. You will not be notified 
about the incoming call. However, the call will appear as a missed call in the call history 
list.
Conference Presentation RelayQuality
This configuration applies to video systems that are using the built-in MultiSite feature 
(optional) to host a multipoint video conference. When a remote user shares a presentation, 
the video system will transcode the presentation and send it to the other participants in the 
multipoint conference. The RelayQuality setting specifies whether to give priority to high 
frame rate or to high resolution for the presentation source.
Requires user role: ADMIN
Default value: Sharpness
Value space: Motion/Sharpness
Motion: Gives the highest possible frame rate. Used when there is a need for higher 
frame rates, typically when there is a lot of motion in the picture.
Sharpness: Gives the highest possible resolution. Used when you want the highest 
quality of detailed images and graphics.
