●
When a RealPresence DMA system is part of the solution, the DMA is used as the SIP proxy and the
SVC endpoint subscribes to the RealPresence DMA system for call control. If a RealPresence DMA
system is not part of the solution, the SVC endpoint dial directly to the Collaboration Server using IP
addresses is the SIP dialing strings.
●
When Hot backup is enabled, all the conferences are created on the Slave MCU.
●
When Hot Backup is activated and the Slave MCU becomes the Master MCU:

All AVC endpoints will be reconnected to the AVC conferences. SVC endpoints connected to AVC
conferences using their AVC capabilities will be reconnected to their AVC conferences.
 SVC endpoints cannot be reconnected to their SVC Only conferences as dial-out is not supported
for SVC endpoints. These endpoints will have to manually reconnect to their SVC conferences.
●
Cascading between SVC Only conferences or between AVC and SVC Only conferences is not
supported.
●
The following functionality and features are not supported during SVC Only conferences:
 FECC
 Skins. The video cells are displayed on the endpoint’s default background.
 IVR functionality
 Conference Gathering phase
 Password protected conferences as DTMF input for passwords cannot be processed
 All DTMF enabled features during the conference
 Manual selection of video layout
 Chairperson functionality
 Media Encryption
 Recording of SVC Only conferences
 Text messaging using Message Overlay
MCU Supported Resolutions for SVC Conferencing
The MCU automatically selects the resolution and frame rate according to the conference line rate. The
table below details the maximum resolution and frame rates supported by the MCU for each conference line
rate. The actual video rate, resolution and frame rates displayed on each endpoints is determined by the
endpoint’s capabilities.
