• Dial-in is available as follows:
— AVC endpoints (participants) can only connect to an AVC conference. When
dialing into SVC Only conferences they will be disconnected and the calls fail.
— SVC endpoints support both AVC and SVC video protocols.
When dialing into SVC Only conferences, they connect as SVC endpoints.
When dialing into AVC Only conferences, they connect as AVC endpoints. They
cannot connect to an AVC conference using the SVC capabilities.
• SVC endpoints cannot connect to SVC Only conferences via Entry Queues.
• SVC endpoints cannot be moved between conferences.
• Content is supported in H.264 (AVC).
— Only the H.264 Cascade and SVC Optimized option is supported.
— LPR and DBA are not supported for SVC content sharing.
• Auto Layout is the default and only setting to display the video on the endpoint screen.
• Site names display is controlled from the SVC endpoints.
• When DMA is part of the solution, the DMA is used as the SIP proxy and the SVC
endpoint subscribes to DMA for call control. If a DMA is not part of the solution, the
SVC endpoint dial directly to the RMX 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 (CP and VSW) conferences.
SVC endpoints connected to AVC conferences using their AVC capabilities will be
reconnected to their AVC conferences.

not supported for SVC endpoints. These endpoints will have to manually
reconnect to their SVC conferences.
