Multipoint Conferences
For SVC-based conferences, only SVC-enabled endpoints, such as the RealPresence Desktop
and RealPresence Mobile applications, can connect to a configured SVC Only conference on
the RealPresence Collaboration Server and the RealPresence Virtualization Manager
(DMA). Non-SVC endpoints are not able to connect to SVC Only conferences.
SVC-based conferences are established on the RealPresence Virtualization Manager (DMA)
through Virtual Meeting Rooms. Participants to SVC-based conferences can dial-in to the
Virtual Meeting Room using a SIP URI, SIP IP address, or a Meeting Room number.
Examples of these can be:
• SIP URI — 724999@polycom.com
• SIP IP Address — 1111@123.45.67.89
• Meeting Room — 724999
The RealPresence Collaboration Server 800s currently enables an SVC participant to directly
dial-in to a Meeting Room or an ongoing conference or dial-in through an Entry Queue.
VMRs can also be located in the Contacts list when the RealPresence Resource Manager is
connected with the enterprise LDAP. The RealPresence Resource Manager controls the
provisioning of the enterprise computers.
The RealPresence Virtualization Manager (DMA) is used for call control, SIP proxy, and
conference management. The RealPresence Virtualization Manager (DMA) allocates a
RealPresence Collaboration Server for sending and receiving video streams to and from the
SVC-enabled endpoints. When the RealPresence Collaboration Server is allocated, it detects
if all endpoints support SVC capabilities and allows SVC-enabled endpoints to connect.
When an endpoint in the conference is not an SVC endpoint, the RealPresence Collaboration
Server rejects the call and does not allow it to connect to the conference.
The RealPresence Collaboration Server provides the information on the SVC streams for
each endpoint in the conference and negotiates the required video streams to be sent to the
endpoints.
Using the RealPresence Desktop or RealPresence Mobile applications, the user is able to dial
to VMRs and other participants, view other participants in a continuous presence video
layout, control video and audio mute, and share content.
Video Layouts
Depending on the number of participants in the multipoint conferencing, video layouts are
automatically configured for displaying on the participant endpoint. The participant that is
currently speaking is displayed in the larger video pane and the participants currently
listening are displayed in the smaller video panes.
The following video layouts are used in an SVC-based conference using the RealPresence
Desktop or RealPresence Mobile clients.
