Making an SVC-Based Conference Call
This chapter describes how to place an SVC-based conference call using the RealPresence SVC-Based Conferencing solution. It describes the conference call from the end-user perspective in addition to describing the SVC-based conference established in the RealPresence Collaboration Server and the RealPresence Virtualization Manager (DMA). Additionally, the chapter describes the various features that can be used in an SVC-based conference.
Using the Polycom RealPresence Desktop and the Polycom RealPresence Mobile Applications
The Polycom RealPresence Desktop application is designed as an enhancement and replacement of the existing Polycom CMA Desktop and m100 applications. However, in this release, the RealPresence Desktop supports the Windows platform only.
The Polycom RealPresence Mobile application provides video conferencing for tablets and smartphones, extending video beyond conference rooms, enabling organizations to deliver video collaboration to more users in more environments. RealPresence Desktop and RealPresence Mobile are fully SVC-enabled applications.
Making a Conference Call
There are several types of conferences:
•"Multipoint Conferences”
Point-to-Point Calls
Point-to-point calls enable one participant to call another participant for video conferencing. Using the RealPresence Desktop or RealPresence Mobile, a point-to-point call can be made between two endpoints using the SIP protocol. Point-to-point calls can also be done between standard-based H.323 and SIP clients.
For point-to-point calls using the SIP protocol, an exchange is performed for video capabilities between the participants at the beginning of the call to determine the preferred call characteristics by both sides. When that is determined, point-to-point calls uses the SVC error resiliency capabilities but only one resolution is sent between the endpoints.
