Outbound Traffic

• Selective streaming of voice, video, text presentations and files– With N of active participants, up to N*M streams are

available from a source conference.– Passive participants can choose any streams.

• Analogy to many cameras at one site, they can choose any cameras or views. This feature can be called “virtual camera control”

– Multi (intelligent or adaptive) -QoS support: choose the one suitable for your devices and networks.

• various kind of devices.
