WebEx Event Center Release Notes and FAQs
Audio Broadcast playback muting is not available
when using a third-party bridge.
Hardware requirements
No special hardware is required to use the Audio
Broadcast service. A sound card and speakers or
headphones are all that is required.
Number of attendees
Audio Broadcast supports up to 3,000 attendees
per meeting.
Auto Start
If an Event Center meeting is scheduled with
Audio Broadcast, the streaming client starts
automatically when an attendee joins the meeting.
If the host has not joined the meeting, the
attendees will receive a recorded announcement to
inform them that the host has not yet joined the
meeting.
Hybrid PSTN/Audio Broadcast operation
Hosts, presenters and panelists in an EC meeting
join a PSTN audio conference. This conference is
automatically bridged to the audio streaming
servers that support the Audio Broadcast service.
Attendee phone privileges
Attendees may request access to the phone at any
time by pressing the phone icon under the
participant list. The host can grant or deny phone
privileges individually or in groups.
TCP/UDP support
Audio Broadcast can use UDP or TCP as a
transport method. UDP transport allows offers
lower latency for Audio Broadcast sessions. TCP
offers optional SSL security with slightly higher
latency. When VoIP is started as a service, each
client attempts to connect via UDP first, and then
reverts to TCP as a transport protocol. Meetings
can support a mix of UDP and TCP attendees.
SSL Support
Audio Broadcast can (if the site is SSL enabled)
use SSL as a transport method. SSL provides
highly secure transport for VoIP traffic. SSL may
introduce additional latency for Audio Broadcast
connections.
