Audio Broadcast FAQs






What is the capacity for Audio Broadcast?


3,000 attendees


Which service does Audio Broadcast support?


Event Center only


Does Audio Broadcast support a mixed mode or hybrid audio conference?


Yes. The meeting role determines the type of connections. Hosts, presenters, and panelists join the meeting by using PSTN only. Attendees join by using Audio Broadcast initially (until they are promoted to full speaking privileges).


Does Audio Broadcast support third-party audio bridges?




How do I use UDP transport for Audio Broadcast sessions?


UDP is only supported for non-SSL sites. The IP ports 7500 and 7501 must be opened for outbound communication using UDP on the corporate firewall. UDP is selected automatically if the ports are open.


Can you use Audio Broadcast over dial-up connections?


Audio Broadcast can be used over dial-up connections although this is not a recommended application. UCF-based PowerPoint sharing works satisfactorily as long as Video is not enabled and only one active microphone is in use. Application and desktop sharing with Audio Broadcast is not supported.
