The host can grant or denyphone privileges individually or in groups. TCP/UDP supportAudio Broadcast can use UDP or TCP as a transport method. UDPtransport allows offers lower latency for Audio Broadcast sessions.TCP offers optional SSL security with slightly higher latency. WhenVoIP is started as a service, each client attempts to connect via UDPfirst, and then reverts to TCP as a transport protocol. Meetings cansupport a mix of UDP and TCP attendees. SSL SupportAudio Broadcast can (if the site is SSL enabled) use SSL as atransport method. SSL provides highly secure transport for VoIPtraffic. SSL may introduce additional latency for Audio Broadcastconnections. Back to top Frequently Asked Questions Q. When would I use Audio Broadcast in preference to Integrated VoIP?A.
