In multicast server mode a 16 channel Gateway codec supports sending 1, 2, 3, 4, 6, 8 or 16
multicast audio streams to unlimited endpoints over compatible IP networks. It is also possible to
use multicast client mode to simultaneously receive up to 16 separate multicast streams.

How Multicasting Works
Multicast transmissions are sent using a dedicated IP multicast address that looks similar to a
regular IP address and multicast subscribers request transmissions from this address. This unique
address allows multicast routers to identify multicast requests from a group of codecs interested in
a particular transmission and packets are replicated depending on demand. This can create large
demands on network bandwidth if the multicast group is significant in size.
As a result, only small sections of the internet are multicast enabled and many internet service
providers (ISPs) block multicast traffic over wide area networks. This restricts most multicast
broadcasts to private local area networks. Some ISPs provide quality of service (QoS) priority to
multicast streams for an increased service charge. You need to check with your ISP to find out what
multicast services, if any, are available over WANs.
