2.3.8 Configure the Multicast Parameters
The Multicast Configuration page allows the device to join up to ten paging zones for receiving
ulaw/alaw encoded RTP audio streams.
A paging zone can consist of one or many CyberData multicast group-enabled products. There is no
limit to how many speakers can be in a given paging zone. Each multicast group is defined by a
multicast address and port number.
Each multicast group is assigned a priority, allowing simultaneously arriving pages to be serviced
based on importance. Multicast groups are compatible with IGMP through version 3. The device
supports simultaneous SIP and Multicast.
