2.4.9 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.
1. Click on the Multicast menu button to open the Multicast page. See Figure 2-22.
