Multicast Paging - Matrix Sparsh VP110 User Manual

Multicast Paging

Multicast paging allows IP phones to send/receive Real-time Transport Protocol (RTP) streams to/from the pre-
configured multicast address (es) without involving SIP signaling. Up to 10 listening multicast addresses can be
specified on the IP phone.
Sending RTP Stream
Users can send an RTP stream without involving SIP signaling by pressing a configured multicast paging key. A
multicast address (IP: Port) should be assigned to the multicast paging key, which is defined to transmit RTP
stream to a group of designated IP phones. When the IP phone sends the RTP stream to a pre-configured
multicast address, each IP phone pre-configured to listen to the multicast address can receive the RTP stream.
When the originator stops sending the RTP stream, the subscribers stop receiving it.
Procedure
Configuration changes can be performed using the configuration files or locally.
