Multicast Paging
You can use multicast paging to quickly and easily broadcast time sensitive announcements out
to people who are listening to a specific multicast group. You can configure a multicast paging
key or a paging list key on the phone, which allows you to send a Real Time Transport Protocol
(RTP) stream to the pre-configured multicast address(es) without involving SIP signaling. You
can configure the phone to receive an RTP stream from pre-configured multicast listening
address(es) without involving SIP signaling. You can specify up to 10 multicast listening
addresses.
