announcements to users who are listening to a specific multicast group. You can
configure the paging list 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.
