Multicast Paging
You can use multicast paging to quickly and easily broadcast time-sensitive 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.
Note If G722 codec is used for multicast paging, the touch screen will display an “HD” icon to
indicate that the audio you are listening to is high definition voice quality. Check with your
system administrator to see if this feature is available on your phone.
