Paging Key (Sends the RTP Stream)
You can configure a Paging key on the phone that allows you to send a Real Time Transport
Protocol (RTP) stream to pre-configured multicast address(es) without involving SIP signaling.
You enter a multicast IP address(es) and a port number for the Paging key, that when pressed,
initiates an outgoing multicast RTP session. This is called Group Paging on the IP phones.
You can also specify group paging RTP addresses that the phone listens for when receiving RTP
streams. You can specify up to 5 listening multicast addresses at the path,
Basic Settings->Preferences->Group Paging RTP Settings.
For more information about Group Paging and how it works, and to specify multicast addresses,
see
“Group RTP Paging (receives RTP streams)” on page 250 .
