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 signalling. 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 

on 

Click on Operation > Programmable Keys.

Select from Key 1 through Key 3.

In the Type field, select Paging.

In the Value field, enter a multicast IP address and a port number for the Paging key. When you press this key, the 
phone initiates an outgoing multicast RTP session to the specified address using the specified port (e.g. 
239.0.1.15:10000).

Note: 
The Value field allows for one multicast address entry only.

To receive RTP steams for Group Paging, you must also configure the Paging Listen Addresses parameter at the path, 
Basic Settings > Preferences > Group Paging RTP Settings. For more information about setting this parameter, see 

.

Click Save Settings.
