3. Click Confirm to accept the change.
Note
You can configure the phone to receive a Real Time Transport Protocol (RTP) stream from the
pre-configured multicast address(es) and channel(s) without involving SIP signaling. You can
specify up to 31 multicast addresses and channels that the phone listens to on the network.
Note
How the phone handles incoming multicast paging calls depends on Paging Barge and Paging
Priority Active parameters are configured via web user interface.
Paging Barge
The paging barge parameter defines the priority of the voice call in progress. If the priority of an
incoming multicast paging call is lower than that of the active call, it will be ignored
automatically. If Disabled is selected from the pull-down list of Paging Barge, the voice call in
progress will take precedence over all incoming multicast paging calls. Valid values in the
Paging Barge field:
 1 to 31: Define the priority of the active call, 1 with the highest priority, 31 with the lowest.
 Disabled: The voice call in progress will take precedence over all incoming paging calls.
Paging Priority Active
The paging priority active parameter decides how the phone handles incoming multicast paging
calls when there is already a multicast paging call on the phone. If enabled, the phone will
ignore incoming multicast paging calls with lower priorities, otherwise, the phone will answer
incoming multicast paging calls automatically and place the previous multicast paging call on
hold. If disabled, the phone will automatically ignore all incoming multicast paging calls.
To configure multicast listening addresses via web user interface:
1. Click on Directory->Multicast IP.
2. Select the desired value from the pull-down list of Paging Barge.
3. Select the desired value from the pull-down list of Paging Priority Active.
4. Enter the multicast IP address(es) and port number (e.g., 224.5.6.20:10008) which the phone
listens to for incoming RTP multicast in the Listening Address field.
Default codec for multicast paging is configurable via web user interface only.
RTP stream is listened in the speakerphone mode by default. If you want to listen the RTP stream
using the engaged audio device (earpiece, earphone or speakerphone), contact your system
administrator for more information.
Fixed volume to play RTP stream for specified paging group is configurable by your system
administrator.
