Not e If G722 codec is used for multicast paging, the LCD screen will display the
indicate that it is providing high definition voice.
Default codec for multicast paging is configurable via web user interface only.
You can configure the phone to receive a Real Time Transport Protocol (RTP) stream from
the pre-configured multicast address(es) without involving SIP signaling. You can
specify up to 10 multicast addresses that the phone listens to on the network.
How the phone handles incoming multicast paging calls depends on Paging Barge and
Paging Priority Active parameters 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 t o 10: Define the priority of the active call, 1 with the highest priority, 10 with the

lowest.
Disabled: The voice call in progress will take precedence over all incoming paging

calls.
Paging Priority A ctive
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 A ctive.

the phone listens to for incoming RTP multicast in the L istening Address field.
5. Enter the label in the L abel field.
