2. Select the desired codec from the pull-down list of Multicast Codec.
The default codec is G722.
3. Click Confirm to accept the change.
Note If G722 codec is used for multicast paging, the LCD screen will display the icon
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 to 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
