Receiving RTP Stream
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. Up to 31
multicast addresses and channels that the phone listens to on the network can be configured.
Note
How the phone handles incoming multicast paging calls depends on Paging Barge, Ignore DND
and Paging Priority Active configured via web user interface.
Paging Barge
Paging Barge feature defines the lowest priority of the multicast listening address from which
the phone can receive an RTP stream when there is a voice call (a normal phone call rather than
a multicast paging call) in progress. If it is disabled, all incoming multicast paging calls will be
automatically ignored. If it is set to a specify priority value, the incoming multicast paging calls
with higher or equal priority are automatically answered and the ones with lower priority are
ignored. Valid values for Paging Barge:
1 to 31: Define the lowest priority of the multicast listening address from which the phone
can receive an RTP stream, 1 with the highest priority, 31 with the lowest.
Disabled: The voice call in progress will take precedence over all incoming paging calls.
RTP stream is listened in the hands-free (speakerphone) mode by default. If you want to listen the
RTP stream using other engaged audio devices (speakerphone, handset or headset), contact your
system administrator for more information.
Fixed volume to play RTP stream for specified paging group is configurable by your system
