You can specify up to 10multicast addresses that the phone listens to on the network.How the phone handles incoming multicast paging calls depends on Paging Barge and PagingPriority Active parameters configured via web user interface.Paging BargeThe Paging Barge parameter defines the priority of the voice call in progress. If the priority ofan incoming multicast paging call is lower than that of the active call, it will be ignoredautomatically. If Disabled is selected from the pull-down list of Paging Barge, the voice call inprogress will take precedence over all incoming multicast paging calls. Valid values in thePaging Barge field: 1 to 10: Define the priority of the active call, 1 is with the highest priority, while 10 is withthe lowest. Disabled: The voice call in progress will take precedence over all incoming paging calls.Paging Priority ActiveThe Paging Priority Active parameter decides how the phone handles incoming multicastpaging calls when there is already a multicast paging call on the phone. If enabled, the phonewill ignore incoming multicast paging calls with lower priorities, otherwise, the phone willanswer incoming multicast paging calls automatically and place the previous multicast pagingcall on hold. If disabled, the phone will automatically ignore all incoming multicast paging calls.
