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 the priority of an incoming multicast paging call is lower
than that of the active call, it will be ignored automatically. 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.
