Ignore DND
Ignore DND feature defines the lowest priority of multicast listening address from which the
phone can receive an RTP stream when DND is activated. If a priority is selected from the
pull-down list of Ignore DND, the phone will ignore incoming multicast paging calls with lower
priorities when DND is activated in phone mode. Valid values for Ignore DND:
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: All the incoming multicast paging calls will be ignored when DND is activated in
phone mode.
The phone will automatically answer all incoming multicast paging calls when DND is activated
in custom mode.
Paging Priority Active
Paging Priority Active feature 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.
