paging calls with higher or equal priority are automatically answered and the ones with lower
priority are ignored.
Ignore DND
This parameter defines the lowest priority of the multicast paging call that can be received
when DND is activated in phone mode. If the value of the parameter is configured as disabled,
all incoming multicast paging calls will be automatically ignored when DND is activated in
phone mode. If the value of the parameter is the priority value, the incoming multicast paging
calls with higher or equal priority are automatically answered and the ones with lower priority
are ignored. The phone will automatically answer all incoming multicast paging calls when DND
is activated in custom mode. It is not applicable to CP860/CP920 IP phones.
Paging Priority Active
This parameter decides how the IP phone handles the incoming multicast paging calls when
there is already a multicast paging call in progress. If the value of the parameter is configured
as disabled, the IP phone will automatically ignore all incoming multicast paging calls. If the
value of the parameter is configured as enabled, an incoming multicast paging call with higher
priority or equal is automatically answered, and the one with lower priority is ignored.
