The Data Filters
Example 1: To create a Data Filter Clue that will reject call records
received on Sunday, match parameters would be deﬁned as w=1. Where w
is the Real-Time variable for the day of the week, and 1 indicates Sunday.
Example 2: To create a Data Filter Clue that will reject call records
received after 6:00 PM (18:00) or before 7:00 am (07:00), match parameters
would be deﬁned as follows:
Where t is the Real-Time variable for the time of the day, and + is the
logical OR operator.
• Real-Time variables are not deﬁned in the Data Filter Format.
• Match parameters can include both Real-Time variables and
regular variables, as well as logical and relational operators.
• Real-Time variables function independently from the Time/Date
Stamp. The Time/Date Stamp does not have to be enabled in
order for the Real-Time variables to function.
• Values from the internal clock/calendar are not included in the
call record, unless the Time/Date Stamp is enabled.
8.6. Assigning the Data Filter to a Port
After the Data Filter is deﬁned, the next step is to assign the ﬁlter to one or
both of the two PBX inputs (serial PBX Input or PBX IP Port.) The port
conﬁguration menus are used to assign one of the two available Data Filters
to each port as described in Section 5.4. Note that Data Filters will not
function unless they are assigned to a port.
