8. The Data Filters
The Data Filters allow you to make the most efﬁcient use of the VIP's
memory by excluding records (such as inbound calls) that are not needed
for your call accounting application. When the Data Filters are correctly
conﬁgured, the VIP will monitor each record received from the PBX.
Records that do not meet the user-deﬁned criteria will not be stored.
The conﬁguration procedure consists of three tasks:
• Deﬁne the Data Filter Format
• Deﬁne the Data Filter Parameters
• Enable the Data Filter
The VIP features two separate Data Filters. Each ﬁlter has its own format,
variables, and storage criteria. When two dissimilar PBX units are
connected to the VIP, this provides a separate Data Filter for each PBX.
• When the VIP is connected to two different types of PBX units, it
is recommended to deﬁne a separate Data Filter for each PBX.
• A Data Filter that is deﬁned for one PBX may not function with
another type of PBX. For example, a Data Filter deﬁned for
the PBX connected to Port A, may not function correctly when
assigned to a different type of PBX connected to Port B.
Each Data Filter Consists of a "Format" and one or more "Clues". The
Format assigns variables to individual call record locations; Clues deﬁne
the parameters that will be used as the criteria for rejection or storage of
each call record.
8.1. The Data Filter Configuration Menus
To access the Data Filter Conﬁguration Menus, from the Main Menu,
type 26 and press [Enter]. A selector menu will appear. Type 1 for Data
Filter 1, or 2 for Data Filter 2, and then press [Enter]. The Data Filter
Conﬁguration Menus (Figure 8.1) offer the following options:
1. Data Filter Action: Determines whether the Filter will store or reject
records that match Clues. If the Data Filter Action is "Reject", the
VIP will reject all records that match Data Filter Clues. If the action is
"Store", the VIP will store all records that match Clues.
