Information Technology Reference
In-Depth Information
Configure the dial-plan to match local calling pattern so that CDRs are interpreted
correctly (for example, 4-digit calls are classified as On Net and 10-digit calls are lo-
cal). The default settings are based on the NANP.
■
Configure the
gateways
in the CAR tool. Gateways configured in CUCM are auto-
matically added and deleted, but the area codes local to the gateway must be added
so that the reports can determine which calls are long distance.
■
Set the
COMPANY_NAME
value (maximum of 64 characters) as desired; this name
appears in the header of CAR reports.
■
Set up the
CAR Scheduler
to control which types of records are loaded, at what in-
tervals, and for how long. The aim is to allow sufficient loading time while not impact-
ing the server performance. Loading the CDR and CMR file should not be confused
with the actual generation of the CDRs and CMRs; loading refers to the Repository
node pulling the raw CDR/CMR data from the call processing nodes into the
CDR/CAR database.
■
Configure CDR/CAR database purging.
Automatic Purge
is on by default; you can
adjust the
High
and
Low Water Mark
values to control when the purging begins and
stops, based on the percentage utilization of the available database disk space. Which
records to purge is based on the age of the records.
Manual Purging
is also available.
■
Configure Automatic Report Generation. Choose which reports should be automati-
cally generated and optionally select whether you would like the reports emailed. The
interval for report generation is fixed (daily, weekly, or monthly), but the start time
can be customized using the Scheduler interface.
■
Exporting CDR and CMR Records
CDR and CMR files can be downloaded from the server as a CSV file, typically to be im-
ported into a billing application. The steps are as follows:
1.
From the CAR tool, navigate to
CDR
>
Export CDR/CMR
.
2.
Set the
From Date
and
To D a t e
values.
3.
In
Select Records
, check
CDR Records
,
CMR Records
, or both.
4.
Click
Export File
.
5.
In the new window, choose either
CDR Dump
or
CMR Dump
, and then click
Save
As
to select a file location on the workstation.
6.
Selecting the
Delete File
checkbox causes the CAR tool to delete the downloaded
records from the CAR database. This is recommended to prevent the database size
from ballooning unnecessarily.
Generating CDR Reports
As mentioned previously, users, Managers, and Administrators can use the CAR report
tool to generate different reports. This section discusses the reports in more detail.
