Call Detail Record (CDR) Utility
The Call Detail Record (CDR) utility enables you to view summary information about conferences, and
retrieve full conference information and archive it to a file. The file can be used to produce reports or can be
exported to external billing programs.
The
Collaboration Server
can store details of up to 2000 conferences. When this number is exceeded, the
system overwrites conferences, starting with the earliest conference. To save the conferences’ information,
their data must be retrieved and archived. The frequency with which the archiving should be performed
depends on the volume of conferences run by the MCU.
The
Collaboration Server
displays Active Alarms before overwriting the older files, enabling the users to
backup the older files before they are deleted. The display of Active Alarms is controlled by the
ENABLE_CYCLIC_FILE_SYSTEM_ALARMS
system flag.
If the ENABLE_CYCLIC_FILE_SYSTEM_ALARMS is set to YES and a Cyclic File reaches a file storage
capacity limit, an Active Alarm is created: “Backup of CDR files is required”.
Each conference is a separate record in the MCU memory. Each conference is archived as a separate file.
Each conference CDR file contains general information about the conference, such as the conference
name, ID, start time and duration, as well as information about events occurring during the conference, such
as adding a new participant, disconnecting a participant or extending the length of the conference.
The CDR File Properties
The output of a CDR file depends on the format in which the file was archived and the size of the file.
CDR File Formats
The conference CDR records can be retrieved and archived in the following two formats:
●
Unformatted data
– Unformatted CDR files contain multiple records in “raw data” format. The first
record in each file contains general conference data. The remaining records contain event data, one
record for each event. Each record contains field values separated by commas. This data can be
transferred to an external program such as Microsoft Excel
for billing purposes. The following is a
sample of an unformatted CDR file.
Unformatted CDR File
The value of the fields that support Unicode values, such as the info fields, will be stored in the CDR
file in UTF8. The application that reads the CDR must support Unicode.
