The Call Detail Record (CDR) Utility
17
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 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.
The Polycom RMX can store details of up to 2000 (RMX 1500/2000) or 4000 (RMX 4000)
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 RMX 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 (default setting when
ULTRA_SECURE_MODE System Flag 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.
