The MCU is able to generate Call Detail Records (CDR) which may be used for auditing and billing purposes. When logging is enabled, records are generated whenever a conference starts or finishes, when participants join and leave conferences and so forth.
To use the CDR feature, there must be a 256 Mb compact flash card in the slot in the front of the unit. If there is no compact flash card present, and you have enabled CDR logging, errors will be recorded in the Event log.
When enabled, the CDR log is stored on the compact flash card and displayed on the 
page. You can either view the CDR log on that page, or you can download it as an XML file. You cannot read from the compact flash card using any device other than the MCU.
When enabled, CDRs are flushed to the compact flash card every five minutes; when the card is full, the oldest logs are overwritten.
To view and control the CDR log, go to and click the tab. Refer to the tables below for details of the options available and for a description of the information displayed.
