CDR

CDR is an abbreviation for the the term Call Detail Recording. It is the data that is submitted by your telephone system to a collection device linked to your call accounting package. The data contains particular information about every telephone call including date, time, duration, digits dialed and trunk line. Often the term SMDR (Station Message Detail Recording is used interchangeably with CDR). The "raw" information is generally interpreted and translated into a database for real time or scheduled processing and reporting.

We use CDR to examine telephone call activity
