A call detail record contains data fields that describe a specific instance of a telecommunication transaction, but does not include the content of that transaction. By way of simplistic example, a call detail record describing a particular phone call might include the phone numbers of both the calling and receiving parties, the start time, and duration of that call. In actual modern practice, call detail records are much more detailed, and contain attributes such as :
the phone number of the subscriber originating the call (calling party, A-party)
the phone number receiving the call (called party, B-party)
the starting time of the call (date and time)
the call duration
the billing phone number that is charged for the call
the identification of the telephone exchange or equipment writing the record.
