Abstract: This system is an attempt to develop and advanced and clear understanding of the call record report. Call Detail Record (CDR) is a detailed record of all calls through the telephone exchange or any other means of communication. The record is kept by the telephone exchange involved and contains call details such as call time, call duration, source number and destination, call completion status, etc. CDRs are created by telephone billing systems. CDRs are saved by rotating the transmitter until the end of the call. CDRs can be used to support the operation of a telephone company by providing information about incorrect calls. Route traffic value estimates can also be obtained.
