SMDR (Station Message Detail Record)

A detailed record of incoming and outgoing calling activ-

ity generated by a Centrex system, key telephone system (KTS), or PBX. These records provide a call accounting system with the data necessary to generate reports for purposes such as client billback, cost allocation, cost control, and fraud detection. SMDR data typically includes the originating or target telephone number and station number, the time of day the call originated and terminated or the total elapsed time of the call, the access code used, the line or trunk employed, and the account code, if any. Synonymous with call detail record (CDR).
