Abstract: A fraud detection system is disclosed for telephone PBX calls. The system includes a fraud data server for buffering the call detail records relating to inbound 800 number calls and outbound international calls. A threshold manager is connected at its input to an output of the fraud data server for detecting numerical counts exceeding preselected threshold values, in predetermined fields of the call detail records, and generates an alarm. The output of the threshold manager is connected to an input of the fraud data server for buffering the alarm incident to respective call detail records. A computer workstation is connected to the fraud data server for receiving packets of call detail records relating to alarm data, in a filtered preselected format. The workstation includes a monitor for displaying the alarm data on a graphical interface.
