Bypass Fraud is used to describe the use of various least cost call termination techniques like SIM Boxes, Leakey (hacked) PBXs etc. to bypass the legal call interconnection and diverting international incoming calls to ‘on’ or ‘o­ ’ network GSM/CDMA/Fixed calls through the use of VoIP or Satellite gateway, thus evading revenue for international call termination which operators and government regulators are entitled to.
