With the following CallXML scripts you can help telcos to fight with various types of international bypass fraud:
  • Over-the-top (OTT) bypass fraud: vendors of mobile applications like Viber, Whatsapp, other mobile VoIP dialers cooperate with wholesalers to bypass high rates of international termination. Termination over the top (over IP protocol) is almost free for the application vendors. Having the applications installed on a high percentage of mobile phones all over the world, the vendors use the applications to terminate international calls: more and more people see international calls going to their phones via Viber, when it is turned on.
  • GSM VoIP termination (grey routes) international bypass fraud: people all over the world have VoIP-GSM gateways (aka SIM boxes) terminating international (high-cost) calls at local (low) rates
