 Regulators often set different tariffs for domestically and internationally originating calls and thus there is a financial incentive to take an illegal action to profit from this tariff difference.On the sending side it looks like an international call, but on the receiving side it looks like a domestic call and settlement is done as if it was a local call.Re-origination or Refiling is the name given to the practice of substituting a new calling line identity (CLI) for the call at some point in its journey.
