Stephen Ornadel of inconectiv kindly presented at the March 2014 RAG meeting on the complicated but vital topic of international number range management. He explained how telcos are failing to implement basic and sensible controls over number ranges, or conversely blocking far more than they needed to. Straightforward improvements could significantly reduce the opportunities to exploit weaknesses in number ranges. Stephen backed up his analysis with a detailed examination of data about causes and types of fraud.
Stephen’s presentation was recorded, and subsequently made available as a podcast on Commsrisk. You can listen to it here.
