Calling Line Identity (CLI) spoofing or Caller ID spoofing is a source of many large scams around the world that involve fraudulent activity against consumers, damages corporate reputation and impacts service providers’ revenues.
CLI spoofing allows the scammer to disguise their identity by deliberately changing the telephone number and/or name relayed as the Caller ID information. This enables them to pretend to be the bank, the government, a reputable private company, or a local number.
Service providers are losing out on termination and interconnect revenues from CLI spoofing as international traffic is spoofed to represent cheaper country rates.
