An introduction to VoIP telecom fraud

VoIP is about convergence, saving money and resources. However, these types of systems also create more inroads for attack.

As VoIP has become more accessible and popular, security threats have grown as well. The most prevalent threats to today’s VoIP deployments are rooted in traditional data networking and PSTN attacks.

Today, VoIP devices are the primary tools used by fraudsters. In the first half of 2012, 46% of fraudulent calls were made from VoIP phones.

At TransNexus, we've recently posted a comprehensive whitepaper introducing the concepts of VoIP fraud on our website. The paper details fraud scenarios, including local routing number fraud, false answer supervision, and call transfer fraud.
