In some cases as many as 50% of all international calls are being terminated through VoIP rather than as a direct telephone to telephone call.

• Provides network operators with capability to remove OTT bypass from networks as part of its bypass suite of fraud detection software

• OTT fraud accounting for up to 45% of traffic on certain routes

• More than 25% of international calls terminating as OTT

Anti-fraud and revenue protection specialist Revector has launched a new extension to its bypass suite of software for fixed line and mobile operators that protects call termination revenues from so called Over The Top (OTT) companies such as Viber and WhatsApp.

In recent months Revector has identified thousands of instances of calls originated as mobile to mobile voice calls being connected within Voice Over IP (VoIP) apps on mobile devices. In some cases as many as 50% of all international calls are being terminated through VoIP rather than as a direct telephone to telephone call.

This practice, known as OTT Bypass not only impacts on the potential call quality but also means users do not have access to standard telephony services such as voicemail and call forwarding, this practice is severely impacting the revenues of telecommunications operators that would usually be paid to connect the call.

Revector has now launched a revenue protection tool for fixed and mobile networks that enables them to detect and eliminate OTT Bypass quickly and effectively, ensuring that customers receive the quality of telephone they would expect from a direct dial voice call and protecting operator revenues.

Andy Gent, CEO of Revector comments: “Several OTT companies are proactively touting low cost calls on the open market to try to generate revenues from legitimately licenced telecommunications service providers. Essentially they are defrauding both the user, who expects their call to be carried as a legitimate call not over a VoIP app, and the legitimate telecommunications service provider who has paid a licence fee to terminate calls in country. This is sharp practice and impacts telecommunications companies’ abilities to maintain a profitable network.”

Revector’s solution identifies and manages the OTT call to protect the end user from poor quality calls and to ensure that operators collect the revenues to which they are entitled.

“OTT is just one of a number of ways in which companies are trying to tap in to telecommunications companies’ ability to generate revenues,” continues Gent. “Not only does that mean the telecommunications service providers are trying to compete with companies that do not have to provide a physical network, it also means end users are being duped into paying for a traditional phone call that they could have placed for free.”

Notes for editors on fraud techniques

Bypass, including interconnect and GSM gateway or SIM box fraud, occurs when the cost of terminating national or international calls exceeds the cost of a local mobile to mobile call in a particular country. Individuals and organisations buy multiple SIM cards and sell capacity to terminate calls on the open market. This leads to lost revenues for mobile network operators. SIM box fraud is illegal since those who undertake it are not licensed to provide telecommunications services in the country. Consumers will be unaware that their call is being routed via a SIM box but may experience a reduced quality of call or a reduction in telecommunications services, such as caller line identity.
