Telecom Fraud:

A Hidden Challenge

From Early Charging Fraud to OTT Fraud, discover how these common types of fraud can impact your business
and how Razor’s iTest Voice can detect and prevent them.

FAS / Early Charging Fraud

This fraud involves operators answering the call themselves, playing a fake ringtone, and charging for it. In some instances, the call may be connected later, making it hard to detect. This can add up to 30 seconds of charge time per call.

Call Hijacking

The operator answers the call using a voicemail system or other recording, but doesn’t connect the call to the intended recipient. The caller is charged for the entire duration of the hijacked call.

OTT Fraud (Over The Top)

The operator bypasses the intended Mobile Network Operator (MNO) and connects the call through a third-party application like Viber or WhatsApp, avoiding connection fees but charging the total cost.

Early Charging FAS

Similar to FAS/Early Charging Fraud, this involves charging during a non-chargeable part of the call, such as during the ringtone. It’s a subtle way to inflate call costs.

Call Hijacking Variants

Variants of call hijacking might include Fake Voicemail messages, network messages, or echoes. These can lead to calls not reaching the intended recipient while still incurring charges.

Late Charging FAS / Call Stretching

Here, the operator delays sending the disconnect, keeping the line open longer, and charging for additional connected time. This can add an extra 30 seconds of charge time per call.

Call Looping

This occurs when there’s an echo partway through a conversation, creating confusion, leading to termination, and redialing. This generates extra call length and results in a second chargeable call.

Dead Air Fraud

This fraud involves no sound being passed during a call, possibly due to intentional disruption. It might be used in conjunction with other fraud types to confuse or mislead.

Late Charging FAS

This entails delaying the disconnect to extend the chargeable part of the call. It’s often used in tandem with call stretching to further increase costs.

OTT Fraud Variations

Different versions of OTT Fraud might involve various third-party applications, all aiming to bypass the official MNO and thus avoid fees while still charging the caller.

Razor’s advanced detection mechanisms are designed to identify and mitigate these types of fraud, helping businesses maintain integrity in their voice traffic and avoid unnecessary costs.
