Buyer’s Guide
Buyer’s Guide
This guide provides the questions you need to ask and key takeaways you need to consider to choose the right solution for protecting against Caller ID (CLI) spoofing. It helps you determine your needs, shortlist vendors, and avoid common pitfalls.
MNOs face the challenge of mitigating the damage caused by a broad range of voice threats and frauds such as Spoofed numbers, Wangiri calls, Flash calls and SIM Box (Interconnect Bypass).
Caller ID spoofing is a technique where a caller deliberately falsifies the phone number and/or name displayed on the recipient’s caller ID. It is often used by scammers to impersonate trusted organizations, hide their identity, or make calls appear local. It is commonly associated with fraud, phishing, and phone-based scams. In many countries, regulators mandate operators to detect and block spoofed calls.
International Revenue Share Fraud (IRSF) is a telecom scam where fraudsters generate calls to premium-rate international numbers they control, earning a share of the revenue from call charges. Wangiri is a common form of IRSF, where scammers place missed calls that prompt victims to call back, connecting them to expensive premium numbers and generating fraudulent revenue.
Flash calls can represent missed revenue opportunities for mobile network operators. Instead of sending paid SMS messages for verification, some apps trigger a very short call that automatically confirms a user’s phone number. Because these calls often last only a second, operators earn little or no revenue, reducing potential income from traditional SMS-based authentication services.
SIM box fraud (interconnect bypass) is a telecom scam where criminals use devices called SIM boxes to route international calls through local SIM cards. This bypasses official international gateways, reducing call costs for fraudsters. Telecom operators lose revenue because calls appear local instead of international. It is commonly used by illegal call centers and organized telecom fraud groups.
