SIM-card blocked by Anti-Fraud systems is the most urgent problem for entrepreneurs who invest in VoIP GSM termination. Cellular operators use expensive systems to track re-filing.
There are many specialized solutions for detecting termination and other types of fraud on communication networks. When suspicious activity is detected, the system blocks SIM-cards installed in the GSM gateway or ata voip gateway. But not every operator can afford to purchase and implement such solutions because they are expensive and pay off in about a year. Therefore, they are mostly used by large cellular companies with a large subscriber base. Moreover, the very process of introducing anti-fraud systems is complex and protracted. It can take from six to fifteen months.
The most popular fraud detection solutions used by operators are:
HP is one of the oldest antifraud systems on the market. Hewlett Packard released the first version of the program in 1993. After that, the product was improved, and to date it is used by about 70 GSM operators in the world. The system is built on a modular basis, so it quickly adapts to prevent new types of fraud by adding modules.
A new solution from HP, which includes 2 components - Revenue Analyzer (profitability improvement system) and Credit Management System. Representatives of the company claim that the use of this system allows you to return about 50-70% of the profit lost due to termination. According to them, operators lose about 60 billion dollars annually.
The solution from the British company Neural Technologies, is a comprehensive product to protect against various types of fraud, including gray traffic termination.
The analytical system can work together with information systems of the cellular company. Using billing data, etc., it generates analytical reports. Termination is detected in real time.
In general, fraud detection systems are effective only in 50% of cases. The annual losses of GSM operators confirm this fact. It is quite real to make money doing termination by installing gateways and goip freepbx. The main thing is to use SIM-cards of the operator that use a loyal antifraud and also efficiently mask them, simulating the behavior of the real subscriber.
