The fraud management system that would enable it address new types of fraud such as interconnect fraud - fraud and malpractice between communication service providers, Subex said in a filing with the Bombay Stock Exchange.

The Subex Azure Fraud Management Solution (SAFMS) is an advanced fraud management system, which enables telecom operators to detect both known patterns and unusual fraud types in all environments - wireline (PSTN, ISP, VoIP), wireless (2G, 2.5G, 3G) across all services (postpaid, prepaid, VAS, MMS, m-commerce).

SAFMS utilises rules-based alarms and artificial intelligence driven pattern matching to identify unusual behaviour. It is highly flexible allowing operators to customise the configuration to suit their network and business requirements.

"We are finding that many of our customers are now interested in addressing interconnect fraud. This deployment will bring a fresh approach to detect and manage inter-operator frauds in the region, with a particular benefit to the network deploying this solution - it is sure to improve their profitability," Dean Smith, president Asia-pacific at the company said.

Subex Azure Ltd, the world's largest vendor of revenue maximisation solutions for telecom operators, said average revenue leakage across global telecoms operators has increased to 12.1 per cent of turnover ($176 billion), compared to 11.6 per cent in 2005. This is one of the main findings of the fourth consecutive annual 'Operator Attitudes to Revenue Assurance 2006' report.
