Telecommunications fraud is a global issue that has become even more pervasive with the growth in IP telephony and Voice over IP (VoIP) providers. It costs service providers and their customers billions of dollars annually. The TMT TeleShield service enables companies to take control of their strategy to win against fraudsters.
\nWith our TeleShield products, companies can ‘shield’ themselves from incurring losses from telephony fraud schemes. TMT provides unique access to real-time data through a robust network of suppliers combined with its own SS7 infrastructure enabling us to provide responses when other suppliers may be blocked by a network operator.
\nTeleShield provides intelligence on telephone numbers which can identify suspicious activity and enable service providers to make informed decisions to avoid financial impact or negative customer experience. For example, TeleShield provides information on:
\n\n - Has the number been made available for service by the regulator?\n\n - Does the number have a suspicious service type, for example is it a premium rate, satellite or VoIP?\n\n - Has the number been assigned to a subscriber by a service provider?\n\n - Has the number been ported?\n\n| Parameter | TeleShield Routing | TeleShield Fraud | TeleShield Enhanced Fraud |
