Free Trial ButtonNexOSS-FC is a telecom fraud management system that uses SIP Analytics to detect fraudulent calling trends before calls are made. NexOSS-FC scores each SIP INVITE for fraud potential before it enters your network. SIP Analytics uses the same techniques as CDR analytics, such as historical analysis and adaptive learning. However, SIP Analytics is much faster and uses SIP header information, not available in CDRs, for smarter fraud detection with fewer false positives.


How It Works

NexOSS-FC can complement any Session Border Controller (SBC) or softswitch and can provide fraud detection for any SIP device. When a SIP call arrives at the SBC, the SBC forwards the call to NexOSS-FC. NexOSS-FC responds in less than a millisecond with instructions to route the call as normal, block the call, or divert the call.
