TransNexus solutions
Telecom fraud management and fraud detection solutions
TransNexus solutions effectively eliminate the problems of traffic pumping fraud, PBX hacking, revenue sharing fraud, blind transfers, and call forwarding fraud for VoIP providers. The solution is to include smart monitoring features that sense when there is an unusual spike in call traffic to a specific destination. When a suspicious spike occurs, the TransNexus system simply and automatically blacklists the route, ensuring that fraud losses are kept to an absolute minimum without interrupting legitimate calls.
TransNexus has developed several fraud detection and prevention solutions that are compatible with Audio Codes, Broadworks, Cisco Call Manager, Metaswitch CFS and Perimeta, Oracle Acme Packet, Sansay, Sonus and Taqua platforms.
NexOSS-FC is a fraud prevention and detection solution that uses SIP Analytics™ to detect fraudulent calling trends before calls are made. The TransNexus NexOSS-FC solution scores each SIP Invite for fraud potential before it enters your network. SIP Analytics™ uses the same techniques as CDR analytics, but is much faster and uses SIP header information, not available in CDRs, for smarter fraud detection with fewer false positives.
SDReporter is a complete fraud detection and call detail record (CDR) reporting and analysis solution. Designed to be simple and efficient, SDReporter is easy to install and provides comprehensive telecom fraud, call completion, and Quality of Service (QoS) reports and alarms. Other fraud detection features include fraud blacklists, fraud scoring, call diversion, and call blocking.
Shield is a comprehensive blacklist containing a combination of premium rate number providers, known international premium rate number ranges, and industry sources. This solution is integrated in NexOSS-FC, NexOSS, and SDReporter.
Telecom Least Cost Routing
Least Cost Routing, or LCR, is a simple practice that finds the most inexpensive way to route phone calls. It is the process of analyzing, selecting and directing the path of outbound and inbound communications traffic, depending on which path delivers the best rates.
TransNexus has developed an industry-leading and innovative least cost routing solution that is compatible with Audio Codes, Broadworks, Cisco Call Manager, Metaswitch CFS and Perimeta, Oracle Acme Packet, Sansay, Sonus and Taqua platforms. It has also been the recipient of the INTERNET TELEPHONY Product of the Year Award for two consecutive years.
The TransNexus NexOSS solution saves VoIP service providers time and money with intelligent routing solutions and offers complete Call Detail Record (CDR) reporting and analysis. The NexOSS VoIP Routing, Operations, and Billing Support System is a suite of integrated back office applications which complement the operation of OSPrey Route Servers. NexOSS provides VoIP operators with an easy to use web interface for provisioning routes, rates, number translation rules and monitoring traffic analysis and billing reports. The TransNexus NexOSS solution also provides fraud detection.
White papers and resources
TransNexus has published a series of white papers and resources covering a variety of topics such as telecom fraud, the telecommunication industry, configuration guides, VoIP peering and settlements, Asterisk, OSP peering protocol, and OpenSIPS, OpenSER, Kamailio, SIP Router & SER.

Evolution of VoIP peering
In the beginning of the Internet, IP networks interconnected through public peering points such as Metropolitan Area Ethernet (MAE) East located on Washington DC or MAE West located in San Francisco. These public peering points soon became overwhelmed by the growing amount of data traffic being exchanged between IP networks. To address this problem, private data network operators began to privately interconnect (peer) their networks.
As VoIP technology developed, it was first deployed as a technology to bypass toll charges of the long distance telephone networks or Public Switched Telephone Network (PSTN). VoIP networks were stand alone networks interconnected only with the PSTN. VoIP peering, however, is the growing practice of directly interconnecting VoIP networks.
TransNexus, along with Cisco, 3Com and others was the creator of the ETSI Open settlement protocol (OSP). The OSP protocol is global standard for enabling secure peer to peer VoIP routing and accounting without the need of an intermediary device, such as a proxy, session border controller or Back to Back User Agent (B2BUA), in the VoIP signaling path. OSP peering is a general technique which may be used for any VoIP protocol (i.e. H323, SIP or IAX) and other IP communication transactions such as video, file sharing or short messaging.
