TransNexus, Inc. is a software development company specializing in applications for managing large wholesale VoIP networks. TransNexus has been a pioneer in VoIP clearing and settlement technology since its founding in 1997. Initially, TransNexus was a VoIP clearinghouse providing interconnect routing, settlement billing and financial settlement among VoIP carriers. In 1998, TransNexus lead the VoIP industry with Cisco and 3Com by establishing the ETSI Open Settlement Protocol (OSP) – the international standard for secure routing and accounting of inter-domain IP transactions. In 2001 TransNexus divested its VoIP clearinghouse service to focus solely on providing software solutions for VoIP routing, accounting and security.
TransNexus provides its Operations and Billing Support System (OSS/BSS) software platform to major VoIP carriers worldwide including VerizonBusiness, NTT, Chungwha Telecom, Telkom Indonesia, and others. Important carrier features offered by TransNexus are least cost routing, number portability, profitability analysis and QoS controls. TransNexus is an active contributor to open source software projects and only offers software products based on open standards. While TransNexus maintains interoperability partnerships with strategic vendors such as Acme Packet, Cisco and MetaSwitch, the TransNexus solution is interoperable with any SIP based VoIP system.
TransNexus is a 2000 graduate of the Advanced Technology Development Center at the Georgia Institute of Technology. TransNexus, located in Atlanta, Georgia, is a privately held Delaware C corporation.
