TransNexus Inc. (Booth 904) released NexOSS version 3.2, which offers automated least-cost and grade-of-service routing features. The new release enables VoIP carriers quickly and easily to build new wholesale VoIP products from hundreds of interconnect partners, said TransNexus. By using both rates and grade-of-service parameters, service providers can create different products for VoIP peering, interconnect and SIP trunking.

NexOSS accepts rate plans quoted in any format by NPA-NXX, by LATA and OCN, by LATA and tiers, or any other format. It uses the Telcordia LERG to normalize complex rate plans into a simple routing table with eight-digit routing, or more, to ensure the best routing destination for every call.

By optimizing least-cost routing (LCR) for interstate, intrastate and extended local calling (ELC) areas offered by multiple carriers, TransNexus customers can reduce their PSTN terminations fees by 25 percent or more, added the company.

The solution does not export a proprietary routing table to the service providers softswitch or session border controller. Instead, the service providers softswitch or session border controller queries the TransNexus route server through a standards-based interface. The function of the TransNexus route service is similar to the function of a service control point (SCP) in an SS7 network and enables scaling of very large routing tables that are not limited by softswitch or session border controller hardware.
