Alteva offers Broadsoft-based Class 5 cloud-based UC solutions to businesses via channel partners, and resells its platform to other carriers at wholesale. It also offers class 4 origination and termination service for carriers. Previously, Alteva was using a static LCR system for carrier origination and termination business. It generated a static LCR table, limited to six-digit dial codes, and exported it directly to Alteva’s softswitch. That meant that it was slow to update routing changes and could not eliminate unprofitable routes. Alteva needed a dynamic LCR engine that could be updated in real time and ensure that every route was profitable.
Alteva made the decision to switch to TransNexus’s next generation least cost routing solution, utilizing NexOSS software and OSPrey route servers. NexOSS is a centralized application for provisioning routes and rating Call Detail Records (CDRs). LCR configurations are replicated from NexOSS to OSPrey. Alteva’s Sonus softswitch then routes calls to OSPrey, which determines the least-cost routing and then sends a SIP invite back to the switch with lowest cost routing instructions.
By keeping the LCR table on a routing server, rather than directly on the switch, Alteva can dynamically update multiple routing tables with millions of possible no-loss routes. The routing server automatically updates in real-time as rate changes occur in the billing system. NexOSS enables centralized routing control of distributed OSPrey routing servers that can serve both wholesale and retail business units with different softswitches.
NexOSS software also has a built-in number portability module and the ability to host the North American Number Portability Database (NPAC). It collects CDRs as calls are completed, and creates detailed reports for near real-time margin analysis. Those reports show origination fees, termination fees, and gross profits by customer, product, provider, time of day and dial code.
Also, Alteva said that NexOSS adds a layer of protection against VoIP fraud. By analyzing the CDRs and routing requests, NexOSS can detect fraudulent activity and send Alteva’s engineers automatic email and SNMP alarms. It may also temporarily suspend the suspicious route from the routing table, effectively stopping the fraud event before Alteva starts losing money.
