О проекте

PortaOne creates software solutions enabling telecommunication service providers and carriers to offer multiple voice, data, and converged services on a single platform named PortaSwitch.
PortaOne products are built around a converged carrier-grade billing platform combined with a class 4-5 SIP softswitch and media applications for conferencing, IVR and unified messaging.
Our billing is RADIUS based and compatible with major SBC and media gateway vendors. It can process real time prepaid and postpaid charges for voice and video calls, Internet connectivity, MVNO and IPTV services, WiFi/WiMAX access, data and faxes, or one-time events such as SMS or a pay-per-view movie.
PortaSwitch is a unified platform for telecommunication service providers, wholesale carriers, ISP, MVNO and NGN operators for unifying voice, messaging, and data traffic within a single converged network.
PortaSwitch provides various prepaid, postpaid, retail and wholesale telecommunication services, including calling cards, Vonage- and Skype-like services, CLEC type services, MVNO & MVNE, ISP, WiMAX & WiFi and much more. It includes 2 main components:
PortaBilling, a business and operation support system (B/OSS) designed for telecommunication service providers to manage end-to-end telecom service networks.
PortaSIP is a clusterable and highly scalable SIP softswitch of class 4 and class 5 with media application that plays IVR (voice prompts). It offers a variety of both advanced class 5 features for hosted IPPBX or IP Centrex services as well as the majority of functionality normally attributed to session border controllers (SBC).
