О проекте

PortaOne is a leading global software developer for modern telecoms. The company’s billing (B/OSS & OCS) and switching (SBC & Class 4/5) products enable telecommunication service providers and carriers to run a broad line of retail, enterprise, SME, and wholesale services on a single integrated software platform.

Over two-thirds of 300 PortaOne staff are support engineers providing the best-in-industry 24/7 technical support services for clients involved in hosted IP PBX and SIP trunking services, calling cards and wholesale VoIP, IPTV and residential triple-play, MVNO and MVNE, SMS, data and voice over LTE, and more.

PortaOne’s flagship platform, PortaSwitch is a fundamental part of the business infrastructure for well over 400 service providers and telcos in ~90 countries worldwide. It consists of 2 components:

— PortaBilling, a business and operation support system (B/OSS) designed for telecommunication service providers to manage end-to-end telecom service networks. It is RADIUS/Diameter based and compatible with major SBC and media gateway vendors. PortaBilling can process real time prepaid and postpaid charges for voice and video calls, Internet connectivity, IPTV services, WiFi/WiMAX access, data and faxes, or one-time events such as SMS or a pay-per-view movie.

— 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 services as well as the majority of functionality normally attributed to session border controllers (SBC).
