Sipwise

In 2008, a group of telecommunications professionals in Austria recognized a critical gap in the market: traditional telecom switching infrastructure was expensive, rigid, and difficult to scale. They set out to build something different - an open-source based communication platform that could rival proprietary systems while offering the flexibility and cost-efficiency that modern telecom operators and ISPs needed. Thus, Sipwise was born with the mission to revolutionize how communication service providers deliver voice, video, and unified communication services.

Today, Sipwise has grown into a global leader in telecom software solutions, developing the acclaimed C5 Next Generation Communication Platform (NGCP) - a carrier-grade VoIP softswitch that supports voice, video, presence, messaging, and WebRTC. The company has made significant contributions to industry-standard open-source SIP software, including the widely-used Kamailio and RTPengine projects. Sipwise empowers telecom operators and internet service providers worldwide, offering solutions for B2B unified communications, residential VoIP services, SIP trunking, and cloud-based enterprise communication platforms. With a team of international professionals and a commitment to innovation, Sipwise continues to shape the future of telecommunications from its headquarters in Vienna, Austria.
