NginxAbout SignalWire
We started FreeSWITCH because we wanted to solve our own challenging problems. We could not find a stable, scalable way to implement our 2004 call center as a service product. DIY solutions were a collection of random tools with constant stability and maintenance issues; premade solutions were massively expensive and still required physical data centers anyway. We built FreeSWITCH on our vision of solving those problems, made a community, and used it for insight. This took us well beyond the original goal. FreeSWITCH became so ubiquitous that the world made many vertical products with it that generate billions of dollars a year. At SignalWire, we empower businesses with easy-to-use and customizable cloud communications tools. Programmable Unified Communications supplants one-size-fits-all solutions, sparking innovation and growth. We have harnessed the complexity of CPaaS UCaaS CCaaS and Voice AI and made the entire paradigm available to developers. Come talk to us and we can help you achieve your goals.
