What is FreeSWITCH?

FreeSWITCH is the leading open-source communication framework that powers some of the world's largest telephony infrastructures. It is maintained and sponsored by SignalWire, a company founded by the core developers of FreeSWITCH as an alternative solution for deploying software-defined telecom in the cloud. This provides you with options to architect and build with FreeSWITCH or, alternatively, to use SignalWire's low-code platform infrastructure to deploy quickly and easily. The choice is yours.

5,000+ commercial businesses use FreeSWITCH every day - globally.
