FreeSWITCH

FreeSWITCH is the open-source engine developers rely on when they need deep control over real-time communications. It provides direct access to the media and signaling layers, a modular architecture, and flexible APIs for extending your system or integrating with the rest of your environment. Teams turn to FreeSWITCH to power their voice, video, and messaging platforms, but when the operational weight of scaling becomes too much, extend your workload to SignalWire without changing your application logic. FreeSWITCH 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. With over 5k+ businesses and 300M+ daily users globally, FreeSWITCH powers some of today's top businesses. It allows developers to build with confidence and provides the tools necessary for modern communication needs. SignalWire enhances FreeSWITCH by offering additional capabilities such as AI integration, automatic scaling, and global high availability, enabling businesses to focus on their core operations without the burden of managing complex telecom infrastructure.
