About:
FreeSWITCH is a scalable open-source telephony platform designed to route and mediate audio, video, and text communications. It supports a wide array of protocols including SIP, WebRTC, and PSTN, enabling the creation of custom communication applications. Its modular architecture allows developers to build high-performance PBX systems, IVRs, and conferencing servers.
Key Features:
  • Scalable soft PBX and B2BUA
  • Support for SIP, WebRTC, H.323, and more
  • Programmable via Lua, JavaScript, and Python
  • Advanced IVR and conferencing capabilities
Use Cases:
  • Building custom PBX and VoIP services
  • Creating interactive voice response (IVR) systems
  • Hosting large-scale audio/video conferences
Alternatives:
  • Asterisk – Asterisk is older and uses a monolithic dialplan, whereas FreeSWITCH is modular and designed for high concurrency.
  • Kamailio – Kamailio is a SIP proxy/registrar focused on routing, while FreeSWITCH handles media and session management.
