Introduction

FS PBX is a modern, enterprise-grade VoIP and unified communications platform built on top of FreeSWITCH®. It began as a fork of FusionPBX, then was redesigned from the ground up with new technologies such as Laravel, Vue.js, Tailwind, and modern APIs.

The result is a platform that maintains compatibility with the proven FusionPBX architecture, while delivering a cleaner interface, improved performance, and new features that meet the needs of today's telecom providers and enterprises.
