## What it is
FreeSWITCH is an open-source software-defined telecom stack that turns commodity servers into a full telephony platform for voice, video, and messaging. It handles call routing, media transcoding, protocol interconnection (SIP, WebRTC, PSTN), and programmable call control at carrier scale.

## Use cases
- run my own voip pbx server
- build a sip-based call routing system
- host video conferencing on my own infrastructure
- build an ivr phone system
- bridge webrtc calls with the pstn
- transcode audio between telephony codecs
- build a programmable voice api platform
- set up a softswitch on a raspberry pi

## When to choose
- you need carrier-grade voice/video call routing and media handling on your own servers
- you want protocol interop between SIP, WebRTC, and PSTN
- you need a self-hosted alternative to proprietary telecom switches or Twilio-style APIs
- you're building contact centers, IVRs, or telecom products at scale

## When to avoid
- you only need simple peer-to-peer calling without server-side call control
- you want a fully managed hosted API with no infrastructure to run
- your team cannot manage complex C-based telecom server configuration
- you need a lightweight embedded voice stack rather than a full switch
