## What it is
Baresip is a portable and modular SIP User-Agent written in C with audio and video call support. It provides a rich feature set including multiple SIP accounts, call handling, encryption (TLS, SRTP, ZRTP), and a wide range of audio/video codecs and drivers.

## Use cases
- make voip calls from the command line
- build a custom sip softphone
- embed a sip user-agent into another application
- test sip infrastructure and pbx systems
- make encrypted audio and video calls over sip
- run a headless sip client on a server

## When to avoid
- you want a polished graphical softphone for end users
- you need a web-based calling solution rather than a native client
- you prefer a higher-level language or framework for rapid development
