# Calls

Matrix supports two types of calls:

- Element Call powered by [MatrixRTC](https://half-shot.github.io/msc-crafter/#msc/4143) and [LiveKit](https://github.com/livekit/livekit)
- Legacy calls, sometimes using Jitsi

Both types of calls are supported by different sets of clients, but most clients are moving towards MatrixRTC / Element Call.

For either one to work correctly, you have to do some additional setup.

- For legacy calls to work, you need to set up a TURN/STUN server. [Read the TURN guide for tips on how to set up coturn](./calls/turn.mdx)
- For MatrixRTC / Element Call to work, you have to set up the LiveKit backend (foci). LiveKit also uses TURN/STUN to increase reliability - you can set up its built-in TURN server, or integrate with an existing one. [Read the LiveKit guide](./calls/livekit.mdx)
