-This is a guide to set up server-side support for audio/video calls over XMPP. To do this we will first install and configure [coturn](https://github.com/coturn/coturn). It is a libre STUN/TURN server that helps establish peer connections across firewalls for media streams such as calls. Additionally we will configure Prosody to talk to `coturn`.
