TURN server developed by the team behind Jitsi. TURN (RFC 5766) provides a standardised solution for VoIP applications to find the most efficient way to route media streams when NAT and firewall devices may be present.

The TurnServer project aims to be compliant with the TURN and STUN Request For Comments (respectively RFC 5766 and RFC 5389). It also support RFC 6156 namely TURN-IPV6 (relay between IPv4-IPv6, IPv6-IPv4 and IPv6-IPv6 addresses) and RFC 6062 namely TURN-TCP (relay data with TCP).
