SEP is used during signalling via w3c's recommended RTCPeerConnectionAPI interface to set up a multimedia session. The multimedia session description specifies the critical components of setting up a session between local and remote such as transport ports, protocol, profiles. It also handles the interaction with the ICE state machine.

TURN server for WebRTC – RFC5766-TURN , Coturn, Xirsys , Twillio
STUN (Session Traversal Utilities for NAT) and TURN (Traversal Using Relays around NAT) are protocols that can be used to provide NAT traversal for VoIP and WebRTC. These projects provide a VoIP media traffic NAT traversal server and gateway. TURN Server is a VoIP media traffic NAT traversal server and gateway. This article describes working … Continue reading TURN server for WebRTC – RFC5766-TURN , Coturn, Xirsys , Twillio
NAT traversal using STUN and TURN
STUN and TURN server protocols handle session initiations with handshakes between peers in different network environments . In case of a firewall blocking a STUN peer-to-peer connection, the system fallback to a TURN server which provides the necessary traversing mechanism through the NAT.
