//
// TURN is a protocol that is used to improve the connectivity of peer-to-peer
// applications. By providing a cloud-based relay service, TURN ensures that
// a connection can be established even when one or more peers are incapable
// of a direct peer-to-peer connection. For more information, see A REST API
// For Access To TURN Services (https://tools.ietf.org/html/draft-uberti-rtcweb-turn-rest-00).
//
// You can invoke this API to establish a fallback mechanism in case either
// of the peers is unable to establish a direct peer-to-peer connection over
// a signaling channel. You must specify either a signaling channel ARN or the
// client ID in order to invoke this API.
