/**
 * <p>Gets the Interactive Connectivity Establishment (ICE) server configuration
 *             information, including URIs, username, and password which can be used to configure the
 *             WebRTC connection. The ICE component uses this configuration information to setup the
 *             WebRTC connection, including authenticating with the Traversal Using Relays around NAT
 *             (TURN) relay server. </p>
 *         <p>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 href="https://tools.ietf.org/html/draft-uberti-rtcweb-turn-rest-00">A REST API For
 *                 Access To TURN Services</a>.</p>
 *         <p> 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.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { KinesisVideoSignalingClient, GetIceServerConfigCommand } from "@aws-sdk/client-kinesis-video-signaling"; // ES Modules import
 * // const { KinesisVideoSignalingClient, GetIceServerConfigCommand } = require("@aws-sdk/client-kinesis-video-signaling"); // CommonJS import
 * // import type { KinesisVideoSignalingClientConfig } from "@aws-sdk/client-kinesis-video-signaling";
 * const config = {}; // type is KinesisVideoSignalingClientConfig
 * const client = new KinesisVideoSignalingClient(config);
 * const input = { // GetIceServerConfigRequest
 *   ChannelARN: "STRING_VALUE", // required
 *   ClientId: "STRING_VALUE",
 *   Service: "TURN",
 *   Username: "STRING_VALUE",
 * };
 * const command = new GetIceServerConfigCommand(input);
 * const response = await client.send(command);
 * // { // GetIceServerConfigResponse
 * //   IceServerList: [ // IceServerList
 * //     { // IceServer
 * //       Uris: [ // Uris
 * //         "STRING_VALUE",
 * //       ],
 * //       Username: "STRING_VALUE",
 * //       Password: "STRING_VALUE",
 * //       Ttl: Number("int"),
 * //     },
 * //   ],
 * // };
