我想实现Audio＆amp;在Xamarin表单应用程序中使用IceLink和QB（Quick Blox）进行视频通话。
我从github下载了代码 - “https://github.com/QuickBlox/quickblox-dotnet-sdk/tree/frozen-samples”
登录和用户列表已成功运行，但是当我选择任何用户后开始视频通话时，它会显示错误：
Not connected to XMPP server
根据我的理解，
IceServer未连接或conference.RelayUsername”或conference.RelayPassword”不正确。现在，我用过 -
private string[] IceServers =
{
"stun.l.google.com:19302",
"turn.quickblox.com",
"turn.quickblox.com:3478?transport=udp",
"turn.quickblox.com:3478?transport=tcp",
"turnsingapor.quickblox.com:3478?transport=udp",
"turnsingapore.quickblox.com:3478?transport=tcp",
"turnireland.quickblox.com:3478?transport=udp",
"turnireland.quickblox.com:3478?transport=tcp"
};
conference.RelayUsername = "test";
conference.RelayPassword = "pa55w0rd!";
conference.ServerPort = 3478;
因此，请帮助我解决此错误，并为音频呼叫提供支持。
这是我的输出：
