Xmpp 在Xamarin表单应用程序中使用Icelink和QB（快速Blox）支持音频/视频

我想在Xamarin表单应用程序中使用IceLink和QB（快速Blox）实现音频和视频通话

我已经从github下载了代码- “”

登录和用户列表已成功工作，但当我在选择任何用户后启动视频通话时，显示错误：

根据我的理解，也是这样

• IceServer

  未连接或
• “

  conference.RelayUsername

  ”或
• “

  会议.RelayPassword

  ”不正确

现在，我用-

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，请帮助我如何解决此错误，并为音频呼叫提供支持
