我使用了带有两个Chrome标签的WebRTC视频会议（这意味着我称呼自己）。一切正常。
我也使用了WebRTC视频会议和两台不同的笔记本电脑，如果这些笔记本电脑在同一网络上。我在代理后面使用了我办公室的网络。
但是，如果我将WebRTC视频会议与Office Network上的一台笔记本电脑一起使用，而在Personal Home网络上与另一台笔记本电脑一起使用，则无法使用。
这是scaledrone中此代码的实时示例，带有通道代码sX5nWDp8dfyEysqhLive example从这里回购repo 这是代码

</html>是，但是您需要一个STUN服务器（在iceServers配置中使用该服务器），并且两个网络都需要允许UDP流量。以我的经验，办公室网络偶尔会在某些端口范围（例如，除DNS之外的所有端口）上阻止UDP流量。
要使用已知工作的客户端测试WebRTC，请尝试使用AppRTC video chat client 中的WebRTC Samples。如果这不起作用，则应检查办公室防火墙上的UDP规则。否则，您将需要TURN服务器。
