我已经设置了一个Ubuntu 16.04 EC2 t2.medium服务器，并按照http://docs.bigbluebutton.org/2.0/20install.html中的说明安装BigBlueButton 2.0-beta。
当我登录演示会议室并选择麦克风时，它说呼叫... 然后更改为连接... 然后我收到一条消息说：< / p>
WebRTC音频失败
检测到以下WebRTC问题：错误1010：ICE协商 超时。你想尝试使用Flash吗？
以下是控制台的输出：

请检查您的防火墙：
答案 1 :(得分：0)
问题在于您的 sip ip 和端口。 首先检查 /opt/freeswitch/etc/freeswitch/sip_profiles/external.xml 设置。
ws 绑定：:5066 wss 绑定：:7443 改成这样：
ws-binding: your_external_ip_address:5066 wss 绑定：your_external_ip_address:7443 您的外部IP地址与external_sip_ip地址相同。
如果您使用防火墙，请检查您的 5066 和 7443 端口。
那别忘了重启bbb（bbb-conf --restart）
