Hi Hardi,

We just updated how webRTC connects to reduce the connection time.  Doing this changed
how the client connects and you need to make two corresponding changes to FreeSWITCH
configuration if your building the client on Master.  

See this enhancement for details

Check out the documentation at

  https://code.google.com/p/bigbluebutton/wiki/090InstallationUbuntu#Client_WebRTC_Error_Codes

For reasons why this error occurs.  In short, it's likely a firewall issue between
the user and the BigBlueButton server, not an issue with BigBlueButton itself.

I'm writing this to help those who still not figred out hot to resolve this issue.
You need to perform one extra steps when server is behind NAT(network address translation).
You need to configre Kurento to use stun server, which you can get from the link kurento documentation,
you need to edit /etc/kurento/modules/kurento/WebRtcEndpoint.conf.ini and uncomment and assign values for stunServerAddress and stunServerPort.

For example, to use the STUN server at 64.233.177.127 with port 19302, edit the lines with stunServerAddress and stunServerPort as follows:

stunServerAddress=64.233.177.127
stunServerPort=19302

Next, this is very important

edit /opt/freeswitch/conf/sip_profiles/external.xml and ensure the value for wss-binding uses the external IP address

<param name="wss-binding" value="EXTERNAL_IP_ADDRESS:7443"/>
At this point, restart your BigBlueButton server with bbb-conf --restart, then try connecting to the WebRTC media again.

If the issue stile not resolved then edit the following files and substitute EXTERNAL_IP_ADDRESS for the external IP address (not the external hostname).

Edit /opt/freeswitch/conf/vars.xml, and
change <X-PRE-PROCESS cmd="set" data="external_rtp_ip=stun:stun.freeswitch.org"/>
To <X-PRE-PROCESS cmd="set" data="external_rtp_ip=EXTERNAL_IP_ADDRESS"/>

Change <X-PRE-PROCESS cmd="set" data="external_sip_ip=stun:stun.freeswitch.org"/>
To <X-PRE-PROCESS cmd="set" data="external_sip_ip=EXTERNAL_IP_ADDRESS"/>

Next, edit /opt/freeswitch/conf/sip_profiles/external.xml and change
<param name="ext-rtp-ip" value="$${local_ip_v4}"/>
<param name="ext-sip-ip" value="$${local_ip_v4}"/>
to
<param name="ext-rtp-ip" value="$${external_rtp_ip}"/>
<param name="ext-sip-ip" value="$${external_sip_ip}"/>

Next, edit /usr/share/red5/webapps/sip/WEB-INF/bigbluebutton-sip.properties, and make sure the values of bbb.sip.app.ip and freeswitch.ip have the internal IP address.

bbb.sip.app.ip=<internal_ip>
bbb.sip.app.port=5070

freeswitch.ip=<internal_ip>
freeswitch.port=5060

Edit /etc/bigbluebutton/nginx/sip.nginx to connect to the external IP address.

If you have configured SSL, use port 7443:

location /ws {
        proxy_pass https://EXTERNAL_IP_ADDRESS:7443;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_read_timeout 6h;
        proxy_send_timeout 6h;
        client_body_timeout 6h;
        send_timeout 6h;
}

If enableListenOnly is set to true in /usr/share/meteor/bundle/programs/server/assets/app/config/settings.yml, as in

$ grep enableListenOnly /usr/share/meteor/bundle/programs/server/assets/app/config/settings.yml
    enableListenOnly: true

edit /usr/local/bigbluebutton/bbb-webrtc-sfu/config/default.yml change the value to ip to match the external IP address of the server, and the value of sip_ip to match the internal IP address of the server (where FreeSWITCH is listening to port 5066). For example, if the servers external IP address is 203.0.113.1 and the internal IP address is 172.30.1.145 then edit default.yml and change the values for ip and sip_ip as follows:

freeswitch:
    ip: 203.0.113.1
    sip_ip: 172.30.1.145
    port: 5066

After making the above changes, restart BigBlueButton.

$ bbb-conf --restart
