title: BigBlueButton sound issue - can't join with audio neither listening (ICE error 1004)
body: <p>I am using BigBlueButton with canvas. I installed it using the script provided on their Github page, namely:</p>
  <pre><code>wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -w -a -v xenial-22 -s bbb.example.com -e info@example.com
  </code></pre>
  <p>The problem is whenever I create a conference and join it. I couldn't use the audio neither listening.</p>
  <p>When clicking on join with microphone, an error pops-up saying:</p>
  <pre><code>Failure on call (reason=ICE error) (error 1004)
  </code></pre>
  <p>And when I click on the Listen only, nothing happens.</p>
  <p>I consulted the logs but nothing useful, I suspected some sound errors due to host configuration but I am not able to get things clear. Maybe some of you could have an idea about which logs to consult.</p>
  <p>I suspect it is a problem related to FreeSWITCH, I followed a setup here about setting up FreeSWITCH with a firewall (even though I don't use a firewall but BBB config indicates that it considers a firewall) but nothing changed.</p>
  <p>Any suggestion would be appreciated.</p>
