A colleague could not get the audio working with a VOIP server Jitsi. However we got it to work once I opened up all the ports in the security group. The issue was that I had missed the fact that port 10000 needed to be open for video conferencing needs.
When debugging software, open up all ports at first to identify if it is a firewall issue at all.
