It is a great Open Source Tool for Videoconf in a Browser or via Smartphone App.

Although its written in Java, it's easy to setup in Debian Buster and it doesn't use soooo much Resources.

If you run a NAT'ED VS, you need to setup some additional Portforwardings and change some Settings in Jitsi Config:

mcedit /etc/jitsi/videobridge/sip-communicator.properties Add:

org.ice4j.ice.harvest.NAT_HARVESTER_LOCAL_ADDRESS=<Local.IP.Address>
org.ice4j.ice.harvest.NAT_HARVESTER_PUBLIC_ADDRESS=<Public.IP.Address>

Forward these Ports in your Firewall:

• TCP/80
• TCP/443
• or TCP/4443
• UDP/10000
