| Setting | Value |
|---|---|
| RTC Server Address | 0.0.0.0 or [::] |
| RTC Server Port | Leave blank for 8443 default, or change to another available port |
| ICE Host Override | Your chat server's host name, e.g. mm.organisation.example, unless that may not resolve to your public IP address when queried locally on that server. The latter can occur if you have an entry in your hosts file that resolves to a loopback address, or split-horizon DNS, in which case you need to enter the IP address or a different (sub)domain that always resolves to it, e.g. calls-mm.organisation.example. |
| ICE Servers Configurations | Leave blank |
Allow/restrict incoming UDP connections to the RTC port in your firewall's rules,
and/or forward that port through any network device between your server and the Internet.
Disable then reenable the plugin, or restart the Mattermost service to get it to pick up new settings.
Lastly, check the port has a listener attached, e.g. ss -plnu.
