Which port does Simple Voice Chat use?
Default: UDP 24454. Audio does not go through the Minecraft TCP port. Open that port in the firewall or hosting panel. Change it in voicechat-server.properties (port=).
Do I need to install it on the client and the server?
Yes. The server needs the mod or plugin; each player needs the mod on the client (Fabric, Forge or NeoForge). On Paper/Purpur the plugin stays on the server, but the client still needs the mod.
Can I use the same Minecraft port?
Not recommended. The game UDP port also serves query and can crash. Use a dedicated port (default 24454), different from query.port.
Voice chat does not connect. What should I check?
In most cases: UDP port not open or port= out of sync. Confirm UDP (not only TCP), restart after editing the config and use /voicechat test <player>.
Where is the config file?
Mods: config/voicechat/voicechat-server.properties. Plugins: plugins/voicechat/voicechat-server.properties. The port is not in server.properties.
Does it work with Velocity or BungeeCord?
Yes, with a specific proxy plugin. Proxy networks need extra UDP port setup between proxy and backends. See the official wiki.
