How to Set Up Simple Voice Chat on Your Server

Simple Voice Chat needs three things to work: the correct build installed server-side (matching your server's loader), a dedicated port opened in Additional Ports, and the same mod installed on every player's client. Miss any one of these and it'll "install" but stay silent.

Symptoms

• Mod/plugin shows installed but no audio in-game
• Console gives no errors, but players can't hear each other
• Works for you but not for friends (client mismatch)
• Mod fails to load entirely after a server type change (Vanilla → Forge, etc.)

Why this happens

Simple Voice Chat ships as separate builds for Fabric, Forge, and Paper. They are not interchangeable. Installing the Fabric jar on a Forge server (or vice versa) is one of the most common causes of it silently doing nothing. On top of that, the mod communicates over its own UDP port, which is not open by default. If that port isn't allocated in the panel and matched inside the mod's config file, voice data never reaches players even though the mod loaded fine.

Always match the mod/plugin version to your exact server loader (Fabric, Forge, or Paper) and your Minecraft version, a mismatch is the #1 reason voice chat "installs" but does nothing.

How to fix it

1. Confirm your server type first. Check Server Type in the sidebar: if you're on Paper, you'll use a plugin build; if Forge or Fabric, you'll use a mod build. If you need to change loader or version, see How to Change Your Minecraft Server Version.
2. Install Simple Voice Chat:

• Paper servers: use Plugin Installer and pick the version matching your server's Minecraft version.
• Forge/Fabric servers: use Mods Installer and pick the build matching your loader and version.

1. Go to Additional Ports and allocate a new port for voice chat.
2. Open Files and find the voice chat config (config/voicechat for mods, or the plugin's config file under plugins/ for Paper). Set the port value to match the port you just allocated in step 3.
3. Restart the server from the top bar so the plugin/mod picks up the new config and the port opens.
4. Install the matching Simple Voice Chat build on your own game client (same version and loader), then connect and test.
5. Have other players install the same client-side mod: voice chat won't work for anyone who skips this.

If the mod fails to load at all after installing, check the Console for a dependency or version error, mismatched loader versions are covered in Fix "Missing Dependency" and Mod Conflict Errors.

Still stuck?

If you've matched the loader version, allocated the port, and updated the config but voice still doesn't connect, open a support ticket with your server ID (shown on the Dashboard) so staff can check the port allocation and config directly.
