Stage a Simple Voice Chat client-required admission rule

Applies to: Simple Voice Chat; match the linked maintainer documentation to your installed platform and release.
Documentation checked .

Requiring the voice client changes Minecraft admission, not just audio. Test both permitted and rejected joins before enforcing the setting on players who may use a different launcher or a modpack without voice support.

Prepare the test

Identify the client mod, server implementation and allocated voice endpoint before changing audio settings. Keep Minecraft joining and voice transport as separate tests; success on one does not prove the other.

Make the change

  1. Prepare one client with the compatible Simple Voice Chat mod and a separate client without it. Confirm both can currently join, and keep panel console access available in case the new rule rejects an in-game administrator.
  2. Stop the server and preserve voicechat-server.properties. Review force_voice_chat and the documented millisecond unit for login_timeout before editing; do not confuse the admission timeout with a network or microphone timeout.
  3. Enable the rule for a controlled test window and restart normally. Join with the unmodified client and record the rejection timing and message, then join with the compatible client without granting operator status.
  4. Test the compatible client on an ordinary connection and after a fresh launch. Confirm it remains admitted and can establish voice; passing the mod-presence check alone does not prove that the separate UDP audio path works.

Check the result

The unmodified client should receive the intended rejection while the compatible client joins reliably. Check your published joining instructions so players know which client mod and Minecraft version they need before the rule becomes permanent.

If the test fails

Disable the requirement through the panel and restart if legitimate compatible clients are blocked. Investigate their handshake and version details before extending the timeout blindly or telling everyone to reinstall an unrelated modpack.

Allow a preparation period for existing players. A voice-required policy can exclude people who cannot install the mod, so make that community decision explicitly instead of enabling it as a connection troubleshooting shortcut.
