TeamSpeak 3 remains a pillar of reliable, low-latency voice communication, especially for gaming, esports, and professional team coordination. While the client is straightforward, running a private TeamSpeak 3 server—particularly one exceeding the free 32-slot limit—requires managing a server license.

If you have an active NPL that has been in continuous use, it will automatically renew. However, TeamSpeak has confirmed that “Non-profit licenses are no longer given out. If you have a valid one it will be automatically renewed while in use. Once such an NPL expires it is gone for good”.

The new version will contain a default license with a later expiration date.
