The server does not have a Teamspeak. Getting one costs time and money and there is an alternative.
I setup a Discord Server – it’s free and has voice and text chat. Please give it a try.
If you really want Teamspeak, you can run a private Teamspeak server for you and your friends. It doesn’t take much resource nor bandwidth.
- Download it, run the server, make sure you open the default port of 9987 and you’re done.
