Mumble

Free Public Mumble Server

For those who do not know already, I am also running a Mumble-Server.

Mumble is a free-open-source voicechat alternative, to other things like Teamspeak or Skype. It is a practical thing, the only disadvantage is, that it is server-based, so you need a server or use someone elses. So due to the lack of good free servers, I made one my own.
