PacketCollision has set up a Mumble server for us. If you want to voice chat with fellow FinalGear.com folks while gaming or even just to BS, this is the place to do it!
Address: forums.finalgear.com Port: 64738 which is the default Mumble port
Ha, found the "problem", at least for my side. I didn't notice that it installed 2 versions of mumble, the current one and the "downwards compatible" one, which I tried. But that being 1.1.x, it was too old for the server. 1.2.3 is working.
