Ventrilo 2.1.4 has passed away. And I think it was about time. So much trouble to get it to work in Windows 7. It was not worth it.
Mumble 1.2.3 has a new way of thinking in administration and the use of channels that ventrilo didn’t. The sound is very good and uses less bandwidth compare to ventrilo. And has allso a dynamic traficshaping.
I hope that you will enjoy the Mumble as new way to comunicate. /Moose
