[TriLUG] low bit rate audio for the internet

[Ralph Blach]

As stated before my son is oversees.  Is there a better audio call tool 
than skype that
That uses less of the cpu for audio processing and uses a lower bit rate?

At his base they do not have lower speed line and skype uses to much 
bandwidth.
This would have to be available on windows also.

Thanks
