Hi folks, been away from the carpc scene for a while, now I'm back

new carpc, new motivations, new software, old questione (I searched a lot without a clear answer)
Just tried out cf 2.0 final, really great piece of software, it made big improvements.. geez even phone works perfectly

I was wondering before using it in real life, how do you deal with echo cancelation? any working fix? suggestions? it's the only think stopping me to apply CF 2.0
thanks all
