Keynote Declares VoIP Merely Audible

Normally we think of the audio of services like Skype to have great audio. I know when I use my Junction Networks OnSip service or VoIP connectivity from inPhonex the audio is fine, easily on par with the winner, CallVantage from AT&T which I also have. Even my tests with Earthlinks' TruVoice fared well, so I was somewhat surprised with the claims of the Keynote test.
