Google Voice Discovered Allowing Pure VoIP Calls

From the article "Google Voice users learned late Monday that the service now has a way of making purely Internet-based phone calls. Making a SIP call with a 'sip:' prefix, the Google Voice phone number and @sip.voice.google.com skips the conventional phone network entirely, saving users cellphone minutes. Disruptive Telephony tested it and found that a call worked 'great.'"

Not encrypted at all.

Plus Google records all your calls. I wouldn't trust Google for anything. I have no idea why people like Google.

I remember one time I accidentally created a SIP client. I was just trying to compute some fibonacci numbers.
