Google Voice Discovered Allowing Pure VoIP Calls

Posted by CmdrTaco on from the who-needs-landlines dept.

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.'"
