Google has begun testing a Skype-like Google Voice desktop application. “The new app uses VoIP technology that was acquired by Google when it bought out Gizmo5 late last year, which competed with Skype by making P2P VoIP calls as well as making and receiving calls with POTS (normal landlines) and mobile phones. Gizmo5 fills some of the holes in the Google Voice product, particularly providing an endpoint for calls. Currently Google Voice users must assign their Google Voice phone number to an actual phone to make and receive calls. Google never commented on how they might use Gizmo5’s technology. But we’ve confirmed that they have now built a Google Voice desktop application to make and receive calls. From a user perspective, this will let Google Voice users take calls right from their desktop,” reports Techcrunch.
