Way back in November of 2009, Google bought Internet-based calling software company Gizmo5. The implications of the acquisition were pretty clear, and speculation about the possible integration of Gizmo5’s platform into the already thriving Google Voice system soon began. Yesterday, after over four months of radio silence from Google, the gang over at TechCrunch wrote: “We’ve confirmed that they [Google] have now built a Google Voice desktop application to make and receive calls.” While Google already has a desktop calling application — Google Talk allows users to place calls from their desktop — the functionality only extends to other users of the Google Talk network. Presumably, the new Google Voice Desktop application will allow Google Voice users to make and receive calls from their GV number to mobile and landline phones and not just other Google Voice desktop users. No time-frame was given by TechCrunch’s source. What do you think? Is Google going after Skype’s market share, or is this service something new and different?
