There's no official word on this yet, but the inimitable Michael Arrington says that Google's up and purchased VoIP company Gizmo5 for "around $30 million in cash." You know, pocket change for the crew in Mountain View. The deal would presumably bring Gizmo's SIP-based VoIP talents to Google Voice
, taking it from quirky phone-management service to complete end-to-end calling solution, and instantly catapulting it into direct competition with Skype. Heavy stuff -- we'll see if Google or Gizmo5 confirms Mssr. Arrington's report sometime soon.
