Multiple sources with knowledge of the deal are saying that Google have bought Gizmo5 for around $30 million in cash, and the deal will be announced shortly. Gizmo5 is a good fit with a number of Google products. Google Talk allows voice calls between users but has no PSTN link to allow incoming or outbound calls to real phones. Gizmo5 does this well already. And Google Voice is a great VoIP and phone identity service, but they’ve no endpoint for calls. Gizmo5, which already integrates with Google Voice, is a soft phone end point for Google phone users. In other words, you’ll be able to make and receive calls to your Google Voice phone number from your computer.
