Rumors around the 'interwebs' suggest that Google may be working toward their own VoIP solution that will be built-in to Google Voice. The first sign of this possibility is that Google purchased Gizmo5, a popular VoIP calling service back in 2009, then recently shuttered it. Gizmo5 recently announced they will be shutting down their service in April. Typically, when a larger company acquires a smaller one for its products, then shuts it down, that is a sign it will very soon be integrating the shuttered project into its own product line.
The other rumor that lends credence to this speculation is that some people are able to place VoIP calls to a GV number after the following is added to the end of the number, “@sip.voice.google.com”. This seems to work only in rare and specific cases supposedly.
Google has been adding a ton of features to Google Voice recently, like incoming number portability, visual voicemail, and SMS functions, yet most of this is just educated conjecture at this point. Still, if the pieces do fit, and this turns out to be Google's plan all along, then very soon, Google will be an even larger player in the telecoms industry. This will result in a nice win-win scenario for Android consumers. What do you guys think? If you speculate further, its easy to envision VoIP over WiFI networks quickly spreading across the globe in 7-10 years... Does the idea of VoIP calls replacing all our regular phone calls appeal to you?
