Google Voice would soon be part of Gmail as a VoIP service
Google Voice currently works only with telephone and mobile devices.
Google is however said to be working on a web based version that could function right within the Gmail platform as a VoIP based service.
The need to use a mobile device would be removed and Google would get another way of generating revenues.
It is not known how soon this service would be released for public usage. Google acquired Gizmo5 recently whose technology is likely to be used here.
