Google’s Enterprise President Dave Girouard explained in an interview with eWeek that Google has been building on its business app suite and will launch an enterprise version of Google Voice later this year–a combination of applications that may prove disruptive to the Unified Communications (UC) market. With Google’s cloud based applications highly collaborative already, and with the combination of Google Voice, Talk, and Gizmo5, Google has the makings of a unified communications app bundle that could be as cheap, easy to use and ubiquitous as its search engine and email offerings.

Later this year, Girouard said, Google would release a version of Google Voice for businesses, but he did not go into specifics about a timeline. At the moment, Google Voice has 1.4 million users routing calls through the service. Currently, Google Apps has 2 million business customers paying only $50 per user a year to use the software suite. As Google continues to develop and launch its VoIP play, they will have a built-in business audience to offer their services.
