Black Berry - Reach me anywhere Phone

The BlackBerry, which for many companies has become an extension of office e-mail, might also become an extension of the office phone system, thanks to Research In Motion introducing the BlackBerry Mobile Voice System.
Describing the new offering as "the seamless convergence of a BlackBerry smartphone with an office desk phone," RIM said MVS allows BlackBerry users to be authenticated to an enterprise telephone system, and to gain access to those functions right from the BlackBerry's menu.
With MVS, a user can give out what RIM calls a "Reach Me Anywhere" phone number that rings both the owner's office desk phone and the BlackBerry. The user's corporate caller ID is displayed from the BlackBerry as well as the office phone, and the smartphone can access such deskphone functions as transfer, extension dialing, and voicemail.
