this better be good, page-45

I get your point, and it would be advantageous, but with due respect the corporates are heading away from mobile numbers. Many organisations only provide single numbers now, and this will increase. It is accessible across all devices, the corporate handset, PC, laptop and tablet. It enables the organisation to protect their IP (when a salesperson walks out the door customer can't cal them) and for staff that don't have corporate mobiles & BYOD, they can still be accessible (or not) without giving away a personal number. It also means that all calls are handled professionally in that they can be routed to others in the organisation after say 3 rings rather than creating a mass of personal voice mails.
