Imagine you've just taken off on a business trip. You are ready to open up your laptop PC and get some serious work done for the next three hours. You recall that less than an hour ago when you were racing out of your office there were several important voice messages you didn't have time to listen to. You could make an expensive air-to-ground phone call to check your messages....or, if you were a Unified Messenger subscriber, you could have downloaded your unheard voice messages to your PC and you could listen to them now.
