[slide159] Yes, and now A could decide to actually set up the call. But because of this addition of messaging, we cannot only send text messages, we can send, yes, images too. So in my case, the usual message that I'll get from my wife is, you know, dinner, that means I'm getting hungry, it's time for you to be here for dinner, right, so hamburgers and french fries, baked potatoes, whatever, choose your menu. And people have built all kinds of services into SIP devices to support this now, because we can basically put up soft buttons, so we can give the users a menu of choice, so they get the message, they respond, violà off we go. Very cool services.
