Call blocking with spoken message?
I found one that does just this last week. Check out http://www.youmail.com. It's an app you download, but can manage it from their website. You can record different greetings for different people; family, business and the main reason I got it.... the number has been disconnected for people I REALLY don't want to talk to! I also have a msg just for Blocked Called IDs, telling them I dont accept them and to unblock their number. And...it's FREE :)
