The best way to prank all your friends and scare whoever you want. http://www.ospenterprises.com/phone/ ...enter the caller id name you want to show up, the called id number you want and a message that a robot will say to whoever picks up the phone! It's a demo version so you can only enter a certain number of characters but it's free...just enter the number you want to call with called ID included.
