Richard and Sal from the Howard Stern show use a Spoofcard to make prank phone calls. With the Spoofcard, they can call a radio station in Indiana from New York City and make it look like the call is coming from Indiana. With  the Spoofcard, they can change their voice, record the call and make it look like they are calling from another phone number. They don’t use a physical calling card. They use their computer to make prank phone calls. Howard loves Sal and Richard prank calls to Tradio. Hellllllllllloooooooooooo and welcome to Tradiooooooooooooo. lol

You can actually do free caller id spoofing. You can try the  for free three times on any phone. Then you have to pay. It’s worth the dollars.
