I'm not sure if spoofed numbers are legal anymore, but there used to be a calling card called SPOOF CARD and you could change the caller id to anything you wanted when you called someone. I used to get customers that owed me money and wouldn't answer my calls to pick up if I put in a local area code or even put their own phone number in. I'm sure we could get dingleberry to answer if we didn't call from blocked numbers and could call from a number he recognized.
