I didn't answer and caller left no message.

Everyone should call their Senators and request a law that if a business calls they cannot use a spoof to hide their telephone number and if they do it is a 25,000 fine. The business must have on the caller ID the correct name of their business. This will stop all these scam calls.

Except for the criminals that then spoof the numbers of legitimate businesses.  Perhaps you would like to name me just 1 law that has ever stopped anything?  Just 1, you can chose from all the laws of every country in this world, and can even use the Ten Commandments as well.  Shouldn't be too hard for you.  I am only asking for 1.
