how do scam calls generate random phone numbers?

Question

I’ll get a call and sometimes no one even answers me when I pick up and then I will call it back and get the “this # has been disconnected ” response. How does that work?

It’s called phone number spoofing. You can make your calls appear like they are coming from a different number.

It’s also possible that they are coming from valid numbers that are not set up to receive incoming calls.
