Scam calls are getting harder and harder to block because of this spoofing going on.
For instance, I received a call that showed it originated from my hometown (same area code as my number). Let it go to voicemail and it was some credit card scam. Called the number back while hiding my phone number and some sweet old lady answered and after I told her I had received a call from her, she said “Oh dear I’m sorry, I haven’t made any calls today.” I told her about the spoofing and that she may get more calls like mine and she said thanks for the heads up.
The scammer used a real, active cell phone number for the call. Criminal, but doable.
