No one on line. Autodialer sounds. Other sites list as scammer. Blocked

An unwanted call from this Morro Bay invalid (spoofed) number arrived today.  When the call rolled to voice mail, the caller left no message, just dead space.  This is a favorite ploy of robocallers (unlawful telemarketers) who use spoofed numbers to cover their traks while trolling the phone lines seeking gullible schmucks to victimize.  Since I neither know nor do business with anyone in Morro Bay (especially anyone with a spoofed number), I conclude this was an attempted unlawful contact.

If you have been contact from this invalid (spoofed) number, please report your experience on this page.  Thank you.

I receive two or three calls from 805 area code.  I don't answer, but it is still annoying.

This number is dialing phone number automatically.

This person has been calling me every day for months, and I keep blocking the number on my iphone, but.  Then they continue calling the very next day and the last four digits of the phone number keep changing every day so every day of my life I have to go in and block their number.  The first six digits of their phone number always stay the same   Can you please help me ?
