Robo-dialer, trying to sell unsuspecting people on SEO, website creation and business listings. I made up a whole story, and pretended to be very interested. Made up a fake business on the fly, fake name, etc. Then I gave them an internal phone number for the local Orange County Police Department.
Received a call from 385-213-1075, no CallerID info. This call was blocked while still ringing by my call blocker device. The 385 area code had previously been entered on my block list after receiving a call from another number, same area code.
