Fortunately, my outgoing message is just rude enough to alert the caller's attention...It begins with a brief but unmistakable flatulence, then proceeds to warn off any 'sales pitch, religious or political hack, scummers and poll takers because we just aren't interested'. They usually make it just past the 'toot', and I get these 5-10 times a day...the scum scammers, not the frijole explosions.
I traced the phone number with spydialer.com, and it shows the calls are coming from somewhere on the corner of Pacific Coast Highway (also known as Bayshore Drive) and Dover Drive, in Newport Beach, California. On one side of Dover Drive is some businesses, on the other is Bayshore Apartments. Across the PCH is more businesses on one side of Dover Drive, and construction on the other. Three out of four might be a base for phone spammers. But good luck pinpointing exactly where they might be.
However, I also got calls fro 661-306-0083 as well. (See the post from Web User below.) That number traces to 43775 Lake Hughes Drive, Lake Hughes, California. Same company, same routine, MED CLINIC, etc. And they call at 7:00 AM, which really irks me, so if you can sue these clowns... There's somewhere to start.
