Got call on my cell.  Did NOT recognize the number so I did not answer.  No message was left so I guess that it was NOT IMPORTANT.
FYI- you should NOT answer a suspected telemarketer/scammer call; even to "just mess with them" or to tell them to take your number off-their-list.  The only thing that is accomplished is that you VALIDATE your number to the computer-dialing-program so that it can now be bundled and SOLD to other telemarketers!

Called my cell phone, rang 4 or 5 times, hung up with no message

2 calls, no msgs, presumably spam

Dead  air, schmucks trolling for live numbers

Received a call from this number today. My caller ID, besides displaying the number, did not provide a caller name. I am not expecting any calls from central Los Angeles, including Hollywood so I would have to guess its just another of the dozens of telemarketers or trolls that continually call my number.
I'm sure glad "our" government and  law enforcement protects us tax-donkeys from these SOB's.
