Received call from 657-220-1617 11-13-15 at 9.28A.M. stated Anaheim, CA. I was on the other line, don't know anyone in Anaheim, so I ignored the call and checked here....THANKS EVERYONE! They are now blocked!!! I get so tired of these calls and btw someone on this site recommended the Panasonic phone system...I have one and the call block feature is fantastic but the 1st handset died within 4 months and the others are acting weird now (Phone is about 1 1/2 yrs old now) so I will be phone shopping again next year....Just thought I'd pass along my not so fun experience with the Panasonic product! I,m weird...I expect if I pay a little over $100 for something it will at least last a few years. My last phone system lasted 5 years also a Panasonic. Next phone I get I guess I'll be shopping for another brand but since we no longer manufacture much in our own country I guess it's just like hoping someone knew what they were doing when they assembled the product you purchased!

Just called my cell.  Did not answer.  Blocked it.  Also blocked 657-220-1612 a while ago.  Must be the same outfit.

Called my cell!  Recorded message.  Said from customer service.  Then asked "can you hear me ok?"  I hung up.

Called my cell.  I answered and it said "don't hang up" which I immediate did.  Blocked.

They called and hung up after I answered.
Don't forget that spammers can have the number they call from appear to be from anywhere, even your doctor's office or bank.  So don't put too much stock in the phone number that appears on your caller ID.
