Yes.  I received a call from this number yesterday.  There is another source you can find by using Google to search for this number that claims that it is a spam call for a home security system.

I didn't actually hear the call ring because they called one of my "extra" numbers, i.e., one that literally no one but me knows about and that I use only for special purposes (such as for sending outgoing faxes because it is not reliable for incoming faxes - I use another service for that and put the other number on my outgoing faxes, which is legal because I have both numbers and am not being deceptive).  Thus, any call to this extra number is either a wrong number (very rare) or a telemarketer picking numbers to dial randomly.

If anyone calls, there is actually a recording that plays immediately to the caller.  This recording identifies me as "ANonieMouse from 800notes.com!"  The recording warns the caller about scam calls (especially Nigerian scams) from the standpoint of the caller being a victim, not a scammer.  But it takes about 90 seconds to get through until the caller is allowed to leave a message in my junk call voice mailbox.  The caller hung up after 12 seconds, according to call detail records from the phone company, so I got no message from them.

Given my experience and what little else is being reported about this number so far, I wouldn't pick up a call from this number.  It would be interesting to see if anyone else has, or if someone has received a voice mail message from them.  I'd like to know what they are trying to sell.

By the way, my phone company's caller ID name service (as opposed to caller ID number service) did not identify the caller at all.  But that can mean very little, if anything at all.  Because of the way caller iD name is delivered to you, it is much less reliable than the Caller ID number, and even that can be spoofed and is often misleading.

I just received a call from this number.  I did not answer.

I RECEIVED A CALL FROM THE NUMBER BUT AS SOON AS I NOTICED THE 666 THERE WAS NO WAY I WAS GOING TO ANSWER!

Seems it is some sort of solicitation, I called back, pressed one for a cust svc agent, and got the option to leave a vmail, there is also an option to + your # to a do not call list, fyi, the comp never id's themselves though, bizarre...

If that is the only reason you wouldn't answer a phone number, then you are either a superstitious fool or a troll.  Numbers beginning with 314-666-8xxx are geographically assigned to Ladue, Mo.  From what I've read about that city, the people who live or who have recently lived there (including the late Stan Musial) are or were likely to be a lot less foolish and better educated than you are.
