I also got a call from this number with no message left.  I tried to call it back, & the voicemail box was full.  Hmmmmm...

ive too have been getting alot of annoying calls from this area, another one with same area code was 206-456-0661 both of which seem to be all of the sudden disconnected

I GOT THIS NUMBER CALLED TODAY, DONT KNOW WHO THEY ARE, BEWARE!!!!

same crap as yall!   gettn pretty tired of all these calls

Received a call yesterday on my government BB. My wife has recently received SPAM and robo-calls on her cell. I agree with those who do not pick up. These are likely robo-calls checking for live phone accounts. Once you pick up, it confirms the account is live and you risk becoming SPAM bait. The call may appear to be from a Stateside call center, but it more likely originates off shore.

I have a Verizon work phone in KC, MO and got a call from this number at 11:56 am cst 23-FEB.  Could be Verizon related since I don't give out this number.

I got the call on my cell phone no message.

I got the call too! The phone smelt of trouble. I was not even about to pick up.

I received a call, left no message.... Wow already 7 pages of responses for this number.  Looks like another surveyor is preparing by seeing how many actual people pick up within a 4 ring limit or another scam company is preparing for the same so they can start phishing calls to collect your personal information.
Just another reason to block / black list this number.
I use the App for my Android "Call Control" by EveryCall.US
I can blacklist these numbers and never have to worry about them again.

Just got a call, did not answer, no message . stlouis missouri

I answered my call and it immediately hung up. My guess is it's an automated machine going through numbers imputed by a computer. People think it's funny.

If you call and can manage to get on the dial tone line again (you got lucky, and got on an outgoing PBX node) dial 911 on it and scream "help someones trying to kill me" then hang up. Police will be dispatched to that numbers address. I called but wasn't lucky enough to get a dial tone. Just busy signals.  I'm going to try a few more times and do the aforementioned.  I bet they stop with the calls then.

called my phone did not leave a message, first time to get it

Received a couple calls from this number yesterday. Changed my voice mail greeting to a fax machine sound.  Hasn't called back since.
