Actual number on CID is 171862991977. Name is "Not Available". Did not answer. Left no message. Number is not in service.

Same as greengene. Actual number is 171862991977. Name not available. Heard what sounded like many people in background as my recorded sent the "leave a message" statement. Then disconnected. Where do these guys keep coming from? Had a bogus IRS call just earlier on same day, from Vancouver.

Same as above - call from 171862991977  - name not available - I answered (lots of call center noise in the background) and it appears to be a scam - said they were calling from world wide web and  they monitor the "the internet" for all the major providers and they had found an error on my computer. I told them they hadn't and hung up but someone might fall for this...
