Got a call from this number at the office where I work.  At first when I answered I could hear someone saying "hello?  hello?" in the background, but as soon as I said that it was a law office they'd called, they hung up very abruptly.  Called the number back and got a voicemail for a "Jim" that sounded to me like a fake accent.  Not sure what these folks are up to, but I'm guessing it's some kind of scam.

Got a call from this number a few days ago, as soon as I picked up a man said 'Hello?'. I was at work so I immediately starting greeting the customer, but afterwards he just said, 'Oh, I'm sorry. I think I have the wrong number.' and hung up. Didn't think anything of it until it happened AGAIN today with the exact same man's voice. Something very fishy indeed.

Rcvd call from this number at 6:30 PM after business hours on my work phone.  No message.
Voicemail states "Jim" and Caller ID indicates "Omaha" according to other websites.
Appears to be with Qwest Corporation.

Same thing here- called my business, when i pick up- he is mid "hello" and then just hangs up abruptly...

Twice today, same thing.  He was saying "hello" as I raised the phone to my ear, and then he said "I'm sorry, wrong number." Annoying!
