Who called from 4042362600

The company is IBM ISS

Incoming call from this number Sunday 6/27/2010:  answered call; caller did not speak.    Unlikely that IBM would act like that, or, that IBM would call my office (business) line for no reason on a Sunday.    Number may no longer be connected with IBM; may now be with some kind of boiler-room outfit or something like that.

I just had the exact same thing happen; they called my cell phone and wouldn't speak.

I also got a call from this number at 1am at work.  Caller left no message.

Received a call on 8/31/2010 @ 12:48 AM.  No message was left.  Area code 404 is Atlanta Georgia.
