Who owns this phone number?

Call came in on personal cell phone with Georgia prefix, didn't recognize it so didn't pick up. VM picked it up, message was cut off and robot voice left a number to call. I called from an untraceable line, man with a HEAVY HEAVY Indian accent answered the phone (extreme amount of background noise with a horde of people all talking int the background) speaking very slowly and deliberately "Hello this is Henry with the IRS Crime Investigation Unit, how can I help you?" ... uh yeah right ...
