I just got a call on my house phone as well, although this person is now claiming to be the Department of Justice. When I asked to find out more he told me he would transfer me to Detective Jones, and put me on hold, the person came on the line and it sounded just like the person I was initially talking to. I told "Detective Jones" that and they hung up on me. I called right back and their phone went straight to their answering machine.
I checked online for the Department of Justice's number and told them someone called me, they directed me to their fraud services which advised me to report it to the FBI at this number: 1-800-225-5324
Then I Google'd the fraudulent number that called me (917-460-4589) just to see what would come up, and found these posts. Hope these responses help anyone else who is receiving these fraudulent calls!
