Who called from 4029985021

Got this call on 6 of my lines tonight. I work for a call centre. As soon as it said the greeting, I'm sorry,  wrong number.

I received at least 3 calls from this number before I finally answered it. my caller ID said "Omaha, NE" and I'm a lawyer in NY so i don't answer telemarketing calls and that's what I assumed it was. but when he persistently called back and didn't leave a voice mail, I answered. I heard him saying "hello? hello? I'm sorry I think I have the wrong number." before I even spoke. Do you think he is targeting law firms??

This number called our business today (Saturday) at 1930 hours so long after we were closed.  I let it go to the answering machine but, naturally, no message was left.  Our business is not a law firm so, no, Judy Lawyer's Office, it's obviously not targeting law firms.  I have no idea what this scam is about.

I answer the calls with my name and say hello.  This guy interrupts me and says I have the wrong number and hangs up.

What is the malfunction here?  Clearly this person has too much time on their hands!

Same thing...as soon as I answered the phone, some guy is saying hello, hello...I must have the wrong number.
