Just got this call and did not answer. I tried calling back because my mom is visiting LA and the call never when through so looked up the number to be sure. Thanks 800 notes! I then googled this and the IRS has issued a warning for phone calls exactly like this - http://www.irs.gov/uac/Newsroom/Phone-Scams-C ... 5-Filing-Season

Told them it was a cell phone number and that they need to remove it from their calling lists IMMEDIATELY.
They hung up. After reading the comments here, they were smart to hang up!
No one here is calling you. Your callers are hard core Indian or Pakistani scammer/extortionists. They are beyond the reach of US law and ignore all US laws.
Invest in a call blocker; not a perfect solution, but it should help. Also, do not pick up on calls you do not recognize.
