This could be one of MANY numbers for YMax Communications Corporation, althought the phone is answered by a message from Magic Jack... but this number was reported on ComplaintBoard.com as belonging to a YMax Communications scam artist.
I Googled YMax Communications, and they are the #1 worst source of SCAM complaints on the ComplaintsBoard.Com website.
According to many of the complaints posted, they lie about everything to get you to give them money (like saying that you've been named in a lawsuit, or claiming that they represent the IRS, or offering ‘Free Government Grant money’ to recently-arrived foreigners, etc).
One complainer said the people they spoke with at YMax had heavy Indian or Pakistani accents, so they might be based beyond the reach of American laws and have the phone calls transferred to them.
Based solely on my web research (and not on any personal experience beyond the first call I got from them), this is probably the worst telephone scamming operation I've ever learned about...
This is a Pakistan or India based IRS scam. Do not fall for it. The IRS does not initiate any legal action via phone.

As general background information, here are a few things you can do:
1) Report it to TIGTA under http://www.treasury.gov/tigta/contact_report_scam.shtml especially if you have become a victim (lost money, gave personal information etc.). You can also file a complaint with the Federal Trade Commission at ftc.gov/complaint (include “IRS Telephone Scam" in your complaint). This way you can also help the government establish specific fraud patterns.
2) Help kill their phone lines but not by calling them back directly (the number may be spoofed and repeat calls by you may - under exceptional circumstances- amount to harassment). The scammers use Voice over IP lines (e.g. magicJack (Ymax corporation)) to make it seem as if they are calling from the US. This is always against these companys' terms of service and can lead to immediate termination of their contract and blocking of their IP addresses for future attempts to register. Do a reverse look up of their telephone number (e.g. www.whitepages.com) to identify the Voice over IP provider and report it to the company and/or law enforcement (local police and/or state attorney general)
3) If you are really annoyed: call or write to your representative in Congress. As these scams happen all over the country maybe this will trigger a reaction and provide US law enforcement agencies with the political backing and the resources they need to work in India and Pakistan together with local authorities (it can happen, read: http://www.ndtv.com/article/india/ex-call-cen ... mmission-320427). A US task force has already been set up in Jamaica to nab scammers there (see http://www.ice.gov/doclib/news/library/reports/cornerstone/cornerstone7-1.pdf).
