210-418-5061 --- It is a scam!!!
These calls telling you that IRS is filing a lawsuit against you. They are trying to make you call back so they can scare you into providing them with personal info! The IRS released several warnings about this: http://www.irs.gov/uac/Newsroom/IRS-Reiterate ... -Telephone-Scam
I received a call saying this is your last call. IRS is filing a lawsuit against me and to call the number. So I called the number and it is a call from Magic Jack
