This is a scam phone call of someone pretending to be the IRS.  They will try to scare you by telling you there is a lawsuit against you by the IRS for defrauding the government and that they are going to send the police if you do not send money right away.  They also operate under this phone number as well 305-501-2259.  If you get a phone call from them - report it to the TIGTA.
