The IRS rarely makes phone calls. They correspond through the mail.
There has recently been an increase in a phone scam threatening people that the IRS will be at their doorstep in 45 minutes to take them to jail. The pranksters give a badge number and call themselves a Legal Officer. The phone number that has recently been reported to UGJ is 831-316-9795.
