put on federal do not call list to start

Got a call from this number on my cell. Nobody on the other end of the line when I answered.

got a call from a recording about my overdue IRS debt.  I don't have any IRS debt.

I got the same call for my overdue IRS debt.  I pay my taxes every year and am on the do not call list.
