Is it banned? Isn't this part of how FreeConferenceCall works with IIRC dial in numbers on a little LEC somewhere in Iowa?

Yes, the rule became effective in 2019: https://www.fcc.gov/document/fcc-adopts-reforms-further-redu...

(FreeConferenceCall and similar companies lobbied heavily against this rule, but AT&T and Verizon were able to lobby it through.)
