In reply to Josh.

You're right in saying Toni can hit Contralto notes, but even at her deepest, Toni still sounds like a woman while an androgynous voice is THE prerequisite for a Contralto. For example, you can't tell if Annie Lennox (from Eurhythmics) is man or woman. A lot of people mistake a really deep voiced woman for a contralto, even Toni said Brandy is one of the best contraltos out there, and neither are.
