True.
For a pure substance at a given pressure, the equilibrium temperature at which the solid and liquid coexist is the same whether you call it the melting point or the freezing point. (Apparent differences can arise in practice because of supercooling, superheating, or impurities, which are kinetic or mixture effects, not a change in the equilibrium temperature.)
