Don't think there is such a thing as wrong; its all in perspective.
Some folks need economical fxs's and some need fxo's (or a combo).
Regardless of which is needed, interfacing "the box" to asterisk
via ethernet (where feasible) has some interesting economics and
operational benefits, particularily if dsp/codec/canceller is in
the box.
