I second this request. I'm not crazy about # and *, as I can mimic those with a DTMF app from my cell. However, for those of us that seem to garner critizism for our enjoyment of rotary phones, it is a much desired feature.
Yes, forking out $50+ for a rotatone is possible, or $50+ for a dialgizmo, but that is not the point. If a hook flash can be programmed into the firmware, then there is little left to incorporate an entire 10 digit decadic protocol.
