Samsung Moment

Anyone tried to voicedial over bluetooth headset? I recently tried a different Android based phone and to my dismay, found that the phone did not respond to bluetooth voicedial. After some checking, I found out the issue was at the OS level with Android OS. Since the Moment uses voicedial by Nuance, I was wondering if this overcomes the shortcomings of the OS?
I love the Android OS but not being able to voicedial "handsfree" is a dealbreaker.
