Hi,
Did you find a solution to this problem? I am having the same issue. The system won't recognize basic voice commands for the phone, such as "call work" (where "work" is one of my speed dials with that voice tag assigned to it). Also, it won't record certain voice tags because the system thinks it sounds too much like others that are already stored (the only tags I currently have assigned are "henry" "mom" and "work" and the system won't allow me to store "home"...not sure how that sounds anything like the ones already stored). This is very frustrating!
