This feature is very confusing to me. But I think I may understand it now. So, if you don't answer your phone or press anything on your phone, it'll just go to VM like normal. But, if you see the call you can send the call to live VM, and it intercepts the regular VM and "screens" the caller. They are prompted to speak and you will see what they say on the phone and can choose to answer or not. When it worked it was pretty cool. Just don't know how often I'd actually use it. This would have been a really great feature like 8 years ago lol
