I have the SHM5 it says "hello" "goodbye" "phone connected" etc.. it would be useful and possibly the most important voice prompt you could have .. for it to say "call ended" or "phone call ended" so that when i am on my motorcycle with the wind and engine noise etc blasting in my ears i can clearly hear the call is ended without wondering if it really is and if the line may still be open which could potentially rack up a big bill or if i was muttering under my breath the other person could hear me... when the call is ended currently you get some bleeps.. erm well you cant clearly hear them when riding a motorcycle.. currently to ensure my call is ended i press the red phone button and it asks for a name or number to dial.. then i just cancel it.. that way i know the line is closed.
