It's never bothered me. I mean, my speaking voice isn't any quieter than the DTMF tones that the Blackberry produces so I don't see what the fuss over "discreetness" is... Actually, the tones are really low on my 8700c. I guess I also mostly dial from my address book. In any case, I guess this should be an option to disable.
Have any of you bothered to email
