because eventually you wouldn't bother to press the button to tell the phone you are sleeping, which rendered this feature useless. And, it would be technologically very hard for the phone to know whether you are sleeping. I don't think you would have much problem securing a tenured chair professor at MIT if you can solve this problem.

your case is before pick up while LZ's case requires voice channel be established first to give caller the prompt, the call between caller and callee is already connected at this point (without network side support), not sure whether system allows an app to intercept the call at this point and then do different things based on DTMF input from the caller.
it's the ringer volume, not conversation volume. it would be useful to OP if some one can write an app to allow certain callers ringer volume to automatically increase.

I know Dialogic or NMS cards can do that, but that is for computer based systems.
