Million Dollar Phone Idea

Accept call.
Reject call.
Reject call to voice mail AFTER appropriate amount of rings.

And there's the idea. Because some calls you can't or won't take right now,  but you don't want the caller to know this. So one more option which will make your phone stop ringing,  but the caller won't be sent to voice mail until the appropriate amount of rings,  preventing them from knowing that you hit reject.

In some ways it is polite. In some it is just handy.

I have no background in making things like this,  so I can't do anything with it. But I figured I'd toss it out there for someone who does know.

Have you ever wished your phone had this feature?
