Whenever you dismiss a call it sends the caller directly to voicemail. That basically advertises to them, "Yes, I saw your call, and chose to not answer it!"
Is there a way you can set your dismissed calls to keep ringing in the background so the person doesn't know you're dismissing them and instead just thinks you missed the call?
