Allow sound for incoming calls to be turned off when on another call Merged

When on a call, it is very distracting when another call comes in. The new call rings in your ear while you are trying to speak with the current caller. If you do not ignore it, it just keeps ringing. I feel there needs to be a setting to turn that ringing off and only have a pop up come up on your screen to show you the new call coming in. That way you know knows calling but do not have the sound taking over the call you are currently on.
