There's a way to clear the screen from showing that there is a New Voicemail waiting (even when there isn't), but you have to clear the screen after after every missed call, and with each handset (I added an extra one to get three handsets total).

very pleased with the well lit handets and screen on the base.

Then I saw the A T and T CL83207 which had all the items I was looking for including a number pad on the base, a large screen, call block, and answering the system

Very bright numbers, clear & bright name screens.
