I want to see who is at my door BEFORE I answer the phone.

I have the doorbell chime and when someone rings the doorbell I want to be able to see who's at the door BEFORE having to answer the phone. How do I do that?

There is no option to preview prior to answering the call. By default, the call is muted upon answering so you have control over whether or not to engage in voice communication.
