Ooma Telo HD2 Handset - meaning of icon on screen?

Hi, I couldn’t find any documentation on how to interpret my new Telo HD2 screen. I am seeing an icon in the upper right hand section with a phone handset and a red “X” next to it. What does this indicate?

Thank you in advance for any and all insight!

That means missed call. You can see who from by pressing on the right side of the center button (to view call logs).
