Bumping this again -- this thing needs to be documented:
Kelsey, can you double check on the availability? I found this poking around the voice phone wiki pages:
" Live Screening is also available here - which will allow you to listen to voicemails as they are left and let you take the call mid-voicemail if you would like."

It's a checkbox on the comm portal "messages" page.
I just picked up a call and heard the words "SCREENED CALL" then the caller leaving a message; I was unable to find the right button to let me talk to the person who was on the line.
I've never before heard "SCREENED CALL" when picking up the phone but then we rarely answer the phone these days, it's so rarely anything other than a robocaller.
