If they've already moved on, it's likely pulled off your line as soon as they hang up anyways.
I got in from running sound at church one evening and a buddy came over... video games and whiskey were going to happen. I poured a glass, sat it on the table, and went about getting stuff done around the house before I sat down.
Finally, I sat down, picked up the glass to take a first sip... and ring ring comes the green slip call for a "as soon as you can" GS. I was a couple seconds away from losing a couple grand with that glass of whiskey! I tasked my friend to figure out how to get it back in the bottle while I ironed my uniform.
