Standups to me are just a way to ensure everyone is awake. And able to answer a simple question and make a sentence. I don’t exactly care about the contents, except from time to time when it makes us notice that a colleague is on a wrong track.
They're also one of my easiest ways to include remote workers- they always go first. (the phone is part of the circle)
I understand the benefit of standing together, but not if you're going to add an exception for someone talking on a phone from anywhere in the world. Physical alignment is a great metaphor for team alignment, and therefore physical absence shows me someone cares more about sitting on their porch with their dog than being part of the team at work.
