Is an unseen character in phone call (V.O.) or (O.S.)? I don’t understand if it’s considered a voice over or an offscreen

  • O.S. What do you not understand?

    No, they're not. Did you do research? Try searching for diegesis.

A character that is off screen speaks from off screen.

Voice over refers to a n̲a̲r̲r̲a̲t̲o̲r̲ who narrates the story (e.g. in a documentary, where the narrator never appears in the film).
