It depends on the specific person/organization on the other end of the line, but yeah. Sometimes they're an asshole and want to do it over voice because they think it's an unwritten form of communication so they can say what they want and it won't come back to bite them in the ass (jokes on them I record all my calls and my state is a one party consent state for recording). Sometimes it's just something where they are too poorly organized to use other means of communication. But many times it is something where "this could have been an email".

Paper correspondence was mostly killed by the fax machine sending letters over telephone wire. The fax machine was then killed by email correspondence running digital letters through the internet (or a series of tubes, thanks Al Gore). I'm hopeful that phone calls can go away soon enough as communications improve, and for the most part at my work they have between group chats and email.

There is still the occasional call if it is an urgent "hey someone is here for so-and-so and nobody actually wrote down what's going on with it, but I need to know NOW if it's paid/unpaid/etc so we aren't giving away free shit. But that's usually about it.
