re: Majority of business related phone calls are a waste of time

I get it alot from directors and sr managers who get 1000 emails a day and don't necessarily read them all. If you need their attention on something, you have to reach out and get their attention. Likewise, when they need something, it's usually time sensitive and they want your direct attention instead of hoping you see their email.

And sometimes, the discussion isn't something either party wants to put in writing in an email.
