This was mostly my experience. Once I was very Sr and reporting to the VP my solution was people could get in touch via the VP, his admin or my admin. Worked well (there were some things I really did need to be called for).

But not a general solution. But with a good manager can work more broadly. And I did see a couple managers do something similar for their teams, making it clear that if you need emergency attention contact the oncall, if for some reason that won’t do call the manager. This friction alone deals with most issues.
