Out of curiosity, what sort of business do you run? Is providing VoIP options out of the question?
I said what I said because I've disabled calls for people who are not on my contact list, whom rarely call me anyway, in favor of email and video chat like Hangouts. Most businesses can be contacted via email, and nearly all my correspondence with companies, when I was apply for jobs, was handled over email and Hangouts. It just seems to me like we already have plenty of viable options for ditching the outdated, low fidelity phone system, but maybe that's not for everyone. For individuals, however, I do still think disabling calls is worth a try just to see how much one really needs to be answering them.
