Your version of "on call" is not congruent with ours or most of the world. When a doctor or DBA is "on call", they have to get up, fix something, and spend hours if not days doing it. We simply enforce communication. If you want to call that "on call" then your decision, and we disagree with that definition. To answer you question, yes, if you're responsible (in our subjective definition of what constitutes responsibility), you will answer within around 10 hours. In practically all communication you can reply "I got this I'll answer you later." or something similar to show responsiveness. The word responsibility stems from "response ability" and we believe that everyone should be... responsible. That's in our DNA.
