This article is missing the single most important question about being on call: how often you get called.
It's one thing to be on call where you get called 2-3 times a year, because you're working on a quality system where bugs get fixed more often than they get introduced. Then the pay, if any, is mostly compensation for hurting your social life.
It's another to be on call where you get called 2-3 times a week, because the organisation has decided calling you is cheaper than fixing the underlying problems. In that case, the compensation better be worth messing up your sleep cycle and upsetting your partner.
