Would be an easy problem to solve with a carrot instead of a stick. Just create a bonus for being the first person to respond to an out of hours group text, another bonus for being the person to respond to the most out of hours problems, and a year-end bonus for the whole team if no out of hours problem goes more than thirty minutes without a response from one of them. They'll organize the on call system themselves with no whining and you'll only spend money on actual problems since you're not paying anyone hourly to be on call. Everybody wins.
