You need 6 people to staff a 24/7 desk on a 6 week rota. That’s not on call, that’s actual work, assuming you don’t need to cover toilet and meal break or handle two fails with equal priority (when I used to work regular nights I’d have a pager when I went to the canteen)
You can do it with 5 but that leaves little room for covering illness and holidays, and you tend to end up paying overtime.
If you are getting frequent call outs out of hours, you need 24/7 coverage at a skill level high enough to reduce the total call outs to just a handful per year.
