Good suggestions on the stress reduction if you can't change the situation, which may unfortunately be the case. I am not technically advanced enough to know how to set my phone up to turn off calls etc, but maybe that would also work.
I'm also a teacher and our district prides itself on a lot of technology use. They usually issued email bulletins in these situations, rather than phone calls. Fortunately, my principal and our school technology coordinator are both much more reasonable and this problem just wouldn't arise- but I am very sympathetic.
I could never keep your schedule in a million years. It is just a guess, but I think that for most people, including other teachers, parents, etc, it would seem extreme to go to bed that early in the evening, and the resistance may be partly that they can't even imagine that 7:15 is an unreasonable time to call. So they may not think it is worth it accommodate you. However, if your district is like mine, parents' voices may be listened to when yours is not, so if you could get some parents to complain, maybe that would help....
I have also heard that expression "is this the hill you want to die on?" as well as this one: "Choose your battles".
Hope you are able to resolve this! Teaching is increasingly demanding as it is- none of us need any unnecessary stress added to the job.
