In America, not every school is staffed to the point where they can have someone sit on phones all day. Most schools around me are working on shoestring budgets, and I’m in a fairly cosmopolitan area of California. It’s even worse if you’re in a rural area because there’s no incentive to get good teachers there through pay rates or bonuses or anything like that. God help your kids if you’re in a red state. They are giving emergency teaching credentials to anyone with a pulse.
