At least a strategy to ignore unknown international numbers has much less collateral damage if any. All emergencies from unknown numbers that I can thank of will be from local numbers. I personally answer all phone calls but I have very little of those spam calls (on average once a month perhaps?) And I have learned to just rudely stop the call without saying "sorry, I'm not interested".
