[ThisIsAWhatWhat]

What a crock. You can silence unknown numbers. Not to mention that nobody said you'd be forced to use this feature.

If an emergency happens with my parents, they're going to CALL ME. And the fact that I won't know about it if I happen to be in the shower or down the hall doing laundry or working outside for a few minutes is absurd and stupid.

Unbelievable that anyone would argue against this obvious OPTIONAL function, which has been present on telephonic devices for decades. Apple's handheld Unix computer/phone is the first I've had without it... and the one with the least excuse.
