How does do not disturb work on an iPhone?

Looked like it would be possible to make it so the phone calls would go to voicemail but no such luck?

Actually it is supposed to silence calls, alerts and notifications. If it's working as it should, then calls that come in while it's turned on *should* go to voicemail. If they don't, maybe the caller just isn't leaving a message?

  • Iphone Do Not Disturb Not working? I downloaded the new IOS for my Iphone 4s and set the Do Not Disturb function up to come on at 9 pm and go off at 7:30 am. I see the moon symbol on the screen so it shows the DND is on, and I have set 3 numbers as favorites, but the favorites are still not ringing through. I missed a call the other night from a favorite, didn't ring, didn't light up the screen, nothing. Am I missing something?
