Do Not Disturb is passing all calls to voicemail
I've recently noticed a "new" behavior from my iPhone 5. I call it new because I hadn't noticed it before I installed 6.1.3, and it's still there after upgrading to 6.1.4. I'm noticing that other users have had similar results, and am curious if there's anyone who's having DnD work as it should. Here's the issue:
I've got Do Not Disturb configured to block all calls except my Favorites list after a specified time. Simple enough...I followed Apple's instructions to set it up, and it's not difficult. The phone is passing EVERY call, including those from my Favorites, to voicemail. Nothing gets through DnD...it's great if you really DON'T want to be bothered, but if there were an emergency you wouldn't hear anything at all or even see a notification until it was too late to answer (such as AFTER a voicemail was left).
My phone is simply a 64 Gb iPhone 5 running iOS 6.1.4. No jailbreak or unlock, so nothing out of the ordinary that should cause any problems or make diagnosis difficult.
I've tried changing the DnD time, with no luck. I can change the DnD block/pass list to allow everyone and it works, but that defeats the purpose (at least I know THAT part works). I've tried grouping my contacts and assigning a group other than Favorites for testing, but even that fails. I recently had to do a full restore on the phone to update to 6.1.4, so that's been done as well...it was the same on 6.1.3. I've reset network settings, no change there either. I haven't reseated the SIM, because I've never had a problem receiving calls normally, and disabling DnD returns the phone to normal (indicating that the phone IS actually getting the call, just mishandling it).
So, with that bit of background, does anyone have any clues what I'm missing or not trying that I should be? I'm at a loss on this one. Thanks in advance for any help!
