The problem with Do Not Disturb mode is that it blocks all notifications, too, right? I've turned off every type of notification except the ones I want (just Google Hangouts, since I use it for work). So, I can choose to either have a phone that rings (which I never want to happen for anyone I don't know) or Hangouts that doesn't. I will have to look into third-party apps. I never really considered it, as I use Google Voice and want to keep using it, and didn't really think about it maybe being possible to use Voice plus something else that deals with calls...it seems like Voice is already too intrusive to inject more stuff in there (my calls are already delayed by as much as a couple of seconds coming in and out because of Voice; seems like more would just guarantee that I can't answer legit calls before it goes to voicemail). But, I do need to sort it out. Recently I've been getting multiple calls a day and have resorted to leaving my ringer off completely. My mom worries, though, if I don't answer for a while.
