I see how I can arrange/create a new group in icloud, but now how I can add that group to the DND, or exclude the contacts from it. Can you please further elaborate on what you mean? The DND choices on my phone are:
ALLOW CALLS FROM:
Everyone
No one
Favorite
GROUPS
All contacts
So how might this workaround be pulled off exactly?
I've only been skimming this thread, but it doesn't seem to me that you ever returned to this issue. Did you get get it figured out? If not, have you actually tried making sure the group got synced to your phone by viewing it in the Contacts app? When I view this menu in the DND settings I see every group that I've created.
Another option is the use the VIP group. It's primarily a feature of Mail, but it can be used with DND also. To do this open Mail and do the following:
1: Get to the Mailboxes list. Most people will leave Mail open either to the last email they read, or their inbox. In either case, just keep navigating back (using the arrow in the top left) until you can't anymore.
2: Now you'll be looking at all of your inboxes and folders. If you've only setup one email account you may just see the one inbox. Additionally, you'll see some filtered inboxes called "VIP" and "Flagged". Next to VIP you'll see a get info icon (looks like a lower case i inside a circle). Tap this.
3: This will take you to your VIP list, which is probably empty. Tap "Add VIP..."
4: Choose the contact for the person you want to add to your VIP list. Repeat until you've added everyone you want to.
5: Return to the DND call settings in Settings > Do Not Disturb > Allow Calls From.
6: Under Groups you should now see the VIP group. Select it.
Now only calls from members of the VIP group will ring when your phone is in DND. Do note that there will be one other effect of these steps. Emails from those who you add to VIP will have a star next to them in the Mail app. Further, if you look at the VIP inbox in Mail it will only contain emails from those you have designated as a VIP.
Ok, now that that's out of the way, what are you actually looking for? I'm not familiar with how Android phones handle "speed dial". Is it like the feature on regular phones where you store a phone number such that when you hold down 1 for a second or two the phone will just dial whatever that number is?
If that's the case, that seems pretty old fashioned to me. That requires that you actually remember that 1 will dial 555-1212 while 2 will dial 555-1234. I think Favorites is better than that because if I want to dial my wife's office number, I just see her name listed with the description of "work". I'm not left with the dilemma of trying to remember "Did I store her work number as 1, or is that her cell number?"
Honestly, since I have all my contacts setup in my phone I almost never use the keypad to dial a phone number anymore. If I do, it's usually because I'm calling an 800 number or something like that.
