Do Not Disturb is my favorite feature. Well thought out. You can turn it on manually, schedule it to turn on and off at certain times. (Needs to have a weekday / weekend setting) It has a setting to allow a group you specify to ring though or you can have it set to none.
The best item which can be on or off is the "Emergency ring though...named repeated calls. If the same number calls you twice within 3 minutes the second call rings through.
