I'd really like to set the Do Not Disturb (DND) function to block calls at night (with exceptions for calls from family). I set up a recurring schedule to go into DND mode between 9:30 pm to 7 am.
However, when I myself tried calling our land line from my cell yesterday (at 6 pm), I was given the "not accepting calls" message. I have experimented more with other time spans and once DND is set, it appears to block all calls regardless of what time it is and what schedule you have set.
Obviously, part of the reason to have the phone line is to be able to take calls, at least during part of the day.
