I have call blocking set to 'High' (everything but block all except contacts), and I have over 550 specifically blocked numbers. I block every call that doesn't have a recognized CID and doesn't leave a message. (and a few that do leave a message) All blocked calls get number disconnected message.
But I still average 3 - 4 spam calls per day. With my old land line I hardy got any - 2 or 3 a week.
Am I doing something wrong?
Is this normal with Ooma? Your experience better or worse?
