Anyone know of a call blocker app that blocks all calls that are either not in the contacts list OR the Caller ID is just the phone number, or blocked/"Private Number". It seems most of the apps I've tried so far have this feature except if the option to block calls with no Caller ID don't block calls where the caller ID is just a phone number and not a name. An unrecognized phone number is just as bad as no Caller ID at all in my mind.
