All the Call Blocking Apps I could find seem to only have the ability to block all calls that the number isn't in your contacts list. I would assume (but maybe not) you can create an app that has access to not only read the phone number of the caller but if there is a matching caller ID name. nokia ringtones
If that were the case, I am perplexed why none of these apps have a feature to block all calls not in contact list *AND* Caller ID Name is blank or has no letters (in case the function returns the phone number) I know many apps keep a black list database but the problem is, many of the Robo Caller farms don't have all their numbers listed in the black list -- they are constantly changing their blocks of numbers they use -- but virtually none of them return a caller ID name. - you just see a phone number. And note, I am not talking about calls marked "Private", most apps block those.
Is this really not technically possible or are most of these call blocking app developers overlooking this useful feature?
