anybody here have knowledge on NCID (network caller ID protocol) or any other legit caller ID systems programs or apps?

I have been in search of a legit caller ID option for my android phone and I can’t seem to find much info out there. Personally, I like to know who is on the other end of a phone number trying to contact me; especially catching spam callers. I tried the true caller route (I know, its not self hosted) and its good at what it...
