Install Truecaller. 99% chance you will see who it is, that it has been flagged as spam before and that it will not ring on your phone, ever again.
Does it still work with private numbers?
Mine only let's me know who it is if there is a number
...
As for private business numbers that are usually hidden, someone somewhere would have had a call from them and then added them as a contact. So that private number now pops up as Discovery life.
This is not possible.
I am assuming he means on truecaller.
Well technically there is a number...but it's just not displayed.
So I guess Truecaller could access that underlying number if the device allows it.
What I think happens is that Truecaller ads your contact list to the database. So you get a call from Discovery, flag it as spam and ad a contact name to the number. That is the "CLI" that then gets used and pops up on the next guy's phone.He's still wrong.
Truecaller just reads the incoming CLI and maps it to a name.
Private number = no CLI.

/sigh
If the next guy's phone is not sent a CLI from the network, it has no way of knowing WHAT number is calling. The CLI is not a name. It's the phone number. Number withheld = no number reaching the called phone.
I might have my terminology slightly wrong. Do me a favour. Install Truecaller and then tell me how "private numbers" (number withheld) and people that is not in your contact list, are displayed on your phone? I know it works, just not sure how.
