Autoreject all except in contacts?

[Steve_Karl]

Hi there, ( G900A )
Is there a way to set autoreject to reject all calls except for numbers in my contacts?

Thank you!

You can block anonymous callers from phone... Settings....

Thanks Tim ... yes anonymous works but is only for incoming calls that have no CID.
I want to block all numbers that aren't in my contacts.
