US Anti-Robocall Litigation Task Force
It is unfortunate that the cellular companies have allowed their core product (voice calls) to be so devalued that they need to be forced to solve this problem instead of just doing it naturally.The carriers are clearly customer-hostile, as this is really a very solvable problem.  Instead, we now are moving to alternate mechanisms to manage audio calls (eg: Signal, Whatsapp, Facebook, etc.).  My wide-open Verizon cell-phone number is my least preferred method of contact by far, due to the fact that I cannot trust that unknown numbers are high-value incoming calls.
