@jonathanmayer Any idea why the landline companies don't address this issue? Do they make money from spam calls? I signed up for the Nomo Robo service, that I believe won an FCC sponsored contest to provide a partial solution. And I think the landline providers actively faught against its use.

I imagine a significant number of POTS lines are used by robocall/scammer operations, if not directly through third party VOIP services. Make not qualms about it, ATT still treats POTS as it's bread and butter. They will do whatever it takes to keep that cashflow coming in.
