Schedule for STIR/SHAKEN protocols?

From the FCC Website. 

spoom2 -- The last action listed on the FCC post you referenced was from a year ago. Since then, the amount of spoofed traffic that my phone sees has increased dramatically (and annoyingly). So either not much that is real has happened in the FCC's Caller ID Authentication program in the past year, or what has happened so far is ineffective (e.g., still full of holes). I'm curious as to where AT&T stands relative to this implementation. A search on the ATT website returns little of relevance, at least for landline customers. Do the experts have any projections?

The protocols were implemented by most carriers.  Most larger carriers are no longer accepting calls directly that they cannot certify the source of.  However, there are many smaller providers of one sort or another whose entire business relies on the shady sort of customer.  The FCC has just recently issued an order telling compliant carriers to no longer accept calls from one of these providers who have been found to be operating outside compliance with the FCC mandate.

If you read the article you'll see there's more to be implemented at the end of June 2023. You can also do your own searching to find out more information if you want. 

I was pleased to read about the FCC's action against One Eye. I'm looking forward to finding out that it will have some effect; but so far it is not noticeable. I got three Medicare-scam robocalls before 8 am this morning, and I'm sure there will be more during the day, as there have been every day for weeks.
