They're using eight principles to tackle the problem through prevention and enforcement.
Phone companies will work to prevent illegal robocalls by:
- Implementing call-blocking technology at the network level at no cost to customers.
- Making available to customers additional, free, easy-to-use call blocking and labeling tools.
- Implementing technology to authenticate that callers are coming from a valid source.
- Monitoring their networks for robocall traffic.
Phone companies will assist attorneys general anti-robocall enforcement by:
- Knowing who their customers are so bad actors can be identified and investigated.
- Investigating and taking action against suspicious callers - including notifying law enforcement and state attorneys general.
- Working with law enforcement, including state attorneys general, to trace the origins of illegal robocalls.
- Requiring telephone companies with which they contract to cooperate in traceback identification.
