Phone companies can now outsource robocall blocking, but they are still on the hook

The US communications regulator has clarified how phone companies can use outside firms to help block robocalls. This means phone companies can hire specialists to digitally sign calls, but they remain legally responsible for verifying who is calling.

For years, phone companies have struggled to implement new rules designed to stop robocalls. These rules require them to digitally verify caller ID information. This change makes it easier for smaller phone companies to comply by letting them outsource the technical work, which could speed up the rollout of robocall protections across the entire phone network.
