should take specific action now that the labeling issue has been raised in the Notice of Inquiry that was adopted at the May 18 Open Meeting.” The STIR/SHAKEN mandate was a good first step, said Pasquale, but additional steps are needed to make it work as intended. “The FCC should amend STIR/SHAKEN to include end-to-end customer name (or rich call data when ready) verification and authentication along with phone number.” Unified Office recommends these steps be taken: • The originating service provider acquires digital certificates from a third party such as Neustar annually. The originating service provider attests and signs the number and the customer’s name. The customer’s name should be preserved and not re-labeled by any third party. The terminating carrier should prefix the caller’s name with an indicator that it’s possible spam rather than rewrite the caller’s name. The terminating carrier can run its analytics to determine whether the call is possible spam and, if so, notifies the originating service provider that this has occurred. This helps the originating service provider determine whether it is a spam call and, if so, address it so that it doesn’t occur again. • A feedback loop needs to be established in all cases (chain of custody). The SIP Forum has proposed a similar solution. • Originating carriers should undertake efforts to “know their customer” to avoid perpetuating fraudulent callers. The originating service provider should use an acceptable use policy for naming the caller ID and develop this in conjunction with the customer. Unrelated events? Some industry experts, on the other hand, are willing to give STIR/ SHAKEN more time. TransNexus founder and CEO Jim Dalton, for example, said the disappearance of caller ID and implementation of the FCC STIR/SHAKEN mandate are unrelated. “They are different events that just happen to be occurring at the same time. STIR/SHAKEN is a technology that improves the chance that the called party will receive a caller ID,” Dalton said. “Caller ID is disappearing because call termination service providers use robocall analytics to identify robocalls. These analytics are useful for limiting nuisance calls, but they also have a high false positive rate. “When a legitimate call is incorrectly identified as a robocall, the caller ID is replaced with a label such 65 SEPTEMBER - OCTOBER 2023 | CHANNELVISION
