The FCC's proposed Know-Your-Upstream-Provider (KYUP) rules have become a flashpoint, with state attorneys general on one side and the telecommunications industry on the other. The rules would require providers to verify the origins of call traffic, a measure aimed at reducing illegal calls. State AGs are pushing for the requirements, while industry representatives are resisting them.

A coalition of consumer groups has backed the AGs, arguing that rules like KYUP are "more vital than ever" to combat fraud. They point out that many providers profit from illegal call traffic, either by directly originating calls for fraudsters or by indirectly accepting such traffic from downstream sources. The clash highlights the ongoing tension between stronger oversight and industry concerns about compliance burdens.
