South Dakota Attorney General Marty Jackley has announced the launch of Phase 2 of the National Operation Robocall Roundup, a coordinated effort to stop illegal robocalls. As part of this phase, warning letters have been issued to four additional telecom companies, directing them to immediately halt the transmission of unlawful robocall traffic across their networks.
Attorney General Jackley is a member of the 51-state Attorneys General Anti-Robocall Litigation Task Force, created in 2022 to combat the nationwide robocall problem.
The four companies receiving letters in this latest round are Inteliquent, Bandwidth, Lumen, and Peerless. Each has been ordered to stop routing suspected illegal robocalls.
This action builds on progress made in August, when the task force sent warning letters to 37 smaller voice providers. That earlier effort led to:
- 13 companies removed from the FCC’s Robocall Mitigation Database, preventing any U.S. provider from accepting their call traffic.
- 19 companies eliminated from traceback results, signaling they had ceased routing suspected illegal robocalls.
- At least four providers terminating high-risk customer accounts identified as sources of illegal traffic.
