WI AG Kaul participated in Operation Robocall Roundup — 50+ AG coalition targeting VoIP providers facilitating illegal robocalls. Phase 1: 37 providers warned. Phase 2: expanded to Inteliquent, Bandwidth, Lumen, Peerless. Wisconsin's enforcement increasingly focuses on upstream infrastructure rather than individual callers — matching the national AG enforcement trend.

Wisconsin Act 243 (effective April 1, 2025) prohibits knowingly transmitting misleading or inaccurate caller ID with intent to defraud. New Wis. Stat. 100.523(2). Wisconsin had been relying primarily on federal anti-spoofing laws — this state-level tool gives the AG and DATCP independent authority to prosecute spoofing without federal involvement. Complements existing DATCP No Call Rules.

WI AG Kaul and DATCP participated in FTC's Operation Stop Scam Calls. Wisconsin's dual enforcement model (AG + DATCP) provides unique coverage — DATCP handles the No Call Rules (Wis. Admin. Code ch. ATCP 127) while the AG pursues larger enforcement actions. DATCP maintains Wisconsin's own Do Not Call list and enforces registration requirements for telemarketers operating in the state.

WI AG Kaul joined 49-state Avid Telecom lawsuit. Avid transmitted 24.5 billion calls including calls to Wisconsin numbers. Court denied Avid's dismissal motion in May 2024. Wisconsin enforces telemarketing through both the AG's office and DATCP (Dept. of Agriculture, Trade and Consumer Protection) — dual enforcement authority provides broader coverage than most states.
