MN AG Ellison launched Operation Robocall Roundup with 50+ AGs. Warning letters to 37 VoIP providers + 100 downstream providers. Companies failed to comply with FCC rules on traceback requests, Robocall Mitigation Database registration, or robocall reduction plans. Results: 19 companies stopped routing illegal calls, 13 removed from FCC database. Minnesota's consumer protection statutes give the AG independent enforcement authority beyond federal TCPA.

MN AG Ellison sent warning letter to iDentidad for routing spoofed calls that impersonated government offices (including the IL AG's office). Calls transmitted included IRS/SSA imposter scams, utilities scams, and financial scams. Warning: stop routing suspicious traffic or face legal action including damages, civil penalties, and injunctions. Pre-litigation warning letters are an enforcement tool — companies that ignore them face enhanced penalties as evidence of willfulness.

MN AG Ellison joined 49-state Avid Telecom lawsuit. At least 14,395 illegal calls transmitted to Minnesota numbers. While MN's call volume is lower than larger states, the AG office participates aggressively in multistate enforcement. Minnesota Stat. 325E.27 prohibits unsolicited calls using automatic dialing-announcing devices with penalties up to $25K per violation under consumer protection statutes.

MN AG Ellison joined multistate settlement against ACS/Directele sham charity operation. 1.3 billion deceptive robocalls targeting 67 million consumers nationwide, collecting $110M+ through false claims of supporting homeless veterans and children with autism. $110M judgment (suspended).
