Attorney General Nessel Launches Operation Robocall Roundup, Issues Warning Letters to 37 Telecom Companies

*LANSING* – Today, Michigan Attorney General Dana Nessel launched Operation Robocall Roundup, a multistate effort by the Anti-Robocall Litigation Task Force to crack down on robocalls across the country. As part of the initiative, Attorney General Nessel and 50 bipartisan attorneys general are sending warning letters to 37 voice providers demanding that they act now to stop illegal robocalls being routed through their networks.   

“Operation Robocall Roundup will help ensure voice service providers do their part to stop illegal robocalls,” Nessel said. “I look forward to continuing to work with the Anti-Robocall Litigation Task Force to protect people from these persistent and intrusive calls.” 

These providers haven’t complied with Federal Communications Commission (FCC) rules about responding to government traceback requests, haven’t registered in the FCC’s Robocall Mitigation Databases, or haven’t filed a plan that describes how they will reduce illegal robocalls on their network. By disregarding these simple rules, these companies are allowing robocallers onto their phone networks and then passing their calls on to other downstream providers until they reach the phones of Michigan residents.   

The task force is also sending the letters to more than 100 downstream providers that accept call traffic from the 37 companies, so that they know they’re doing business with bad actors that are not willing to follow the rules that apply to everyone equally.   

The FCC is also taking a close look at several of these companies. It announced yesterday that it will be removing seven of these providers from the Robocall Mitigation Database, which means that other providers will no longer be allowed to accept and route any calls from their networks.    

The voice service providers receiving warning letters are:  


* Advantage Investors LLC  
* Alpha Stream
