The Federal Communications Commission has warned two additional voice service providers not to carry illegal robocall traffic, the latest move in its ongoing efforts to crack down on unwanted spam and scam calls.
The agency said that it sent warning letters to SIPphony of Arizona and Wyoming-based Vultik that they are apparently originating illegal robocall traffic, based on “numerous tracebacks” by USTelecom’s Industry Traceback Group combined with consumer flagging of robocalls to wireless devices without consent.
