The Federal Communications Commission’s (FCC) Enforcement Bureau (Bureau) has issued two new cease and desist letters in connection apparent transmission of illegal robocalls. See more here and here.

The Bureau issued the letters to Great Choice Telecom LLC and Telecom Carrier Access, Inc. d/b/a TCA Voip on February 10, 2022, indicating that the Bureau had determined that each recipient was “apparently transmitting illegal robocall traffic on behalf of one of more of its clients.” More specifically, “one or more investigations conducted by the Commission, in conjunction with the Traceback Consortium, revealed that [the carriers] apparently transmitted multiple illegal robocall campaigns from the sources listed” in an attachment to each letter.

The Bureau instructed the carriers to “investigate and, if necessary, cease transmitting such traffic immediately and take steps to prevent your network from continuing to be a source of apparently illegal robocalls.”

The letters further provide that “if after 48 hours of issuance of this letter [the carriers] continue to route or transmit harmful robocall traffic from the entities involved in these campaigns, downstream U.S.-based voice service providers may begin blocking all calls from [each carrier] after notifying the Commission of their decision and providing a brief summary of their basis for making such a determination.”

In addition, if each letter recipient “fails to take sufficient mitigating actions to prevent its network from continuing to be used to transmit illegal robocalls, then downstream U.S.-based providers may block calls following notice to the Commission. Failure to act within the deadlines authorizes U.S.-based voice service providers to block all call traffic transmitting from your network, permanently.”

As TCPAWorld reported, the Bureau has previously issued similar letters.
