When it comes to robocalls, the FCC means business, though you could be forgiven for thinking otherwise as its various efforts over the last few years have crept rather than leapt forward.Global UC, a U.S.-based (but suspiciously generic) company that seems to provide automated and long-distance calling capabilities (as opposed to ordinary cell service), received a warning long ago that it would need to implement the anti-robocalling STIR/SHAKEN framework on its networks or be prepared to justify itself if it didn’t.When the FCC came calling in October with a final deadline, Global UC said it had STIR/SHAKEN in place but that part of its network would not be covered by it.Global UC provided no details, saying only “We are not needing this certification.” Oh … okay.The order issued today requires that “All intermediate providers and terminating voice service providers must cease accepting traffic from Global UC within two (2) business days of this Order.”In other words, Global UC is blacklisted — the first company to receive this punishment under the FCC’s robocall rules."
