Verizon outlines their plans to stop robocalls

On May 3, representatives from Verizon met with members of the Federal Communications Commission (FCC) to share Verizon’s plans to combat robocalls. On May 7, Verizon representatives followed up on this meeting with an ex parte letter to the FCC outlining the discussion, including Verizon’s plans and expected timeline to implement Secure Telephone Identity using the STIR/SHAKEN framework.


  • Verizon representatives said that Verizon is “committed to deploying the STIR/SHAKEN authentication standard in our networks.”
  • They expect to achieve initial operational capability later this year, with the bulk of production anticipated for 2019.
  • Verizon reps explained the importance of moving swiftly to have a certificate governance regime in place prior to widespread cross-carrier passing on call authentication tokens.
  • Consistent with the recent NANC report, Verizon supports a hybrid governance model for the deployment of STIR/SHAKEN where the Commission endorses a flexible, industry-administered framework.

TransNexus view

This report represents another sign of industry progress toward stopping robocalls using the STIR/SHAKEN framework. STIR is a standard for authentication and verification of secure caller ID developed by the IETF (Internet Engineering Task Force). SHAKEN is a framework to implement STIR developed by ATIS (Alliance for Telecommunications Industry Solutions) and the SIP Forum.

We have already updated our NexOSS and ClearIP software with STIR/SHAKEN functionality. We can help service providers get ready for STIR/SHAKEN by providing the following:

  • Advisory and training services
  • Test plans
  • Assistance with configuring your Session Border Controllers for testing
  • Help with interop testing with the ATIS industry test bed and other carriers who have implemented STIR/SHAKEN
  • Implementation of our production-ready solutions

If you would like to begin laying the groundwork for STIR/SHAKEN, we’re ready to help. Contact us today for more information.
