STIR/SHAKEN for TDM networks - with Austin Spreadbury

In this episode I'm joined by Austin Spreadbury of Metaswitch (Microsoft) to discuss the latest updates in STIR/SHAKEN.
In our discussion, Austin Spreadbury (the Microsoft Program Manager responsible for Robocall solutions) and I take a look at the new ATIS specifications covering some options for using STIR/SHAKEN for calls passing over TDM networks. We also discuss how the STIR/SHAKEN roll-out has been going so far, and speculate about what the future holds.
