Caller Identity & Trust

When your team places a call, the receiving device makes a split-second decision about how to display it — or whether to ring at all. That decision is driven by carrier-level frameworks that authenticate where a call originated and control how your number and business name appear on screen.

The articles in this section explain the core systems behind call authentication and caller display. You’ll learn how STIR/SHAKEN validates that a call came from a legitimate source, how to register your business with analytics providers through Voice Integrity to improve how your numbers are treated, how Branded Calling can surface your company name and logo on mobile devices, and how CNAM controls the name shown on caller ID for landline calls.
