Part One: Update on Centralized Registry & Registered Caller.

Presented by Chris Drake, CTO, iconectiv, and John Marinho, Vice President of Technology and Cybersecurity, CTIA.

SHAKEN creates a challenge for verifying (or attesting to the validity of) an enterprise because of the common practice of using multiple service providers.

Whether via a delegated certificate or a centralized registry, iconectiv and CTIA will explore:

  • The current state of voice verification
  • An overview of verification options (centralized or delegated certificates)
  • What the ecosystem needs to know
  • What to expect next
