Source note · STIR SHAKEN attestation framework
Webex Calling marks an on-net call between Webex Calling users and an on-net call from a Unified Communications Manager user to a Webex Calling user as a verified user with an icon, classifying the Unified CM case by whether the caller identity matches the configured enterprise dial plan, and Cisco states that a call from a Webex Calling user to an on-premises Unified CM user carries no indication on the Unified CM client.
