Zoom Phone will show a checkmark icon to help users identify robocalls and spam calls. The checkmark icon appears if the carrier has determined that the calling party is authorized to use the calling number.

Where the icon appears

The checkmark icon appears in the call history, recording, voicemail, and SMS logs; and inbound call notifications (client, app) for these inbound call scenarios:

• Extension to extension Zoom Phone calls in the same account
• Call between Zoom Phone users from different accounts
• Incoming calls from the US public telephone network when the originating carrier has provided an A-level attestation per STIR/SHAKEN guidelines

STIR/SHAKEN

STIR/SHAKEN is an industry standard that requires carriers to digitally sign calls originating from their customers. SIR/SHAKEN helps users identify robocalls and spam calls by determining if the carrier has authenticated the calling party, and they are authorized to use the calling number.
