STIR/SHAKEN

When using DIDWW for outbound call termination, no additional configuration is required from the customer.

  • Calls using DIDWW numbers as the Caller ID will receive the highest A-level attestation.

  • Calls using third-party numbers as the Caller ID will receive a B-level attestation.

For the latest updates on STIR/SHAKEN guidelines and DIDWW’s implementation, please refer to our news releases, as our options will continue to evolve with regulatory changes.
