STIR/SHAKEN Verification

Customer retention and brand trust improve with STIR/SHAKEN confidence. Check what certificates were assigned to your business.

Are you STIR/SHAKEN Compliant?

The Federal Communications Commission (FCC) requires voice service providers to implement STIR/SHAKEN framework to impose call authentication technology on Voice over Internet Protocol (VoIP) calls and business communications in North America. We suggest a tool to help you easily verify if your DIDs meet STIR/SHAKEN requirements.

High protection

You can protect your phone numbers from call blocking, spoofing, and spam tagging and deliver an accurate and consistent call display to increase contact rates and engagement.

Meticulous verification

As more carriers start to roll out STIR SHAKEN authentication, phone numbers and call sources will be meticulously verified for attestation levels.

Improved reputation

Our IDT Express STIR/SHAKEN Verification tool can help you identify your attestation levels and assist you to build trust and confidence in your voice calls.
STIR is an acronym for the Secure Telephone Identity Revisited (STIR). SHAKEN is an acronym for Signature-based Handling of Asserted Information Using Tokens (SHAKEN).
Customer retention improves with STIR/SHAKEN confidence. The FCC STIR/SHAKEN mandate creates the USA standards that enable both CPaaS, UCaaS, and CCaaS providers & end-users to verify that a call is really from the number shown on the Caller ID. The goal is to reduce robocalls from spoofed numbers.

What are Attestation Levels?

In a STIR-SHAKEN call, the originating service provider attests via data in the SIP header to their relationship with the caller and the caller’s right to use the calling number. One part of the data is the Attestation level. There are three levels of attestation that can be applied to a call:

Attestation — Full

The voice service provider knows the end-user customer and their right to use the phone number.

Attestation — Partial

The voice service provider knows the end-user customer but not the source of the phone number.

Attestation — Gateway

The service provider has originated the call onto the network but cannot authenticate the call source e.g., international gateway.
Once a call has been given an Attestation level, that level may not be changed by another carrier.
