What is SHAKEN/STIR?
SHAKEN/STIR is a new technology standard developed by industry experts to combat the rise in fraudulent robocalls and illegal phone number spoofing.
It's an acronym for Secure Handling of Asserted Information using toKENs (SHAKEN)/ Secure Telephony Identity Revisited (STIR).

How does SHAKEN/STIR work?
What do I need to do to prepare for implementation?
Telnyx will sign and attest to any outbound call that is not signed by our customer. Customers, however, should be aware of any applicable regulatory requirements to directly participate in the SHAKEN/STIR ecosystem and to sign their own calls as mandated by the Federal Communications Commission. Telnyx will pass SHAKEN signatures along that we receive in any outbound calls.
More recently, the FCC has moved up the deadline for small Service Providers to sign their own calls. Starting June 30, 2022, small service providers will be expected to sign their outbound calls with their own SHAKEN tokens. Telnyx will continue to sign calls we receive that are unsigned, but Telnyx is not responsible for your compliance with FCC regulations.
Full Attestation (A)
The provider knows the customer, they know the customer has a right to use the originating number, and they know that the call originated on their network.
Partial Attestation (B)
The provider knows the customer but the customer may be using another provider's phone number. The call is legitimate but the provider can’t fully attest because of missing information.
Gateway Attestation (C)
The provider can’t verify the customer or phone number and has no way of knowing whether the call is legitimate, however they attest to the call to mark that it originated on their network.

- ITG aims to be a neutral coordination platform for multiple service providers to trace and identify the source of illegal robocalls.
- We encourage all customers leveraging Telnyx for origination services to consider joining the ITG.
