STIR/SHAKEN is Shaking Up the Industry

Could Stir/Shaken be the latest James Bond-inspired beverage?  Not in the telephony world.  These FCC call handling protocols are serious business. This new authentication framework is designed to reduce fraudulent robocalls and illegal number spoofing.  In our industry where call traffic is our livelihood, Inventive Labs is ready to help your company understand and navigate these new calling protocols.

STIR – Secure Telephony Identity Revisited
SHAKEN – Secure Handling of Asserted information using toKENs



We are STI-GA and STI-PA Certified

Voice Elements powered by Inventive Labs is a certified Communications Service Provider authorized to sign outbound calls with an appropriate attestation level.

STIR defines how the protocol could be implemented, while SHAKEN documents how the protocol will be implemented.  Used together, the originating and terminating service providers work in tandem to deliver valid calls.

ATIS explains, “When you make a call, your phone carrier will use your identifying number to create a digital signature, or token, that will accompany the call as it is being completed. At the other end, the system verifies that nothing was tampered with, ensuring that the call came from someone with a legitimate right to use that number.”   [ATIS STI-GA, Governing Authority for STIR/SHAKEN, SHAKEN: Frequently Asked Questions]


STIR/SHAKEN: What You Need To Know


What Happens to Calls I Place?

Inventive Labs will assign call attestation to every Voice Elements outbound call and pass this to the carrier in the SIP Identity Header.  ATIS Standards determine how we must assign the attestation as described in this table:

Attestation Level Industry (ATIS) Standard How Inventive Labs Assigns Attestation
Full or “A” The service provider knows the customer and their right to use the phone number. You are an Inventive Labs Voice Elements customer and your outbound caller ID is a number in your Voice Elements account or you have documented with our team your right to use that caller ID.
Partial or “B” The service provider knows the customer, but not the source of the phone number. You are a Voice Elements customer using another provider’s phone number.
Gateway or “C” The service provider has originated the call onto the network but can’t authenticate the call source. We do not handle transient PSTN traffic. We currently do not assign this attestation level.


How Can My Calls Always Get an “A” Attestation?

To achieve this goal, here are some tips:

    • Provision your numbers through your Inventive Labs Voice Elements account.
    • Port your numbers to Inventive Labs.
    • Identify any caller IDs you use on outbound calls that are not phone numbers in your Inventive Labs account. Contact us to explain and document your right to use those numbers.
