SHAKEN/STIR is a new industry framework that is mandated by the FCC to reduce the number of fraudulent and spam robocalls made over IP networks. With the implementation date of June 30th, 2021 past, many businesses are now wondering- what does SHAKEN/STIR mean for my business?
Before we dive in, let’s quickly recap the different attestation levels:
Full Attestation (A) is applied to a call when the provider knows the customer, knows they have a right to use the originating number, and knows that the call originated on their network. Numbers purchased on the Telnyx portal will receive an 'A Attestation'.
Partial Attestation (B) is given when the provider knows the customer, knows the call originated on their network, but the customer may be using another provider's phone number. The call is legitimate but the provider can’t give full attestation because some information is missing.
Gateway Attestation (C) is a given when the provider can’t verify the customer or the phone number and therefore has no way of knowing whether the call is legitimate. The originating provider will still attest to the call in order to mark that the call originated on their network.
If you think you need a little more context on attestaion, check out one of our previous posts that takes a deeper dive into the different levels.
Call Forwarding & Attestation
The current process for signing forwarded calls does not differentiate between signed and unsigned inbound calls. This means each forwarded call is signed with B attestation by Telnyx, regardless of whether the call has a toKEN from the originating service provider.
In the coming weeks, Telnyx will implement a new initiative which will alter this process depending on whether the call is already signed.
For inbound calls that contain an identity header, Telnyx will pass the identity header received for the incoming call and add a DIV passport to the call. In this case, the attestation will be determined by the originating service provider that originally signed the call.
For those inbound calls that are not signed, Telnyx will default to the original process where we will start a new call and assign it a B attestation. It will not have a DIV passport attached.
