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:
“A” Attestation — Full
The voice service provider knows the end-user customer and their right to use the phone number.
“B” Attestation — Partial
The voice service provider knows the end-user customer but not the source of the phone number.
“C” 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.
