As a carrier that is STIR SHAKEN compliant, Call 48 certifies origination calls by attesting to the relationship with the caller, as well as their authority to use the DID phone number in question. The use of an attestation indicator represents the originating signer’s ability to vouch for the accuracy of the source of origin of the call.
Think of it like vouching for a friend when you them fix up. You know who they are, what they stand for, and their intentions. STIR SHAKEN attestation is like that. It’s a carrier’s way of saying we know who the provider is and vouch for them. Attestation comes in the form of either an A, B, or C.
Just because a caller receives an ‘A’ rating, it doesn’t necessarily correlate to their trustworthiness. Analytics will remain in place for call validation treatment to ensure that unwanted, scam, or illegal phone calls will still be labeled accordingly.
Let’s take a deeper look at what each rating means:[A] Full Attestation
SOURCE OF CALL + RIGHT TO USE CALLER ID INFORMATION
With Full Attestation, Call 48 has authenticated that the calling entity is authorized to use the number they’ve dialed from. [B] Partial Attestation
SOURCE OF CALL + DOES NOT HAVE THE RIGHT TO USE CALLER ID INFORMATION
Partial Attestation attests that Call 48 has authenticated the customer originating the call but cannot verify if the customer is supposed to be using the number dialed from. [C] Gateway Attestation
DOES NOT KNOW SOURCE OF CALL + DOES NOT HAVE RIGHT TO USE CALLER ID INFORMATION
With Gateway Attestation, Call 48 is able to authenticate a call’s origination but not its source. This type of call attestation is typically given to international calls.
