Every eligible call signed at A-attestation. No exceptions. No upsell.
Your STIR/SHAKEN attestation level directly controls whether downstream carriers display your call as "Verified" or flag it as "Spam Likely." We don't compromise on it.
Not all attestation is equal.
Calls get signed at one of three levels. Only A-level reliably passes through the downstream filters that decide whether your call shows up as 'Verified'.
Full attestation
VICICarrier defaultThe originating carrier knows the caller AND knows the caller is authorized to use the calling number.
Partial attestation
Not what we sendThe originating carrier knows the caller but cannot verify they own the calling number.
Gateway attestation
Not what we sendThe call enters the network from a gateway (often international). The carrier has no visibility into the source.
Attestation level drives answer rate.
Downstream carriers weight STIR/SHAKEN verification heavily in their spam scoring. B- and C-level calls get flagged — a lot. Your answer rate is not separate from your attestation level.
A-level default
Every eligible call signed at A-attestation with no extra fee or configuration.
Your own cert optional
We can sign with our cert (default) or with your own STI-CA certificate if you have one.
CNAM + spam monitoring
Spam-flag monitoring across major US carriers. Portal shows your reputation over time.
Audit your current attestation.
Send us a sample CDR with SIP-identity headers. We'll read the attestation level your current carrier is signing at and tell you exactly what you'd get on our network. If they won't share the headers, that already tells you something.
