What's your caller attestation?
Carriers grade every call you place A, B, or C, then decide whether to ring, label it Spam Likely, or drop it. Most callers never see their own grade. Call our line from your number and find out in seconds, free.

See your attestation
We read what your carrier signed onto the call: your STIR/SHAKEN grade, your caller ID name, and your spam reputation.
What the A, B, C grade means
STIR/SHAKEN is the carrier framework that signs a cryptographic token onto every call, stating how sure the originating carrier is that the caller ID is real. That confidence is the attestation grade, and it directly drives whether your calls get answered.
Full attestation
The carrier knows you and confirms you own the number. Best delivery and answer rates.
Partial attestation
The carrier knows you but cannot confirm the number. More likely to be labeled.
Gateway attestation
The carrier cannot vouch for the call at all. Frequently flagged or blocked as spam.
One check is a snapshot. DummyLead is the camera.
Your attestation, CNAM, and spam reputation drift over time and differ across carriers. DummyLead plants seed numbers in your real call flow and grades spam and attestation on every inbound call, so you catch a downgrade the day it happens, not after answer rates crater.
