Every call signed A-level.
We own the OCN. We sign identity headers on every eligible US/Canada call. No gateway attestation dressed up as something else.
At no extra cost. Every time.
Most providers quietly sign at B- or C-level to cut costs. Your calls get flagged as spam. We don't play that game.
Every eligible call signed at full attestation. The OCN is ours. The customer is verified. The destination matches.
Caller identity verified but origination ownership not. Rings through — but scored lower by analytics engines at the terminating carrier.
No identity verification. The call is simply gateway-attested. Most carriers do this quietly to cut cost.
If your current carrier won't show you their SIP-identity headers, that already tells you what level they're signing at.
Paste a SIP Identity header. See the truth.

Every originating provider must recertify its Robocall Mitigation Plan by March 31, 2026.
The FCC's 2024 Second Report and Order requires every entry in the Robocall Mitigation Database to file a refreshed mitigation plan this year. Miss the window and your traffic is blocked downstream by March 31. If your current carrier hasn't handed you their re-filing paperwork yet, ask.
What VICICarrier customers get
- →Recertified Robocall Mitigation Plan filed under our OCNs — you inherit it by association when you originate through us.
- →Signed compliance declaration (PDF) enumerating the FCC filing IDs, STI-PA cert chain, attestation policy, and KYC program — drop it in any enterprise vendor questionnaire.
- →Your 499-A filing is separate and stays with you; we provide the RMD filing ID you reference in your own annual paperwork.
- →Cross-border traffic: Section 214 authorization is already on file for international originating paths.
Every filer must re-certify. Downstream carriers begin blocking non-certified traffic the first week of April.
We only A-sign numbers hosted with us.
A-level attestation requires a verifiable ownership relationship between the signing carrier and the CLI. If the number isn't provisioned on our platform, we can't honestly attest it. So we don't.
Verified Ownership
Any CLI where we hold the OCN ownership record or have direct verification.
- ✓ DIDs purchased directly from VICICarrier
- ✓ Numbers ported to VICICarrier from another carrier
- ✓ Toll-free numbers provisioned on our RespOrg
Third-party CLI
Any CLI where the ownership chain cannot be cryptographically proven to our switch.
- × Third-party DIDs hosted with another carrier
- × Borrowed CLI from an upstream provider
- × Spoofed numbers or unverifiable CLIs
Third-party CLI is the single most common vector for voice spoofing fraud, regulatory takedowns, and downstream carrier blocks. Letting it through would put our OCN — and every other customer on our platform — at risk. If you want to use an existing number as CLI, port it to us first. Porting is free, typically completes in 3–10 business days, and once the number lives on our platform it gets A-attestation on every outbound call.
Stop signing at B. Port to an A-attested OCN.
Port-in is free, carries a credit for the first month of DID rental, and preserves the audit trail your next auditor is going to ask about.
