Originating provider compliance
Attestation for originating carriers.
VoIP Radar signs every call your switch originates with the right A, B or C attestation — based on real KYC and number-ownership data, not guesswork. Keep downstream partners confident and your RMD certification defensible.
The three levels
A / B / C, assigned automatically
Get attestation wrong and your calls get labeled or blocked downstream — or your network attracts tracebacks. VoIP Radar decides the level from customer identity, LOA and number records on every call.
Full attestation
You have authenticated the customer and verified they are authorized to use the calling number — e.g. a number you assigned to them or one they have proven they own.
Partial attestation
You know the customer who originated the call, but cannot confirm they are entitled to the calling number — common for bring-your-own-number trunks.
Gateway attestation
You are passing along a call you cannot authenticate, such as traffic received from an international or upstream gateway.
Built for originating VSPs
Attestation you can defend in an audit
KYC-driven decisions
Every attestation decision is tied to the customer's KYC record, so you can explain any signed call after the fact.
Signing at the edge
Sign INVITEs at line rate using your certificate — no changes to your softswitch logic required.
Non-IP paths
Plan for calls that cross TDM interconnects or legacy trunks where SIP signatures don't survive.
Automatic downgrades
Drop to B or C when a customer fails re-verification or a number leaves their authorized inventory — before a partner complains.
Audit-ready logs
Each signing event is stored with level, reason and customer snapshot, ready to support your mitigation plan.
Number-ownership checks
LOA, porting and assignment records confirm when a customer can legitimately present a number.
Why attestation quality is under the FCC's microscope
Regulators and industry have made it clear that A attestation should mean what it says: the provider knows the customer and the customer's right to use the number. Handing out A attestation by default — simply because the call started on your switch — undermines the framework and invites scrutiny.
VoIP Radar turns attestation from a manual policy setting into a logged, explainable decision tied to real identity data. That is the difference between a quick answer to a downstream carrier and a lengthy inquiry.
