Where do the A/B/C attestation levels come from?

The upstream signing carrier, not Orbit and not this page. Orbit resolves your caller ID against ownership, leases, and registered delegate certificates (owned → A, leased → B, certificate-raised BYON → B, else C), signals the level to Devotel's wholesale softswitch, and surfaces the tenant-owned evidence you control.

What does Orbit actually sign on my outbound calls?

Devotel's wholesale carrier softswitch holds the STIR/SHAKEN signing certificate and signs the PASSporT — never higher than the level the platform resolved against your ownership and certificates. Orbit computes the level and surfaces your evidence; the signing authority is the upstream carrier, and the tenant-owned controls below set the posture the softswitch reports back for.

Which STIR/SHAKEN evidence does Orbit surface?

Everything tenant-owned: the attestation floor snapshot, the branded-calling (RCD) profile, the enrolled voice signature, the evidence-to-posture crosswalk, and the ITG traceback case lifecycle. Compliance posture is tenant-owned — Orbit surfaces the controls and records what you set; it never mandates a level.

STIR/SHAKEN attestation checklist

Pick the attestation level you want your outbound US voice traffic to reach, then walk the five tenant-owned reads Orbit ships — the attestation floor, branded calling profile, voice signature enrolled, evidence crosswalk, and the ITG traceback path. Free, no sign-up.

STIR/SHAKEN attestation checklist

Pick the attestation level you want your outbound US voice traffic to reach, mark the reads you already have covered, and see the placement in plain language. Each read is a control Orbit ships as a tenant-operated setting — this page advises, it never enforces.

Attestation level you want your traffic to reach

A — full attestationOnly reachable on numbers you own through Orbit (purchased or ported in). The platform resolves ownership at dial time and signals A to the signing softswitch.B — partial attestationLeased / pool-assigned numbers, or BYON numbers raised from C by a registered delegate certificate (C → B, never A — the deliberate hard ceiling).C — gateway attestationTraffic Orbit cannot tie to an ownership or certificate claim — the level carriers label 'Spam Likely.'

Attestation floor setThe reporting policy declares your target level, downgrade handling, and per-DID inbound floor — what the posture snapshot reports, never a dial-time gate.Policy fields classify what your posture reports; they never raise what gets signed, reroute a call, or block one at dial time.Docs: STIR/SHAKEN posture guide →
Branded-calling profile configuredFor A-eligible traffic, wire the branded-calling (Rich Call Data) profile so the signed PASSporT carries your display name; register CNAM as the fallback for where RCD does not land.RCD rides on full (A) attestation — the name a handset shows downstream rides the signature, not a separate database.Docs: Branded calling (RCD) →
Voice signature enrolledEnroll the voice signature for your outbound lane so the call carries a verifiable identity artifact alongside the attestation level the softswitch signs.The signature is a tenant-supplied artifact, not the network signing itself — enroll it before relying on it for an answer-rate claim.Docs: Voice signatures →
Evidence crosswalk retrievedPull the evidence-to-posture crosswalk so the production behaviour Orbit stakes its correctness on (origination-level resolution to A, B, or C, signalled to the softswitch) maps to the posture you operate.The crosswalk names the CLI commands and the reporting policy that measure each rung — the evidence an auditor asks for first.Docs: STIR/SHAKEN evidence crosswalk →
ITG traceback path understoodSigned traffic carries the downstream obligation to answer Industry Traceback Group requests implicating your originating numbers — log each case, file the disposition, and watch the response deadline.Orbit provides the case-management surface; you log the request, you decide the disposition, you file it with the ITG.Docs: ITG traceback handling →

0 / 5 reads covered

Not all five reads are covered. A-level traffic on the numbers you own is the only real lever — everything below (certificates, branded calling, CNAM) paints over whatever ownership still leaves exposed.

STIR/SHAKEN posture is tenant-owned: attestation levels come from the upstream signing carrier — Orbit resolves your caller ID against ownership, leases, and delegate certificates, signals the level to Devotel's wholesale softswitch, and surfaces the evidence you configure. Nothing on this page attests your traffic or mandates a posture. This checklist is not legal advice — confirm your STIR/SHAKEN obligations with counsel.
