The policy is only worth what the enforcement is worth
Plenty of carriers publish an acceptable use policy. Fewer act on it. Here is exactly how we enforce ours — what we check before you send a call, what we watch while you send them, and what happens when something falls outside the line.
How enforcement actually works
Each layer catches something the previous one cannot.
Know the customer
Before a single call routes: entity verification, ownership and control, named compliance contact, documented use case, expected traffic profile and evidence of the right to use every calling number.
Sign the call
STIR/SHAKEN attestation assigned from what we have actually verified. Full A-attestation requires verified number ownership — we do not hand it out to fill a checkbox.
Watch the traffic
ACD, ASR, short-duration ratio, concurrency shape and attestation mix, monitored continuously per trunk and per campaign against published thresholds.
Answer the traceback
Industry traceback requests answered within 24 hours, every time. An unanswered traceback is how a clean network becomes a dirty one.
The numbers we hold every account to
We publish these deliberately. You should know what triggers a review before you sign, not discover it during an incident.
| Metric | Expected | Review trigger | What it tells us |
|---|---|---|---|
| Average call duration | Above 90 seconds | Below 60 s sustained | Genuine conversations last. A collapsing ACD is the clearest dialer signature. |
| Answer-seizure ratio | 35% and above | Below 25% sustained | Low ASR means stale, unconsented or invalid lists. |
| Short-duration ratio | Below 15% | Above 25% sustained | The primary indicator of pinging, scanning and abandoned calls. |
| Concurrency profile | Matches contracted channels | Sudden multiples of baseline | Step changes indicate an unapproved dialer or a compromised endpoint. |
| Complaint rate | Effectively nil | Any verified complaint | Complaints become tracebacks, and tracebacks become regulatory exposure. |
| Attestation mix | Predominantly A | Persistent C attestation | Low attestation degrades delivery and signals unverified originators. |
Full definitions and the escalation path are in Section 5 of the Acceptable Use Policy.
The rules we operate under
US voice is one of the most heavily regulated services there is. We treat that as an operating discipline rather than a compliance burden.
- TRACED Act & STIR/SHAKEN. Calls signed with attestation reflecting what we have verified, and participation in the industry traceback process.
- TCPA & Telemarketing Sales Rule. Customers must hold and evidence the consent their call type requires; we audit on request.
- Truth in Caller ID Act. Misleading caller ID, number rotation and snowshoeing are prohibited and monitored for.
- Section 222 & CPNI. Strict handling of customer proprietary network information, with authentication before disclosure.
- CALEA & lawful access. Valid legal process required, narrowly scoped responses, customer notified where legally permitted.
- Kari’s Law & RAY BAUM’S Act. Direct 911 dialling, on-site notification and dispatchable location supported for MLTS deployments.
Our escalation path, in order
We prefer to fix a configuration problem with you. We will not hesitate on a consumer-harm problem.
Review
We contact your technical and compliance leads with the specific metrics and the affected campaign. Most issues end here — misconfigured dialling gaps, a bad list, a test left running.
Evidence request
We ask for consent records, lead sources, scripts or number-ownership evidence for the campaign in question. Failure to produce them is itself grounds for suspension.
Technical controls
Rate limits, concurrency caps, destination blocks or campaign-level filtering applied while the review completes.
Attestation change
Attestation level reduced where we can no longer verify the originator or the right to use the calling number.
Suspension
Affected trunks, numbers or sub-accounts suspended. Immediate and without notice where consumer harm, fraud or regulatory exposure is likely.
Termination & referral
Material breach terminated, and the matter referred to regulators, law enforcement, upstream carriers or the traceback consortium as appropriate.
Received a call you should not have?
If you believe a call originated on our network and violated our Acceptable Use Policy, tell us. We investigate every report and we acknowledge within one business day.
Email legal@carrierlinktel.com with the subject “AUP Abuse Report” and include the number called, the number shown on caller ID, the date and time with your time zone, roughly how long the call lasted, what was said or played, and any company or callback number mentioned.
Regulators, carriers and traceback participants: use the same address and mark your request urgent. Tracebacks are answered within 24 hours.
Not sure whether your traffic qualifies?
Send us the profile — destinations, concurrency, average duration, how the calls are initiated and how consent was obtained. We will tell you plainly whether we can carry it.
