Call Clearance
For businesses whose AI makes outbound calls

Check the number
before you call it.

Send us the number first. We check the Do Not Call lists, whether the person told you to stop, whether you have their permission on file, whether it's a legal hour to call them, and whether the number belongs to someone known for suing over calls. You get back yes or no in under a second, and we keep the record in case anyone asks later.

Your AI can dial a thousand numbers before anyone checks a list.

Calling someone on the Do Not Call list, or someone who told you to stop, costs $500 to $1,500 per call if they sue. These cases usually arrive as class actions, so it's rarely one call. Retell, Vapi and ElevenLabs all say in their own documentation that this part is your responsibility. This is the piece that handles it.

Permission in one place

When someone agrees to be called, save it here: who, when, and how you got it — a web form, a text reply, a recorded call, something signed. The check reads this before every call.

The lists that matter

The national Do Not Call registry, the state lists, and a list of people known for suing over calls. The government requires each business you call for to be registered on its own, so we set that up for each of them.

Proof, if anyone asks

Every answer goes into a log where each entry is sealed to the one before it, so nothing can be quietly changed later. Pull a file for any number showing the permission you had and every check we ran. The records are yours.

What we check, in this order

Six things, and we stop at the first problem. Everything gets written down, including anything we couldn't check and why.

1Told you to stopAnyone who told you to stop calling, across every business on your account.
2Known for suingPeople known for suing companies over calls, and the lawyers who send the letters.
3National listThe national Do Not Call registry, checked under each business's own registration. A match stops the call, unless you've told us written permission outranks it.
4State listsState Do Not Call lists, picked by the number's area code. Same rule as above.
5Permission on fileWhether you have permission on file for this number, this business, and calls or texts.
6Calling hoursWhat time it is where the phone is. Calls are legal there between 8am and 9pm.

List who you call for

Every business you make calls for gets its own record. We handle their government registration and state list setup, because the law treats each one separately.

2

Save permission when you get it

Send it over whenever someone agrees to be called, from your forms, your texts, your AI or your CRM.

3

Ask before every call

Send us the number and who you're calling for. You get back yes or no, with the reason.

4

One “stop” covers everyone

When someone asks you to stop calling, tell us once. That number is off limits for every business on your account from that second.

How you plug it in

Two ways to do it, and either way the check happens before the phone rings. Connect your Retell or Vapi account and let us place the calls, or have your own software ask us first.

Your software, or your connected Retell or Vapi account, asks Call Clearance before each call and gets yes, no, or an error to treat as a no; every answer is saved. Your software asks us before each call Retell or Vapi connected once, we call on a yes number + client CALL CLEARANCE 1 Asked you to stop 2 Known for suing 3 National Do Not Call * 4 State Do Not Call * 5 Permission on file 6 Calling hours * a match still stops it unless your account says permission outranks it first problem stops it, one record allow make the call block don’t call, reason saved error or timeout treat as no: don’t call, retry tamper-proof log you can export
  1. Your software sends us the number and which business it's calling for.
  2. You get back yes or no, the reason, and a record number.
  3. Only call on a yes. If it says no, or something goes wrong, don't call.
  4. Send us permissions and stop requests the same way. Ask for a number's file whenever someone wants proof.

Works from any language or workflow tool. Step by step on the setup page; the technical reference is at api.callclearance.com/docs.

  1. Give your agent our tools: one address, one key. That's the setup.
  2. It gets five: check a number, save permission, record a stop request, pull a file, list the businesses you call for.
  3. The tools tell it to check before every call. It can ask, save and look things up, but it can't change the rules. A person sets those on your account.
  4. Same key, same penny a call.

For agents that decide who to call and place calls through tools: Claude, your own agent stack, workflow agents. A voice agent that is already on the call is too late to check; for Retell or Vapi, connect your account instead.

  1. On your dashboard, pick Vapi and paste your private API key. We check it and list your assistants and numbers.
  2. Pick the number and the assistant your calls go out on.
  3. Wherever you start calls today, send them to Call Clearance instead, with the client and the number. On allow we place the call through your Vapi account. On block nothing is dialed.

Why not a tool inside the assistant? It only runs once the call is connected, after the phone has rung. The check has to come before the call is placed.

  1. On your dashboard, pick Retell and paste your Retell API key. We check it and list your agents and numbers.
  2. Pick the number calls go out from. The agent defaults to that number's outbound agent.
  3. Wherever you create calls today, send them to Call Clearance instead, with the client and the number. On allow we place the call through your Retell account. On block nothing is dialed.

Retell has no hook that can stop a call before it's dialed, and a tool inside the agent runs after the phone has rung. So the check sits in front of the call request.

What the proof looks like

When someone asks whether you were allowed to call a number, you send one file. It shows the permission you had, every check we ran, what we answered, and a seal proving nobody edited it afterwards.

  • One number, everything on itEvery check and answer for that number, in order, with dates and times.
  • The permission you hadCalls or texts, where it came from, when you got it, and a fingerprint of whatever you attached.
  • Tamper-proofEach entry is sealed to the one before it. Change anything and the seal breaks, visibly.
  • PDF or data fileA PDF for whoever's asking, a data file for your systems. Same information.
Consent, checks and opt-outs are written as linked entries; each carries the hash of the one before it, and the whole chain exports as one report. Consent recorded, Sep 2 web form, voice, evidence attached and hashed 4b77…0c9d each entry carries the hash of the one above Check, Sep 11 six checks ran, all clear allow 9f3c…e21a Asked to stop, Sep 14 said stop on a call; blocked for every client from now on c41d…77b0 Check, Sep 15 stopped at the opt-out list, nothing dialed block 7a19…d3e4 One report per number, as PDF or data

Questions we get

Short answers. Anything else, email us.

Does this make me compliant?

No product can. What it does is run the checks you're expected to run, before every call, and keep proof you ran them. Whether the way you collect permission holds up is a question for a lawyer. We give you the records; they give you the advice.

Whose government account is the national list checked under?

Each business's own. The rules say the company doing the selling has to hold the subscription, so we set one up for each of them. Until that's in place, the national check comes back as “couldn't check” rather than “clear” — in the answer and in your records. We don't paper over it.

What happens if the check is slow or down?

Treat it as a no and don't call. The tools we give your agent say exactly that. A call you skip costs you almost nothing. A call you can't defend can cost $500 to $1,500.

Can the agent change the rules?

No. Your agent can ask questions, save permissions and look things up. It can't change what counts as permission, the hours you call, or any list setting. A person changes those on your account.

Who owns the records?

You do. Download any number, any business, or all of it, any time, as a PDF or a data file. If you leave, you take it all with you.
