If you're putting an AI on your phone lines, the legal exposure does not move to the vendor. It sits with you, because it's your list, your brand and your callers. That's the frame for all four of these questions.
Ask them live, on a call, and make them answer specifically. Vague answers are the finding.
Ask them to trace it. Not the general answer about how they handle data, the specific answer about the specific list they're about to dial. If the answer is vague, the risk sits with you, not them.
A good answer sounds like a chain of custody. This list came from this source, collected on this date, under this disclosure, and here's the record. A bad answer sounds like a description of their philosophy about compliance.
Ask what happens to a number that appears on a do-not-call registry after you bought the lead. Ask how often they re-scrub, and against what. A vendor who scrubs once at import and never again is handing you a list that decays into a liability.
Separate the two motions in your head, because the rules are not the same. Somebody who called your number and left a message has given you a very different thing than a name on a purchased list. If a vendor talks about both the same way, they haven't thought about it hard enough.
Inside the first ten seconds, unprompted, on every call. Anything later is a decision to see whether the person notices first.
Watch for the workaround here. Some vendors will tell you the agent discloses when asked. That is not disclosure, that's a trapdoor. The question you're asking is whether a person who never thinks to ask still finds out, and the answer needs to be yes.
There's a business reason on top of the legal one. A seller who figures out mid-call that they've been talking to a machine that was pretending otherwise does not become a lead. They become somebody who tells the story about your company. Disclosure early costs you almost nothing and protects the only thing you can't buy back.
Ask to hear it. Make them play a real recording, not a demo script, and count the seconds.
Make them demo that exact call, live, on the spot. Not the good call. That one. The response should be immediate, unconditional, permanent, and applied across every channel they run for you.
Unpack each of those four words, because a vendor can fail on any one of them while passing the other three.
Immediate means in the same breath. Not after one more question, not after a retention attempt. If the agent tries to keep talking, it fails.
Unconditional means it does not ask why. A machine asking a person to justify an opt-out is the worst possible version of this interaction.
Permanent means the record survives a list re-import. Ask specifically what happens when you upload a new file containing that same number next quarter.
Across every channel means the opt-out propagates. If it stops the calls but a text goes out next Tuesday, you did not honor anything.
Also ask about the near misses. Not everybody says the magic words. People say stop calling me, I'm not interested, don't contact me again, and lose your number. Ask how the agent handles each of those, and whether the bar for stopping is lower than the bar for continuing. It should be.
The lead's, not yours. If a vendor has to think about that answer, they built it in one time zone and never tested it in another.
This one is a proxy question. Nobody gets calling windows wrong on purpose. They get it wrong because the system was built and tested in a single place and nobody ever pushed a lead from three time zones over through it. When a vendor answers this crisply, it tells you they've handled the boring parts. When they pause, it tells you what else might not have been tested.
Follow up with how the time zone is determined. Area code is the common shortcut and it's wrong often enough to matter, because people keep their numbers when they move. Property address is better. Ask which one they use and what happens when the two disagree.
Ask them to make the agent take a question it has no answer for. It should say it doesn't know and route to a human. What you're watching for is whether it invents something. An agent that fabricates a detail about your buying criteria or your timeline is creating a problem that lands on you at the closing table, not on the vendor.
Ask where they're stored, how long they're kept, whether you can export them, and what happens on the day you cancel. Your call recordings are your training material and your record if a call is ever disputed. Find out before you need them, not after.
Ask whether the numbers you'll be dialing from are yours or shared with other customers. Shared numbers carry other people's history, and a number that gets flagged by carriers starts showing up as spam risk on the seller's screen. At that point your answer rate drops and no amount of script quality fixes it.
Ask specifically about STIR/SHAKEN attestation and who registers the numbers. A vendor who can explain how your calls get signed has thought about whether anybody actually picks up. A vendor who hasn't heard the question will be selling you dials that go straight to a spam label.
Ask what happens when a number does get flagged. There should be an answer that isn't we'd get you a new number, because rotating numbers to escape a reputation problem is the behavior that creates reputation problems.
The tell isn't only in the answers. It's in what they raise before you do.
A vendor who has actually run this at volume will bring up calling windows on their own. They'll mention that they scrub against do-not-call lists on a schedule, not once. They'll tell you which states have their own rules on top of the federal ones. They'll say plainly that the exposure is shared and that they carry insurance, or that they don't.
A vendor who has only built a demo will answer every question you ask correctly and raise nothing. That's the pattern to watch for. Compliance is one of those areas where the depth of somebody's worry is a better signal than the polish of their answers.
Do it in one call, live, with the vendor sharing their screen. Do not accept a document. A written answer to any of these is a description of an intention. A live demo is the thing itself.
Write down each answer as you go and score it as specific, vague, or deflected. You're not looking for a perfect record. You're looking for the shape: a vendor who is precise on three and hand-waves the fourth has told you exactly where they cut the corner.
And ask them to run the bad call, not the good one. Any vendor can play you a smooth demo. What you're buying is what happens on the calls that go sideways, because those are the ones with your name on them.
None of this is legal advice and I'm not a lawyer. It's the diligence list. If a vendor clears all four and you're still putting them on a large list, have somebody who does this for a living read the contract before you sign it.
