Turn a campaign list into booked visits

The agent calls every number on your consented list during the hours you set, makes one offer, and books the visit on the call.

The agent calls each number you load from a list you hold consent for, at the hours, pacing, and retries you set, and opens with the customer's equipment and last service.

AI cold calling, and the consent question that comes first

What is AI cold calling?

AI cold calling means a voice agent phoning people who didn't ask for the call, with one offer and one goal. It dials at the hours, pacing and retries you set, books the next step on the call and saves an outcome for every number.

  • Load the customer and equipment
  • Find technician availability
  • Book the tune-up
  • Save the call outcome
  • Transfer to the office

Can I use cold calling AI on any list?

In the US, calls made with an AI voice need prior express consent under the TCPA. So this fits lists you hold consent for, such as past customers. It isn't a way to blast strangers, and you own the list and the consent.

get_customer_contextFurnace, last serviced over a year ago

Hi, this is Noor, an AI assistant calling for Hollowell Heating and Air. Am I speaking with Gabriel Ruiz?

Yes, that's me.

What does conversational AI for cold calling sound like?

Noor, the tune-up campaign agent, loads the customer's equipment and last service, opens with that, offers open times from the technician calendar and books on the call. A heating and air office busy with inbound calls never has to dial the list by hand.

Visit booked

Did the customer book a tune-up visit before the call ended?

What happens when someone says stop?

The agent saves do not call and ends the call, and that number won't be dialed again. It quotes no prices, so repair and price questions transfer to your office. Calls go to US numbers only.

  • Load the customer and equipment
  • Find technician availability
  • Book the tune-up
  • Save the call outcome
  • Transfer to the office

How a campaign list turns into a booked week

Conversational AI cold calling is only as good as the list and the offer. Assuming you have both, this is what changes for the people running the campaign.

The whole list gets called

Hours, pacing and retries are yours to set, and the agent keeps dialing after your office has moved on, so a seasonal offer reaches everyone before the season.

The opener is about them

"Your furnace was last serviced over a year ago" lands better than a pitch. The agent reads it from the customer record before it speaks.

Booked on the call

Gabriel takes Thursday at 8 AM from the technician calendar, and his thermostat note goes along with the booking.

One outcome per number

Booked, call back, not interested or do not call, saved in the fields your team already reads. Nobody reconstructs a campaign from sticky notes.

Stop means stop

When Pablo asks to stop, the agent saves do not call and hangs up politely. That covers every campaign, and the number won't be dialed again.

It won't improvise a price or a promise

The agent quotes nothing and offers only what your tools return. It also won't talk anyone out of a no. Price and repair talk goes to your office.

An outbound voice that sounds like a neighbor, not a robocall

People decide in a few seconds whether to stay on. Cartesia's speech models keep the opening quick and natural, and the agent says up front that it's an AI.

Hears a no the first time

When someone cuts in with "not interested" or "stop calling", the agent stops and acts on it instead of finishing the pitch.

One offer, one set of tools

Choose the LLM, then give it the tools that load the customer and equipment, find visit times, book the tune-up and save the outcome.

A voice for your name on the line

Past customers know your business and will judge the call by how it sounds, so choose from the voice library with them in mind.

Agent, dialing rep or recorded blast on a consented list

Shoppers for the best AI cold calling software usually compare it with reps on the phones. Recorded broadcasts are cheap, and they can't hold a conversation.

Launch an outbound calling agent in three steps

Start building
  1. Clone the tune-up campaign

    Copy this agent, then rewrite the offer, the rules and the name it calls under.

  2. Connect your list and calendar

    Load a list you hold consent for, link the customer record, technician calendar and outcome fields, and set hours, pacing and retries.

  3. Put your own number first

    Add yourself to the list and take the call. Book once, then say stop, and go live when both outcomes save correctly.

Outbound campaigns FAQs

What is AI outbound calling and how does it work?

AI outbound calling is a voice agent that calls a list you hold consent for with one offer, such as a fall tune-up for past customers who agreed to calls. It dials at the hours, pacing and retries you set, books the next step on the call, and saves an outcome for each number.

What is AI cold calling?

A voice agent that calls people who did not ask for the call, with one offer. In the US, calls made with an AI voice need prior express consent under the TCPA, so cold calling AI fits lists you hold consent for, such as past customers. Read our guide to AI cold calling.

Does AI cold calling software respect opt-outs and calling hours?

Yes. The agent dials only in the calling hours you choose, skips your do-not-call list, and saves do not call when someone asks to stop. You own the list and the consent.

How is AI outbound calling different from an AI auto dialer?

The AI auto dialer covers pacing, retries, voicemail, and batch runs. Outbound calling covers the campaign itself, meaning the offer, what the agent says, and the outcome for each number.

When should I use lead follow-up or an AI SDR instead of AI outbound calling?

Use AI lead follow-up for a new form or missed-call lead waiting on a first call, and an AI SDR to qualify a new lead. Use outbound calling when one offer goes to a whole list.

Can the agent transfer a customer to our office?

Yes. Price and repair questions transfer to your office, and you control exactly when the agent transfers.

How should we measure an AI outbound calling campaign?

Evaluate the agent against your key success criteria. For example, you can measure what percentage of calls end with a booked visit, or what percentage of numbers on the list the agent reaches.

Is AI cold calling illegal?

Not by itself, but consent decides it. In the US, the TCPA requires prior express consent for calls made with an AI voice, so calling people without it can break the law. The agent skips your do-not-call list and saves stop requests, and you own the list and the consent. This isn't legal advice, so check your plan with counsel.

How do I use AI for cold calling?

Start with a list you hold consent for and a single offer. Clone the sample campaign, rewrite what the agent says, and connect your customer records and calendar. Set your calling hours, pacing and retries. Put your own number on the list first, then read the transcripts and the outcome for each call before you widen the campaign.

What AI cold calling software should I use?

Pick one that books the next step on the call, saves an outcome for every number and honors stop requests the moment someone asks. Check that it says it's an AI and works only from your records. You can answer a sample campaign call on this page to hear how this one handles it.

What is the best AI tool for cold calling?

The best tool for you holds a real conversation, books the next step on the call and acts on a stop request right away. It should say it's an AI and work only from your records. Try it on a small list you hold consent for, then read the transcripts before you widen the campaign.

How to automate cold calling with AI on a consented list?

Load the list, write one offer and set your calling hours, pacing and retries. The agent then dials each number, opens from the customer's record, books on the call and saves one outcome per number. Price and repair questions transfer to your office, and stop requests become do not call.

How much does AI outbound calling cost?

Voicemails and quick noes cost little, because you pay for call time at $0.03 per minute, and the longer calls tend to be the ones that book. LLM usage is billed separately. A Cartesia phone number adds $0.014 per minute, or nothing if you bring your own Twilio account or SIP trunk. The free plan includes $1 of agent calls a month, so you can test a small list before you pay. See pricing.
