Answer every call your team can't take

Every caller gets an answer, leaves a message, or reaches your on-call person.

The agent answers hours, holiday closures and parking rules from what you provide. It checks today's hours with a webhook and says when it doesn't know.

What to check before you pick an AI answering service

What is an AI answering service?

An AI answering service is a voice agent that picks up when your team can't, whether the office is closed or every line is busy. It answers from your hours and policies, takes a message someone can act on, and pages your on-call person by rules you write.

  • Check office hours
  • Save caller message
  • Page on-call technician
  • Transfer to on-call

What happens to a ceiling leak at 11 p.m.?

A tenant with water coming through the ceiling and a resident with a lost parking permit dial the same number. The leak pages the on-call technician and the caller gets transferred. The permit becomes a message with the unit, a callback number and the reason.

I lost my parking permit and need a new one.

I can leave that for the office. What's your unit and the best number to reach you?

Unit 4B, 206-555-0142.

Is an AI phone answering service better than voicemail?

Voicemail records everyone the same way and leaves you to sort it later. The agent asks follow-up questions, reads the callback number back and confirms a message only after your system saves it. Anyone mentioning fire, gas or injury hears to hang up and call 911.

Which is the best AI answering service?

The one that fits your calls, so ask where messages land, who decides what's urgent and whether you can read every call, then price it with LLM usage and telephony counted. Start from your trade too. Versions exist for after-hours cover, HVAC, plumbing, towing, law firms, physicians and property management.

Caller helped

Did the caller get an answer, leave a message with a callback number, or reach the on-call person before the call ended?

What an AI answering service for business does with missed calls

An AI answering service for small business or an apartment building has the same job. Sort the call, capture it properly and bother a person only when it's worth it.

Urgent means what you say it means

You write the list. At Pinecrest that's an active leak, no heat or a lockout, so a Sunday noise complaint waits for the office and the technician stays asleep.

Messages arrive complete

The agent asks for the unit, a callback number and the reason, then reads the number back. Nobody spends the morning decoding a half-finished voicemail.

Daytime overflow gets covered too

With every line busy at noon, the agent picks up and saves a message for the next free person, so a deposit question doesn't ring out.

Each message lands in your own system

Send it to a helpdesk, a CRM or a shared inbox. Callers hear it's saved only after that system confirms, so a dropped message doesn't pass as a kept promise.

You can read every call

Recordings and transcripts come with each call, which tells you whether your urgent rules work. Shared operator pools rarely give you that much.

It answers phones, and that's where it stops

Doors and leaks are beyond it, and it won't go past your information. Whatever it can't answer becomes a message or a page.

Phone speech that holds up when a caller is stressed

Someone with water on the floor talks fast and doesn't wait for a prompt. Cartesia's speech models are built for that kind of call.

  • 24/7answers every call, at any hour

Keeps up with a rushed caller

Callers blurt the unit number, stop, then add that it's dripping fast. The agent takes it in order and doesn't talk over them.

Your rules, your choice of LLM

Choose the LLM, then give it the tools that check office hours, save a message, page on-call and transfer the call.

A steady voice for a bad night

The voice library has plenty of calm options. Choose one for your office, so a worried caller hears your name and someone in control.

AI, live operators or voicemail for missed calls

Most owners shopping for an AI call answering service are already paying for one of the other two, or quietly losing calls to it.

Launch an AI answering service in three steps

Start building
  1. Clone the night desk

    Copy this agent, then replace Pinecrest's hours and policies with yours and write your own urgent list.

  2. Connect your inbox and pager

    Point messages at your helpdesk, CRM or shared inbox, connect paging and the transfer number, then forward your line to the agent.

  3. Call in a fake leak

    Report an active leak, then a lost parking permit. Check that only the first paged on-call, and go live when both transcripts read right.

Answering service FAQs

What is an AI answering service?

A voice agent that picks up when your team can't. It answers from your hours and policies, takes messages, and pages your on-call person for urgent calls.

Is there an AI phone answering service for small business?

Yes. The AI receptionist for small business page shows the agent set up for a business of one or two people: it quotes your price list, books open slots and rings you only for the calls you pick.

Can an AI answering service screen my calls?

Yes, by the rules you write. The agent asks why each person is calling and checks the answer against your urgent list. Urgent calls page your on-call person and transfer. Everyone else gets an answer from your information or leaves a message with a callback number, so your phone stays quiet for the routine ones.

What is the most affordable AI answering service?

That depends on your call volume. Per-minute pricing usually suits a line with few or short calls, and a flat plan can win on a very busy one. Work out your monthly minutes, then add LLM usage and telephony. This agent is $0.03 per minute plus those, so a quiet night costs little. See pricing.

Is there a free AI answering service?

Not for a working phone line. Cartesia's free plan includes $1 of agent calls a month, which is enough to build the agent and test it on calls. Once real callers reach it, you pay for call minutes at $0.03 per minute, plus LLM usage and telephony. See pricing.

How do I set up an AI answering service?

Clone the sample agent on this page, then replace its hours and policies with yours and write the list of calls that should page someone. Connect the place messages should land, such as a helpdesk or shared inbox, and set your on-call number. Forward your line to the agent, or bring your own Twilio account or SIP trunk, and place test calls before going live.

What is the best AI answering service?

Choose on what it does with your calls. Check that it answers only from information you approve, saves each message in your own system, pages or transfers urgent calls by rules you set, and records and transcribes every call. Then compare the price per minute with LLM usage and telephony counted. This agent is $0.03 per minute plus those.

Is an AI answering service the same as voicemail?

No. Voicemail only records the caller, while the agent asks follow-up questions, answers from approved information, and pages or transfers to a person.

Can an AI answering service answer calls after business hours?

Yes. Point your number at the agent and it answers 24/7, taking messages when the office is closed and paging someone for urgent calls.

How does an AI answering service work?

You point your number at the agent and give it your hours, policies and urgent rules. It answers from that information, asks for a callback number and the reason, and saves the message wherever you choose, such as a helpdesk, a CRM or a shared inbox. It tells the caller the message is saved only after that system confirms it.

Can an AI answering service handle urgent or emergency calls?

Yes. It pages or transfers to your on-call person when a call matches the criteria you set, and tells callers with a fire, gas leak or injury to call 911.

How is an AI answering service different from a live answering service?

A live answering service has operators who take messages from a script you write, and one operator covers many businesses. The agent works from the same script, also answers from your approved information, and saves each message in your system. Every call is recorded and transcribed, so you can read how each one went.

How much does an AI answering service cost?

The bill follows the calls that reach the agent. It's $0.03 per minute of call time, so a thirty-second hours question costs less than a long emergency call. LLM usage is billed separately, and 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 to test with before you pay. See pricing.
