AI phone agent
What is an AI phone agent for a small business?
It's a voice agent that answers and makes your business calls. It picks up when you can't, answers questions from your own information, books the job or appointment, and puts urgent callers through to you.
That call came in after the office closed. Without an agent it goes to voicemail and the homeowner calls the next company on the list. With one, the visit is on the calendar and the technician has the ZIP code and the symptom before they leave in the morning.
- Bookings go into your calendar through Cal.com (which syncs with Google Calendar), or into your own system through its API.
- Questions about pricing, service areas and hours are answered from your website and documents.
- Every call is recorded and transcribed. The basics are on the AI receptionist page.
Spanish call
English and Spanish
Can the AI receptionist speak Spanish?
Yes. Voice agents speak American English and Spanish, and replies on WhatsApp and website chat run in Spanish too. Give Spanish-speaking callers an agent that answers them in Spanish.
Pick voices from the voice library, filtered by language, accent, gender and age. Beyond English and Spanish, voice agents speak 50 languages in all — Mandarin, Vietnamese, Korean, Filipino, Portuguese and Russian among them.
Calling hours
When can the AI agent make outbound calls?
Whenever you set it to. You choose calling hours and days for each campaign, read on the called person's local time, and callbacks and campaign calls wait for them. Set them inside 8 a.m. to 9 p.m. local time, the TCPA window — the platform doesn't impose a window of its own.
Some states set narrower hours or extra rules, so set each campaign's hours to match. Campaigns also give you pacing, smart retry, voicemail detection, callback scheduling (“call me back after five”) and A/B testing of opening lines. See voice AI agent for the full list.
TCPA
What does the TCPA mean for AI phone calls?
You are responsible for it. The FCC treats AI-generated voices as artificial voices under the TCPA, so calls made with them need the called person's prior express consent — written consent for marketing calls — and telemarketing must respect the National Do Not Call Registry.
We don't scrub numbers against the Do Not Call Registry or check consent for you. The product gives you tools such as calling hours you set per campaign, a do-not-contact list you keep, an opening line that says who is calling and why, and a recording, transcript and outcome for every call. Answering your own inbound calls is a different matter from outbound marketing, and it's where most small businesses start. Take legal advice before you run outbound campaigns.
Your number
Can I use my own Twilio, Telnyx or Plivo number?
Yes. Connect your carrier account and the agent answers and calls from your number, and you keep paying your carrier directly. We don't rent US numbers.
- Twilio: enter your Account SID and Auth Token and we set the number up in Twilio — nothing else to paste.
- Telnyx: one API key; we create an application on your account and assign the number. Telnyx calls the US and Canada by default.
- Transfer to a person and voicemail detection work on Telnyx and Plivo numbers. An imported Twilio number answers and records, but can't transfer or detect voicemail.
- One agent can call out from numbers on several carriers and pick per call.
Data
Where is my data stored?
In the United Kingdom, in London. We don't offer US data residency today.
Calls are processed partly outside the UK — speech recognition in the EU, the voice and the language model in the US — under UK transfer safeguards; the privacy policy sets out the detail. If your contracts require customer data to be stored in the US, we are not the right fit yet. A new workspace starts in your own time zone.
Examples
Which US small businesses is it built for?
Businesses that lose work when the phone rings out: home services, dental and medical offices, med spas, realtors and law firms.
01 — Phoenix, AZ
HVAC company
After-hours no-cool calls booked into the first morning slot, emergencies put through to the tech on call.
02 — Denver, CO
Dental office
Cleanings booked and rescheduled, new-patient questions answered, anything clinical passed to the front desk.
03 — Miami, FL
Med spa
Consultations booked in English or Spanish, and the same agent answering the spa's WhatsApp.
04 — Atlanta, GA
Realtor
Buyer leads from listings called back inside your calling hours, qualified, and booked for showings.
05 — Chicago, IL
Law firm
New-matter intake the way your form asks it, consultations booked, and the agent set never to give legal advice.
06 — Dallas, TX
Roofing contractor
Storm-damage calls logged with the address and the damage described, and estimates booked on the calendar.
Billing
How is billing handled?
In US dollars, by card, through a merchant of record that handles sales tax. Prices are on the pricing page.
Agencies can resell the platform under their own brand, domain and prices — see white label for agencies, included on every paid plan. Customers who message rather than call can reach the same agent through the WhatsApp Business API.
