AI Voice Agents
Never miss a call. Never miss a booking.
What is an AI voice agent?
An AI voice agent is software that answers and makes phone calls in natural spoken language. It listens with speech-to-text, decides what to say and do with a language model, replies with text-to-speech, and takes actions during the call, such as checking availability and booking an appointment. Unlike an IVR menu, callers speak normally and can interrupt. Unlike voicemail, every call ends with structured data and a next step.
LIVE DEMO · CALL IT RIGHT NOW
Talk to our AI receptionist.
This is a real AI voice agent we built for dental clinics. Call the number, book an appointment, try to trip it up. It answers 24/7, never puts anyone on hold, and books directly into the calendar.
- Answers every call, instantly
- Collects name, reason & details
- Books the appointment on the call

Built with Twilio · real-time WebSockets · custom booking logic
THE PROBLEM
Businesses lose revenue every day to missed calls, hold queues, and after-hours voicemail. Hiring reception staff for 24/7 coverage is expensive, and every unanswered call is a customer who books with a competitor.
OUR SOLUTION
We build production-grade AI voice agents on Twilio and real-time speech infrastructure that answer instantly, hold natural conversations, collect caller details, answer questions, and book appointments directly into your calendar, in your brand's voice, around the clock.
HOW IT WORKS
How an AI voice agent handles a call
- 01
The call connects
Your existing number forwards to a Twilio line, or we set up a new one. The agent picks up straight away, day or night, with a greeting in your brand's voice.
- 02
It listens in real time
Audio streams over WebSockets into a speech-to-text pipeline, so the agent understands the caller while they are still talking and handles interruptions (barge-in) naturally.
- 03
It reasons against your rules
A language model, grounded in your services, hours, and FAQs, decides the reply. Guardrails keep it on script for anything it must not improvise, such as medical or legal advice.
- 04
It acts during the call
Webhooks check calendar availability, book or reschedule the appointment, and record the caller's name, reason, and contact details while the caller is still on the line.
- 05
It leaves a full record
Every call is recorded, transcribed, and logged in an analytics dashboard. Calls that need a person can be passed to your team with the details already captured.

Use cases
- Dental & medical clinic receptionists
- Real estate inquiry and viewing bookings
- E-commerce order status and support lines
- After-hours answering for service businesses
Benefits
- Answer 100% of inbound calls, day and night
- Cut reception overhead while improving response times
- Every call captured as structured data, not voicemail

COMPARE
AI voice agent vs. voicemail or an answering service
| Criterion | AI voice agent | Voicemail or answering service |
|---|---|---|
| Availability | Every call, 24/7, no hold queue | Business hours, or a shared operator pool |
| Bookings | Booked into your calendar during the call | A message; someone calls back later |
| Data captured | Structured fields, transcript, and recording | Free-text messages |
| Busy periods | Takes simultaneous calls without extra staff | Callers wait, or hang up |
| Consistency | Same script and rules on every call | Varies by operator and time of day |

FAQS
AI Voice Agents: common questions
How much does an AI voice agent cost?
It depends on call volume, the systems it has to connect to (calendar, CRM, practice management), the languages it needs, and how much custom logic the calls involve. We do not publish fixed prices. On a free discovery call we scope the agent, then send a proposal with milestone-based pricing.
Can an AI receptionist book appointments into my existing calendar?
Yes. Booking runs through webhooks into your calendar or scheduling system during the call, so the appointment exists before the caller hangs up. We confirm which system you use during discovery and build the integration for it.
Will callers know they are talking to an AI?
They should. We recommend a short disclosure in the greeting, and in some places and use cases disclosure or consent is a legal requirement. Our call flows are designed to be TCPA and consent aware in the US, GDPR aware in the UK and EU, and aligned with the Privacy Act in Australia.
What happens when the AI cannot answer a question?
It follows the fallback you choose: take a message with the caller's details, offer a callback, or pass the call to a person. It is built to say it does not know rather than guess, and those calls show up in the transcripts so you can add the answer.
Which languages can the voice agent speak?
Multi-language support and regional accents are part of the build. Tell us which languages your callers use and we will confirm quality in each before launch.
