AI Voice Agent: Answer Every Call, Book Appointments, Hand Over When Needed
We build voice agents that pick up the phone, understand the caller, check your systems and book, qualify or route the call. An AI voice agent should sound natural, know its limits and pass difficult calls to your team. Pilots start from $1,400.
What an AI voice agent does on a call
Phone calls are still where many customers start. Here is what the agent handles for you.
Inbound calls
AI call answering and AI phone answering: picks up every call, day and night, in the language of the caller, with no queue or voicemail.
Lead qualification
Lead qualification and AI cold calling: asks your questions, scores the lead and sends a summary and transcript to the CRM.
Appointment booking
AI appointment booking: checks the calendar, books, moves or cancels slots and sends a confirmation message.
Answers from your content
Uses your knowledge base for prices, hours and policies instead of guessing.
Safe handover
Transfers to a person when the caller asks or the agent is unsure, with the context of the call.
Review and compliance
Call recording, transcripts and consent rules, so you can audit every conversation.
Why teams build voice agents with us
Many voice bots feel robotic or invent answers. We design for natural speech, limits and measurement.
Published starting price
Pilot from $1,400, with a written scope and a fixed price after a short assessment.
Limits by design
The agent only handles tasks you approve and escalates everything else.
Telephony and integrations

Measured calls
We track answer rate, completed tasks, handovers and caller satisfaction.
How a voice agent project runs
Call analysis
We listen to real calls, pick the top call types and define what the agent should do.
Design the dialogue
We write the flows, the voice, the tone and the rules for handover.
Build and connect
We connect telephony, CRM and calendar and test with real numbers.
Pilot and tune
We run the agent on part of your calls, review recordings and improve every week.
IVR, voice bot or voice agent
The older phone menus and the new agents solve different problems.
| Option | Best for | Limit |
|---|---|---|
| IVR menu | Routing by button press | Rigid, callers dislike it |
| Scripted voice bot | A few fixed questions | Breaks on unexpected wording |
| Voice agent with AI | Varied calls with actions | Needs good content and testing |
| Human team | Complex or sensitive calls | Cost and limited hours |
| Reception and after-hours calls | AI receptionist or AI answering service | Covers nights and peaks |
| Large call volume | AI call center agent | Needs routing and quality review |
Most teams keep a person for complex calls and let the agent handle the repeat ones.

What good voice AI looks like in practice
A voice agent is more than a speech model. It combines speech-to-text (STT), a language model that understands the request, text-to-speech (TTS) for the reply and a telephony layer. Latency matters most: a pause of a second feels like a bad line, so we tune the stack until the conversation flows, and we support barge-in so callers can interrupt. We choose the speech to text API and the text to speech API for latency and language support, not for fashion.
People search for this work as an AI phone agent, voice AI for call centers, voice AI for business, an AI receptionist, an AI calling agent, an AI call center or an AI answering service, and the scope is the same: calls, content, integrations and review. We connect the agent to your CRM through SIP, store call recording and transcripts, and add handover to your team. The agent can be multilingual, so one number serves callers in several languages. For customer service we plan wait times, a transfer to a human, phone number setup and security of call data, and we run a live demo and a short case study of a similar agent before you decide.
We follow consent and privacy rules, including GDPR, mask sensitive data and tell callers they speak with an AI. Voice agent pricing depends on call volume, languages and integrations, and companies that hire voice agent developers from us get a fixed price in writing and a weekly report during the pilot. For appointment booking and lead qualification the first results usually show within weeks. White label builds, inbound and outbound calls and an AI IVR replacement are all in scope.
Questions we get on the first call
What is an AI voice agent?
It is software that answers phone calls in natural speech, understands the request, uses your systems and hands over to a person when needed.
How much does a voice agent cost?
Pilots start from $1,400. The final price depends on call volume, languages and integrations, and is fixed in writing after a short assessment.
Will callers know it is an AI?
Yes. We disclose it at the start of the call, which is also what privacy rules expect. Many callers accept it when the agent is fast and useful.
Can it book appointments?
Yes. It checks your calendar, books, moves or cancels slots and sends a confirmation.
What if it cannot answer?
It hands the call to a person with a summary, or takes a message, depending on the rule you choose.
How long does a pilot take?
Usually three to six weeks, depending on call types and integrations.
Can it make outbound calls?
Yes. Outbound agents can confirm appointments, remind customers about payments, collect feedback or qualify leads, within consent rules and calling hours you set.
Can it replace our IVR menu?
Yes. Instead of pressing buttons, callers say what they need and the agent routes, answers or books, with handover to a person for anything outside its scope.
How do I start?
