Every Missed Call Is a Customer Calling Someone Else
You can’t answer the phone while you’re on a job, with a patient or asleep. Voicemail doesn’t help much, because most callers hang up and try the next business. An AI answering service picks up instead, so the enquiry stays with you.

What Is an AI Answering Service?
An AI answering service is software that answers your business calls with a natural voice, replies to common questions from your business information, takes the caller’s details and passes the lead to you. Unlike voicemail, it actually talks to the caller and gets the details you need to call back.
How does AI call answering work with zentroVoice?
You connect a phone number or add the website call button. The AI reads your website and FAQs, and you check what it learned. From then on it answers, summarises each call and files the lead.

Built for Businesses That Live on the Phone
An AI answering service suits plumbers, HVAC and electrical contractors, cleaning companies, dental and medical clinics, salons, law firms and any service business where a missed call means a lost job.
An AI Phone Receptionist You Can Trust
Like a good AI phone receptionist, it tells callers it’s an AI whenever they ask. It never invents prices or promises. When it doesn’t know, it takes the details so you can confirm.
When an AI Answering Service Is Not Enough
If a caller has an emergency that needs a person right now, or a complaint that needs care, the AI should take the details and you should call back fast. It handles the first contact, not every conversation. It answers incoming calls; outbound calling is not available yet.
Better With the Rest of zentroStack

What Can an AI Answering Service Handle?
Most calls to a service business are the same handful of questions. An AI answering service handles them well because the answers come from your own information:
- Opening hours and the areas you cover
- Which services you offer and what each one involves
- Prices you have published, such as a call-out fee or a standard clean
- How to book, and whether someone can come soon
- Where to send photos or documents
When a caller asks something the AI was not told, it does not guess. It takes their name, number and what they need, so your AI answering service never promises a price or a date you did not agree to.
How zentroVoice Answers a Call
Phone calls reach zentroVoice through a Twilio number, and calls from your website come straight from the visitor’s browser with no number to dial. The voice runs on OpenAI realtime speech, so replies sound natural and come quickly. Each call has a 10-minute limit and you set a daily call limit, so a busy day cannot run up a surprise bill.
When the AI has the caller’s name and a way to reach them, it saves the lead in zentroCRM straight away. If the call drops halfway, you still have the details you need to call back.
An AI Answering Service for Small Business, Trade by Trade
Plumbers and HVAC: urgent calls come at night and at weekends. The AI takes the address and the problem so you can decide who goes out first.
Electricians and handymen: you cannot pick up while working on a live circuit. The AI answers and writes down the job.
Cleaning companies: callers want to know if you cover their area and when you are free. The AI answers from your service list and takes the details.
Dental and medical clinics: reception is busy at the start of the day. The AI answers general questions and takes contact details for the team to call back.
Salons and law firms: the AI handles first enquiries politely, so new customers are never sent to voicemail.
Frequently Asked Questions
Can zentroVoice answer my existing business number?
Yes, you forward your existing business number to your zentroVoice number, so customers keep calling the number they know and the AI answers when you can’t pick up.
Will callers know they are talking to an AI?
Yes. If a caller asks, zentroVoice says plainly that it is an AI assistant. It never pretends to be a person, which keeps you on the right side of customer trust and local rules.
Is an AI answering service for small business worth it?
For most service businesses, yes, because one job saved from a missed call can cover the monthly cost. Compare the leads it captures with your missed-call log after the first month.
Can it make outbound calls?
Not yet. zentroVoice answers incoming calls today, on your phone number and on your website call button. You follow up the leads it captures from your CRM.
Does it work outside the US?
Yes, zentroVoice works for businesses worldwide, and phone number options depend on your country. The website call button works anywhere your website loads. Contact us to check local number availability.
How much does an AI answering service cost?
zentroVoice plans start at $25 a month on a yearly plan ($31 month to month) for 100 AI call minutes, and go up to $280 a month for 1,200 minutes. Every plan includes your own US phone number, and extra minutes cost $0.25 each. You can try it first with a 60-day free trial: 60 minutes, no card needed. See the plans.
Can I hear zentroVoice before I sign up?
Yes. Use the call button on our website to talk to the AI from your browser, ask it the questions your customers ask, and hear how it answers and takes details.
What happens when a caller wants a real person?
The AI says that is fine, takes their name, number and what they need, and saves it in your CRM so someone can call them back quickly.
Which voices can I choose?
You can choose from 10 voices, male, female and neutral, and play each one in your settings before you decide which one answers your calls.
