Answering service for businesses, run by AI
An answering service picks up your business phone when nobody on your team can. Asyntai is a digital answering service: an AI voice agent that answers on your line, gives callers real answers from your website and documents, puts them through to you during your hours, and emails you the rest with a callback number the caller confirmed.
Three kinds of answering service, and where each one fits
An answering service is anyone, or anything, that takes your business calls when you cannot. If you search for phone service answering, you meet three main forms, and you can mix them by the hour of the day.
Voicemail: the caller does the work
The phone rings out, your greeting plays, and the caller decides whether to leave a message after the beep. Nothing more happens until you listen and ring back. It is usually part of your phone plan and needs no setup.
“Hi, it's about my order. Call me back when you get this.”
A human answering service: operators at the service
You forward calls to a company whose operators pick up in your business name. They work from the instructions you give the service and pass messages on in the format you agree. Billing is usually by the minute or per call.
“Could you let them know I called about the banner?”
An AI answering service: answers from your content
A voice agent picks up, says it is an AI assistant and then gives your greeting. It answers from your website, documents and AI Instructions, transfers callers to you during your hours, and turns the rest into callback requests.
“How long do 500 business cards take?”
Cover part of the day, or all of it
An answering service does not have to take every call. Call forwarding on your line decides which calls go on: the ones you miss, the ones that meet a busy line, the evening and weekend ones, or every call.
“I tried at lunchtime and nobody picked up.”
Your business information becomes the call script
A digital answering service is only as useful as what it knows about you. Asyntai takes its answers from three sources that you control, and uses them on every call.
- Your websiteAsyntai reads it page by page: products, services, opening hours, delivery areas, contact details. When a page changes, have Asyntai read that page again.
- Documents with the detailsA price sheet, turnaround times, a returns policy, a guide for new clients. Upload PDF files or paste the text. A changed document is used from the next call.
- AI Instructions in plain EnglishWhich jobs need a quote first, when to offer a transfer, what to say about rush work. Write them once, and each call follows them.
Every call ends in one of three places
You judge an answering service by what is left when the caller hangs up. With Asyntai, the caller has an answer, has spoken to you, or has left a request with a number you can rely on.
- The question is settled on the callPrices, turnaround, opening times, what to bring: answered from your content, so nobody has to ring back.
- The caller reaches a personIn your Escalate to Human hours, the call goes to the line's transfer number, and your phone shows the caller's own number.
- The request waits in your inboxA name and a callback number that the agent repeated digit by digit and the caller confirmed, sent to your escalation email.
Move your phone over to the answering service
The agent answers a number in your own Twilio account, and Twilio bills you for that number and its call minutes. Keep the number your customers know and forward calls to it, or make the Twilio number your business line.
- Open an Asyntai account and enter your website. The pages are read in a few minutes. Add your price sheet and any guides as documents.
- Write a greeting on the Voice Agent page and make a free test call in the browser. Ask what your customers ask you every week.
- Connect Twilio on the Phone Calls page with your Account SID and Auth Token, then press Import next to the number to be answered.
- Choose a transfer number and set hours under Escalation. Then turn on forwarding from your current line, and call your own number to hear the result.
The same phone call, handled three ways
One caller with a question about prices, at a moment when nobody can pick up. This is what each kind of answering service does with that call.
| Point | Voicemail | Human answering service | Asyntai AI answering service |
|---|---|---|---|
| When the call is picked up | After your phone rings out | When the forwarded call reaches operators at the service | When the forwarded call reaches your Twilio number; the agent replies within a second or two of the caller speaking |
| The price question | Waits in your mailbox until you ring back | Handled as your instructions to the service say | Answered from your price sheet or website, if the price is there; otherwise a callback request |
| A caller who wants you now | Has to try again later | Depends on the service | Transferred to your number during your Escalate to Human hours |
| The note you get | A spoken message, if the caller leaves one | A message, in the format the service uses | A callback request by email with a confirmed number, plus the full transcript |
| Updating what callers hear | Change your greeting | Send the change to the service | Edit a document or the AI Instructions; the next call uses them |
| Two callers at once | Depends on your phone line | Depends on the service | 2 calls at the same time on Standard, 5 on Pro |
| Billing | Usually part of your phone plan | Usually by the minute or per call | A monthly plan with included voice minutes; Twilio bills the number and call minutes |
Human answering services differ from one provider to the next, so check the terms of any service you compare. Twilio rates are on the Twilio voice pricing page.

Answering service: questions to ask before you choose
The points that decide which kind of answering service suits a business, and how the AI option works.
What is an answering service?
It is a service that picks up your business calls when you and your staff cannot. The caller is greeted in your business name, and the reason for the call reaches you. It can be voicemail, operators at an outside company, or an AI voice agent such as Asyntai.
What does digital answering service mean?
It usually means that software, not a person, picks up the call. With Asyntai the software is an AI voice agent: it holds a spoken conversation, answers from your content, transfers callers during your hours, and sends callback requests by email.
How is an AI answering service different from an answering machine?
An answering machine plays a greeting and waits for a message. The AI agent talks with the caller. It answers the question from your website and documents, puts the caller through to you in your hours, and, when a callback is needed, repeats the number to the caller to confirm it.
Will callers know that the answering service is an AI?
Yes. Each call starts with the agent saying that it is an AI assistant, then your greeting follows. Callers who want a person can say so at any point in the conversation.
Can my business keep its phone number?
Yes. The agent answers a number in your own Twilio account, and your current line forwards calls to it. The call forwarding answering service page explains each forwarding rule. You can also publish the Twilio number as your main line.
Which of my calls should go to the answering service?
That is your choice, and you can change it later. Typical examples are calls you do not pick up, calls that meet a busy line, calls outside your opening hours, or all calls. Your escalation hours then decide whether a caller who asks for a person is transferred or leaves a callback request.
How is an answering service for businesses billed with Asyntai?
As a monthly plan. Standard is $139 a month with 200 voice minutes, and Pro is $449 a month with 1,500 voice minutes. Each answer on a call counts as one AI reply on the plan. Twilio bills your number and call minutes on your own Twilio account.
What does a caller hear if every line is in use?
That the lines are busy, and a request to call again in a few minutes. Standard answers 2 calls at the same time and Pro answers 5. When the month's voice minutes are used up, calls are declined with a short message until the minutes reset.
Can website visitors talk to the same agent?
Yes. Switch on the voice button on the Voice Agent page, and visitors can talk to the agent from your website chat instead of typing. It uses the same knowledge and the same voice minutes, and the transcript goes into the chat.
Answering services in plain terms: what you are buying
An answering service is a simple promise: when your phone rings and nobody in the business can take it, the call still gets picked up. The caller is greeted in your business name, the reason for the call is captured, and you find out about it. Behind that promise sit very different products. They differ in what the caller hears, in what reaches you afterward, and in how the bill is worked out. This guide sets out the options an owner meets when shopping for an answering service for businesses, and shows where Asyntai, an AI answering service, fits among them.
The cheapest option is the one built into almost every phone line: voicemail. It needs no contract and no setup beyond a greeting. It also hands all of the effort to the caller. They must decide to leave a message, say their number clearly, and then wait for you. Someone who only wanted your opening hours or a rough price gets neither. The message you play back that evening is only as complete as the caller made it. For a business with a few calls a week, voicemail may be all it needs. When any call could be a new order, it leaves a lot to chance.
The traditional step up is a human answering service. You forward your calls to a company whose operators answer for a number of client businesses. You give the service instructions about your business, the operators greet callers in your name, and messages reach you in the format the service uses. Billing is usually by the minute or per call, and the details depend on the provider. When you compare providers, ask what an operator will tell a caller, how messages reach you and how fast, how a change to your instructions is made, and how the invoice is calculated. The answering service cost page explains the pricing models you will meet on those invoices.
The newer option is an AI answering service, also called a digital answering service. Here a voice agent takes the call. With Asyntai, the agent opens by saying that it is an AI assistant and then speaks the greeting you wrote. After that it is a normal conversation: the caller hears a reply within a second or two and can cut in at any point, as with a person. The agent answers from your website, which Asyntai reads page by page, from documents you upload, such as a price sheet or a returns policy, and from AI Instructions you write in plain English. Prices and policies come only from that material. When a question goes past it, the agent offers to take a callback request.
Picture a print and sign shop on a busy Saturday, with the studio team at the presses. At ten, a caller asks how long 500 business cards take. The price sheet says three working days, so the agent gives that answer and the price. At eleven, someone wants lettering on a delivery van. The shop's rule says every vehicle is measured first, so the agent takes a callback request for the sign team. At noon, a customer asks to talk about a proof, and the agent puts the call through to the studio phone. In the evening, a club secretary asks whether a banner can be ready for next weekend and gives a phone number, which is saved as a lead. Four callers, and each one leaves with something.
The handover to your team is where an answering service shows its quality. In the hours you set for Escalate to Human, a caller who asks for a person is transferred to the transfer number of the line they called, such as the office phone or a mobile, and that phone shows the caller's own number. If nobody picks up within 20 seconds, or the line is busy, the caller returns to the agent, which apologizes and takes a callback request. Outside those hours, a request for a person becomes a callback request straight away. The agent asks for the caller's name and the number to ring back, repeats the number one digit at a time, and waits until the caller confirms it. The request goes to your escalation email, and the full transcript of the call is stored in your dashboard.
Deciding which calls the service takes is done on your phone line, not in Asyntai. The agent answers a number in your own Twilio account. Your current provider can forward calls to that number when you do not answer, when the line is busy, at set times, or for every call. You can also print the Twilio number as your business line and let the agent answer first. If the business phone is your own cell phone, the setup works the same way, with one setting to get right, which the mobile answering service page in the list above explains.
Cost and capacity are easy to read off the plans. Phone calls come with the Standard plan, $139 a month or $125 a month billed annually, which includes 200 voice minutes and 2 calls at the same time, and with the Pro plan, $449 a month or $404 billed annually, which includes 1,500 voice minutes and 5 calls at the same time. Each answer the agent gives counts as one AI reply on the plan, the same as in the website chat. Twilio bills the number and the call minutes on your account. When every line is in use, a new caller hears that the lines are busy and is asked to try again in a few minutes. When the month's minutes are used up, calls are declined with a short message until the minutes reset.
The fastest way to judge an AI answering service is to hear it with your own material. Create an Asyntai account, add your website and a document or two, write a greeting, and make a free test call in your browser. Ask the questions your customers ask, ask for a price you never give on the phone, and ask for a person. When the answers sound like your business, connect Twilio and forward one kind of call first, for example the evening calls. Read the transcripts for a week, then widen the forwarding. The voice agent guide covers every setting, and the industry pages above show the same service applied to calls in your field.
