You've decided you can't answer every call yourself. Maybe it's the evenings, maybe it's the Monday morning rush, maybe it's that you're up a ladder or in a treatment room for most of the day. Hiring a full-time receptionist feels like too much, so you look at outsourcing, and three kinds of service come up: a live answering service, an outsourced call centre, and an AI answering service.
This page sets out the AI answering service vs call center choice properly, with the live answering service in the middle, because it's often the real alternative for a small business. Prices are taken from providers' own pricing pages as of October 2026, and labour figures from the US Bureau of Labor Statistics and the UK Office for National Statistics. Klugon, which makes this site, is used as one example of an AI answering service. Others exist, and the best AI receptionist roundup compares several.
The short verdict
Use an outsourced call centre if you have high call volumes, need agents working from detailed scripts or systems, run outbound campaigns, or need formal reporting and service levels. Call centres are built for scale and process, and they usually quote rather than publish prices.
Use a live answering service if every caller should speak to a person, if calls often need to be put through to you, or if you need messages taken with human judgement. Pricing is usually per minute and adds up quickly at volume.
Use an AI answering service if most of your calls are routine (hours, prices, availability, bookings, new enquiries), you want every hour covered, and you'd rather pay a flat monthly fee than per minute. It can't transfer calls on every platform (Klugon can't), and it doesn't replace human judgement on difficult calls.
Combine them if your calls split cleanly: people for the hours and call types that need them, AI for the rest.
The three options in plain terms
Live answering service
A shared team of receptionists answers your calls with your business name, follows your instructions, takes messages, books appointments in your calendar and, on most services, transfers calls to you. You share the receptionists with many other businesses, so you pay only for the minutes used. Ruby, AnswerConnect, PATLive and Moneypenny are well-known examples. These services are aimed at small businesses and professional practices.
Outsourced call centre
A contact centre provides agents who handle calls for you, either shared across clients or dedicated to your account. They're usually used for larger volumes: customer service lines, order lines, technical help desks, sales campaigns. Agents work from scripts and often inside your own systems. Many also handle email, chat and outbound calls. Contracts tend to be bespoke, with setup, training and minimum volumes.
The line between the two is blurry. Many answering services describe themselves as call centres, and many call centres sell small-business answering. The practical difference is scale and customisation: call centres are built around your process; answering services are built around a standard service you configure.
AI answering service
Software answers your calls with an AI voice. It answers questions from information you give it, books appointments and captures caller details. Calls it can't handle are passed to your team, either by transferring the call (on some platforms) or by flagging it for a callback (on others, including Klugon). Pricing is usually a monthly plan with included minutes, per minute or per call. Our AI phone receptionist page explains how Klugon's version works.
AI answering service vs call center at a glance
Answering service and call centre figures are from the providers' own pages as of October 2026, linked in the pricing section. The AI column uses Klugon's pricing as one example.
| Criterion | Outsourced call centre | Live answering service | AI answering service (Klugon as an example) |
|---|---|---|---|
| Who answers | Trained agents, shared or dedicated | Shared live receptionists | AI voice agent |
| Price model | Usually quoted: per agent hour, per minute, per call or per outcome | Monthly bundles of minutes, overage per minute | Flat monthly plan with included voice minutes |
| Published entry price | Rarely published | $99/month for 50 minutes (PATLive) to $250/month for 50 minutes (Ruby) | $99/month for 1,000 minutes, plus $9/month per number |
| What's included | Scripted handling, often CRM work, reporting, email and chat | Answering, messages, scheduling, call transfer | Answers questions, books, captures leads, logs every call |
| Channels | Phone, often email, chat and social | Phone; live chat as separate plans on some | Phone and browser voice; WhatsApp, Instagram, Messenger and website chat as separate products |
| Booking | In your systems, if agents have access | In your online calendar | Into Klugon's built-in calendar, using your hours, services and staff |
| Handover to staff | Escalation paths, warm transfer | Live transfer to any number | Flags the conversation for your team with a note; no live transfer |
| Outbound calls | Commonly offered | Offered by some (PATLive sells outbound plans) | Not offered by Klugon |
| Setup | Discovery, scripting, training; weeks rather than days | Onboarding call or form, scripts | Self-serve; phone number added after the trial |
| Contract or trial | Usually a negotiated contract | Often month to month; some trials and guarantees | 7-day free trial (card required); monthly or yearly billing |
Pricing models compared
How a service charges shapes what it costs you far more than the headline price. Here are the models you'll meet.
Per minute (most answering services)
You buy a monthly bundle of minutes and pay extra for minutes over it. The small print matters:
- Rounding. Most round each call up to the next whole minute. A 61-second call costs two minutes.
- What counts. Some count hold time, message-taking and after-call work. Ruby's FAQ says it includes hold time and excludes talk time once a call is transferred to you.
- Overage. Overage rates are usually higher per minute than the bundle rate.
As of October 2026, published plans from three well-known US answering services:
Ruby (24/7 live answering included on every plan):
| Plan | Monthly | Receptionist minutes |
|---|---|---|
| Plan 1 | $250 | 50 |
| Plan 2 | $395 | 100 |
| Plan 3 | $720 | 200 |
| Plan 4 | $1,725 | 500 |
Ruby's pricing page doesn't publish its overage rate. Its FAQ says minutes are billed in 60-second increments, rounded up, and that receptionists can transfer calls to any number you choose. It offers a money-back guarantee to first-time users.
AnswerConnect (24/7 live answering):
| Plan | Monthly | Minutes | Each extra minute |
|---|---|---|---|
| Entry | $350, plus $49.99 setup | 200 | $2.50 |
| Growth | $395, no setup fee | 300 | $1.85 |
| Standard | $575, plus $49.99 setup | 400 | $1.85 |
| 550 | $795 | 550 | $1.85 |
| 1,200 | $1,625 | 1,200 | $1.85 |
| 5,000 | $6,650 | 5,000 | $1.75 |
AnswerConnect lists larger plans up to 100,000 minutes. It rounds each interaction up to the next minute, doesn't charge for the first 30 interactions under 30 seconds in a billing cycle, and says there's no contract.
PATLive (US-based, 24/7, no night or weekend fees):
| Plan | Monthly | Minutes | Each extra minute |
|---|---|---|---|
| Pay as you go | $49 | 0 | $2.99 |
| 50 | $99 | 50 | $2.29 |
| 200 | $349 | 200 | $1.99 |
| 500 | $759 | 500 | $1.79 |
| 1,000 | $1,499 | 1,000 | $1.69 |
| 5,000 | $6,899 | 5,000 | $1.49 |
PATLive offers a 14-day free trial, no contracts, and states that it doesn't use AI to answer calls. It also sells live outbound calling and live chat plans.
Not every service publishes prices. Moneypenny's pricing page, for example, asks you to get in touch for a quote.
Per agent hour (dedicated call centre agents)
A dedicated agent works only on your account for an agreed number of hours. You pay for those hours whether the phone rings or not. This gives you agents who know your business deeply and can work in your systems, but it only makes sense with steady volume. Contact centres that offer this generally quote rather than publish rates, often with setup and training fees and a minimum commitment.
What sets the floor under those rates is the cost of the agent. The BLS Occupational Outlook Handbook puts the US median wage for customer service representatives at $21.53 an hour in 2025, across about 2.7 million jobs. In the UK, the ONS Annual Survey of Hours and Earnings, table 14 gives a median of £14.25 an hour excluding overtime for call and contact centre occupations in April 2025 (provisional), and £27,035 a year for full-time staff. A call centre's hourly price has to cover that wage, plus employer costs, supervision, quality checks, technology, premises and margin, so expect quotes well above the wage itself.
Per call
Some services, AI and human, charge per call regardless of length. It's predictable when calls are long and penalising when many are short. Our comparison with Smith.ai shows how per-call pricing works out in practice.
Per outcome
Some contact centres, mostly in sales, charge per booked appointment, per sale or per qualified lead. It aligns the incentive, but definitions matter: what counts as "qualified" is negotiated, not given.
Flat monthly plan with an allowance (many AI services)
You pay a fixed monthly fee for a large allowance of minutes, conversations or calls. Using Klugon as an example, as of October 2026:
| Klugon AI voice agent | Monthly | Yearly (per month) | Voice minutes a month | Phone numbers allowed |
|---|---|---|---|---|
| Starter | $99 | $79 | 1,000 | 1 |
| Business | $299 | $239 | 3,600 | 3 |
| Scale | $499 | $399 | 6,000 | unlimited |
Each phone number costs $9 a month. Extra voice minutes cost $15 per started 100 minutes. Slack and Zapier notifications, HubSpot, Zoho and Pipedrive connections, and Google, Outlook and Apple calendar connections need Business or higher; Salesforce needs Scale. Our AI receptionist cost guide compares this with other AI vendors' pricing.
A worked cost example
Say a home repair business gets 300 calls a month, averaging 2 minutes each: 600 minutes. Most are "can you come and look at…", "how much is…" and "when are you free?". Assume minutes are counted at the average with no rounding effect; in practice, rounding up each call pushes human answering bills higher.
| Option | How it's calculated | Monthly cost (as of October 2026) |
|---|---|---|
| Ruby | 500-minute plan at $1,725, plus 100 minutes at an unpublished overage rate | more than $1,725 |
| AnswerConnect | 550-minute plan at $795, plus 50 × $1.85 | $887.50 |
| PATLive | 500-minute plan at $759, plus 100 × $1.79 | $938 |
| Outsourced call centre | Quoted; a dedicated agent would be idle most of the hour at this volume | not published |
| Klugon voice Starter | $99 plan, plus $9 for one number; 600 minutes is within the 1,000 included | $108 |
At this volume, the AI option costs a fraction of the human ones. But look at what the money buys. Each of the live answering services will transfer a caller to you, and a person will judge whether "water coming through the ceiling" needs you now. Klugon will book a visit, capture the caller's details and flag the urgent call for your team, but it won't put the call through, and it won't ring you. Whether that difference is worth several hundred dollars a month is a question only your callers can answer.
The comparison changes with volume. At 50 short calls a month, a pay-as-you-go answering service may cost less than any AI plan. At 3,000 minutes a month, human answering runs into thousands of dollars while Klugon's Business plan covers 3,600 minutes for $299 plus numbers.
Quality: what callers get
Callers of a live answering service
A real person who answers in your business name, speaks naturally, copes with confusion and can tell when a call needs you. The limits are knowledge and continuity: shared receptionists handle many businesses, so they work from the instructions you've given and may not know your services in depth. A caller with a detailed question often gets "I'll take a message".
Callers of an outsourced call centre
Agents can be trained deeply on your business, especially dedicated agents. Quality depends heavily on the provider, the training budget and how well your scripts are written. Expect quality monitoring and reporting, often call recording, and service levels written into the contract.
Callers of an AI answering service
The AI answers from the same information every time and knows your services as well as the knowledge you've given it. Klugon's AI uses a knowledge base built from pasted text, uploaded documents and a scan of your website, and books directly into its calendar. Callers can interrupt it, and it stops talking. Its voices are natural-sounding but AI-generated, and some callers will notice. Klugon's default greeting doesn't say it's an AI; you can write one that does.
The AI's weaknesses are the human strengths: judgement, empathy with an upset caller, and handling the unexpected. It should hand those calls over, and you should test it with your awkward calls before trusting it. It isn't guaranteed never to get something wrong.
Records and follow-up
Call centres and answering services often send you messages by email, text or app, and many offer call recording; check each provider. Klugon logs every call in your inbox, but doesn't record calls, and transcripts may contain only the AI's side. It sends no email or text alerts; notifications go to Slack or Zapier on Business and up. If your process depends on a recording or an emailed message after every call, that's a point for the human services.
Scale and peaks
How each copes with a busy Monday
- Call centre: scales by staffing. A good provider forecasts your volume and rosters agents to it. Sudden spikes beyond the forecast mean queues, unless you pay for spare capacity.
- Answering service: a shared pool absorbs spikes across many clients. Your cost rises minute for minute.
- AI service: isn't tied to a roster in the same way, but every platform has technical limits. Klugon doesn't publish a concurrency figure, so ask any AI vendor how many simultaneous calls your plan supports before relying on it for peaks.
Seasonality
Businesses with seasonal peaks (heating engineers in the first cold snap, tax advisers in January, garden services in spring) face a trade-off. Call centres need notice to staff up. Answering services charge for every extra minute. An AI plan with a large allowance absorbs peaks, and Klugon bills extra voice minutes at $15 per started 100 if you go over.
Growth
As volume grows, per-minute pricing grows in a straight line. Call centres get cheaper per contact at scale but need contracts and management. AI plans step up in tiers.
Channels beyond the phone
Many customers would rather message than call. Contact centres commonly offer email, chat and social channels. Answering services increasingly sell live chat: as of October 2026, Ruby sells chat plans from $143 a month for 10 chats, and PATLive and AnswerConnect list live chat too. Klugon sells messaging as separate products: a WhatsApp AI chatbot with Instagram and Messenger in the social agent, and an AI chatbot for your website. All of them land in one inbox. If you need someone handling customer emails, that's a call centre or a person, not Klugon.
Compliance and sensitive calls
If you handle health information in the US, you need a service that will sign a Business Associate Agreement under HIPAA. Some answering services and call centres offer this; ask before you sign. Klugon isn't HIPAA compliant and doesn't sign BAAs, and has no SOC 2 or ISO 27001 certification. It is operated by a German company under the GDPR, with transfers to providers covered by standard contractual clauses, as listed in its privacy policy.
For clinics, law firms and financial advisers, the rule is the same whichever service you use: the person or AI answering must not give clinical triage, legal advice or regulated financial advice. A human service can escalate in real time. An AI should be set up to hand those calls to a person.
When to use each
Choose an outsourced call centre when
- you handle hundreds of calls a day or more;
- agents need to work inside your systems (order lookups, account changes, technical support);
- you need outbound campaigns, email handling or formal service levels;
- you can commit to volumes and a contract.
Choose a live answering service when
- every caller should reach a person;
- calls often need putting through to you or a colleague;
- your volume is low to moderate and calls are short;
- you need someone to judge which calls are urgent.
Choose an AI answering service when
- most calls are routine questions and bookings;
- many calls come in evenings, weekends or at peaks;
- per-minute bills from a human service have become hard to justify;
- you also want WhatsApp, Instagram, Messenger or website chat answered.
Combine them when
- Days and nights split: a live answering service in office hours, AI after hours, set up with your carrier's time-based forwarding. Our after-hours answering service page covers this pattern.
- Phone and messaging split: a human service on the phone and AI on messaging channels.
- Overflow: your own staff first, AI when nobody picks up within a few rings.
With Klugon, a call can't be passed on from the AI to a human service mid-call, so split calls by time or by forwarding rule, not by handing over during the conversation.
Where a call centre or answering service is the better choice
- Live call transfer. Ruby, AnswerConnect and most human services put calls through. Klugon only flags the conversation for a callback.
- Outbound calls. Call centres and some answering services, such as PATLive, make outbound calls. Klugon doesn't.
- Texts and reminders. Some human services send you messages by text, and some make outbound or reminder calls for you. Klugon sends no SMS, reminders or confirmations.
- Call recordings. Common at call centres. Klugon doesn't record calls.
- Judgement and empathy. Complaints, distress, confusion.
- Working inside your systems. Dedicated call centre agents can process orders and update accounts.
- HIPAA. If you need a BAA, use a service that signs one.
- Very low volume. A pay-as-you-go answering service may cost less than any AI plan if you get a handful of calls a month.
Where an AI answering service is the better choice
- Cost at moderate volume. Klugon's 1,000 included minutes for $99 a month compare with $759 for 500 minutes on PATLive and $1,725 for 500 on Ruby, as of October 2026.
- Every hour covered for the same price. No night, weekend or bank holiday premiums.
- Consistent answers. From your own information, every time.
- Direct booking. Into a calendar that knows your service lengths and staff.
- Languages. Klugon answers in English, German, French, Spanish, Italian, Portuguese, Dutch, Japanese and Arabic.
- Messaging in the same inbox. WhatsApp, Instagram, Messenger and website chat alongside calls, with the separate products.
- No contract. Monthly billing, or yearly at about 20% less.
Switching steps: from an answering service or call centre to an AI service
- Export a month of call data. Your current provider's reports or message log show call reasons, times and lengths.
- Sort the calls. Routine (hours, prices, bookings) versus needs a person (transfers, complaints, urgent work).
- Write down what your current receptionists or agents use. Scripts, FAQs, prices, policies. That becomes the AI's knowledge.
- Set up and test. With Klugon, sign up, add services, opening hours and knowledge, choose a voice and write a greeting. Test it in the browser during the 7-day trial (card required). A phone number can be added once the trial ends.
- Decide what gets handed over and who calls back. Connect Slack or Zapier on Business and up so flagged calls reach someone quickly.
- Run both in parallel. Point after-hours calls to the AI first, using your carrier's forwarding, while your current service keeps daytime calls. Our guide to keeping your number with call forwarding explains how.
- Compare a month of results. Calls answered, bookings made, calls flagged, and what callers said.
- Move more hours, or don't. Check your current provider's notice terms before cancelling.

Frequently asked questions
What is the difference between an answering service and a call centre?
An answering service is a shared team of receptionists answering calls for many small businesses, usually billed per minute. A call centre handles larger volumes, often with dedicated agents working from your scripts and systems, usually on a quoted contract. Many providers sell both.
Is an AI answering service cheaper than a call centre?
At small and moderate volumes, almost always. Klugon's voice Starter plan is $99 a month for 1,000 minutes plus $9 per number, while live answering services charge $99 to $250 for 50 minutes on their entry plans, as of October 2026. Call centres rarely publish prices, and dedicated agents are paid by the hour whether calls arrive or not.
Can an AI answering service transfer calls?
Some can. Klugon can't. It saves the caller's details and a note, flags the conversation for your team and, on Business and up, posts it to Slack or Zapier for a callback.
Do AI answering services work 24/7?
Klugon answers whenever the plan is live and calls are routed to it, including nights, weekends and bank holidays, at no extra charge. Many human answering services also cover 24/7; PATLive, AnswerConnect and Ruby include it in their plans.
Will callers know they're talking to an AI?
Some will. Klugon's voices are natural-sounding but AI-generated, and its default greeting doesn't say it's an AI. You can write your own greeting that tells callers.
Can I use an AI answering service and a live answering service together?
Yes, by splitting calls by time or forwarding rule: for example, a live service in office hours and AI after hours. With Klugon, the AI can't hand a live call to the other service mid-conversation.
Do AI answering services make outbound calls?
Some do. Klugon doesn't make outbound calls or send texts. If you need callbacks made for you, use a human service or call back yourself from the flagged conversations.
Which is better for a medical practice?
If you need HIPAA compliance and a Business Associate Agreement, use a service that signs one; Klugon doesn't. In any case, the answering service, human or AI, mustn't triage symptoms. An AI can handle bookings and practical questions and should hand clinical calls to a person.
If routine calls make up most of your phone traffic, an AI answering service for small business is worth testing against what you pay a human service today. If they don't, keep the people.
