The short answer
If most of your calls are routine (a booking, a quote request, a question about hours), an AI receptionist handles them and finishes the job on the call. If your calls are often emotional, complicated or high stakes, a live answering service gives you human judgment, and you pay for it by the minute or by the call.
The choice matters because answering is still the weak spot for a lot of businesses. In Invoca's 2026 study of calls to business services companies, only a little over half of callers reached a person.
Both options fix the unanswered call. They fix it in different ways, and that is what the rest of this guide is about.
What happens to one late call
Take one ordinary call: someone rings after closing, wants an appointment this week, and will call the next business if nobody helps. Here is how it usually goes with each option, step by step.
| Step | Live answering service | AI receptionist |
|---|---|---|
| Pickup | A trained agent answers with your greeting and your script. | Software answers with your greeting, any hour, with the same script every time. |
| The ask | The agent listens and adapts to the caller's tone. | It follows the questions you set, and is only as good as that script. |
| Booking | Possible when the service can see your calendar. Some providers charge it as an add-on per call. | Usually the main job: it checks open times and books on the call. |
| Confirmation | Often a message to you, and you confirm with the caller later. | A text to the caller as the call ends, if the system is set up for it. |
| Hard calls | A person can calm an upset caller and use judgment. | It should take a message and hand off to a person, never improvise. |
| What you see | Messages in an app, by email or by text. | A summary per call, plus the booking already in your calendar. |
The biggest gap is the last mile. Many answering services take a message and leave the booking for you. An AI receptionist that is wired into your calendar ends the call with the slot taken and the text sent. If the caller still has to wait for you to call back, you've only moved the voicemail somewhere friendlier.
How each one charges
Here is the part most comparisons skip. The two options don't just cost different amounts, they count different things. These are the entry plans as listed on each provider's own pricing page:
| Provider | Who answers | Billed by | Entry plan as listed |
|---|---|---|---|
| Ruby | People | Receptionist minutes | $250 a month for 50 minutes |
| Smith.ai | People (human-first plans) | Calls | $300 a month for 30 calls, $11.50 per call over |
| Talkroute | AI | AI minutes | $59 a month for 100 AI minutes, $0.35 per additional minute |
| Goodcall | AI | Unique customers | $79 a month per agent for 100 unique customers, $0.50 per customer after |
So the cheapest plan on paper depends on your calls, not on the sticker. A business with short calls does well on minutes. A business with long intake calls may do better paying per call. A business where the same customers call again and again may do best paying per unique caller.
What actually moves the bill
- Call length. On a minutes plan, a caller who talks for a while costs you more. Smith.ai's pricing page makes this point for billing by the call: you wouldn't rush a client off the phone, and they don't either.
- Spam and wrong numbers. Smith.ai says it doesn't charge for spam or unsolicited sales calls, as long as your forwarded lines pass caller ID. Ask every provider how it treats robocalls, because on some plans they eat your allowance.
- Add-ons. Smith.ai lists booking appointments at $1.50 per call on top of the plan, and call recording and transcription at $0.25. Ruby says its plans differ only by receptionist minutes, with optional features like scheduling and bilingual answering included.
- Nights and weekends. Smith.ai says calls at 2 pm and 2 am cost the same, and Ruby includes coverage after hours, on weekends and on holidays. Some services charge more for those hours, so ask.
- Language. Talkroute adds $0.15 per AI multilingual minute on its Starter plan. Smith.ai lists a dedicated Spanish line at $1.00 per call.
Where a person still wins
AI receptionists are good at the predictable middle of your calls. People are still better at the edges:
- Upset callers. Someone angry about a bill or a botched job wants to feel heard. A trained agent can do that. Software should hand that call off.
- Calls that need judgment. A clinic caller describing a reaction, a tenant with a leak, a client in legal trouble. The script should route these to a person, not answer them.
- Unusual requests. If half your calls don't fit any pattern, there's nothing stable to script.
- Callers who refuse software. Some people hang up the moment they hear a machine. If your customers skew that way, a person on the line is worth the minutes.
A lot of businesses end up with both: AI takes the routine calls and the night shift, and anything flagged as urgent or emotional goes to a person. Ruby, for example, now offers optional AI enhancements inside its live plans, which tells you where the market is heading.
Decide with one week of your own calls
You don't need a sales call to pick. You need one week of your call log. Write down every call that came in, then sort it with these five questions:
- Was it a booking, a quote or a simple question? Count these. They are the calls AI handles well.
- Was it urgent, emotional or clinical? Count these too. They need a person, either you or a live service.
- When did it come in? Mark the ones after hours and on weekends. That's the gap you're actually paying to close.
- How long did it last? If most calls are short, a minutes plan suits you. If they're long, look at plans billed by the call.
- Was it spam or a repeat caller? That tells you whether billing by unique customer or a spam-free policy saves you money.
Then use a simple rule. If the routine calls clearly outnumber the hard ones, start with an AI receptionist and route the hard calls to your phone. If the hard calls are a big share, use a live service, or a hybrid where a person handles anything the AI flags. Either way, take the week's totals to each provider's pricing page and price your own month, not the average one in a sales deck.
Where Cinemora fits
Cinemora is one remote studio for video editing, AI video, websites and AI automations. Ava, our AI receptionist, answers every call day and night, books it and texts the confirmation. We sell her as one package with your website's booking flow, so the phone and the site fill the same calendar, and we tune her script every month from the calls that came in.
Like everything we do, it starts free: we'll map the automation for your business before you pay anything. If you'd rather hear her first, there's a film of her taking a late call on our automations page.
Questions
Is an AI receptionist cheaper than an answering service?
Often, but compare your own month. The live plans listed here start at $250 a month for 50 minutes (Ruby) and $300 a month for 30 calls (Smith.ai human-first). The AI plans start at $59 a month for 100 AI minutes (Talkroute) and $79 a month per agent for 100 unique customers (Goodcall). Count your calls first, then price them.
Can an AI receptionist book appointments?
Yes, when it's connected to your calendar. That's usually its main job: it checks open times, books on the call and can text a confirmation. Some live services can book too, sometimes as a paid add-on per call.
What calls should still go to a person?
Upset callers, urgent or clinical calls, legal or billing disputes, and anything that doesn't fit a script. A good AI receptionist takes a message and hands these off instead of guessing.
Do answering services charge for spam calls?
It depends on the provider. Smith.ai says it doesn't charge for spam or unsolicited sales calls when your lines pass caller ID. Ask each provider before you sign.
