Phone answering services: what they do and cost
A phone answering service takes calls for a business when nobody there can pick up. In the classic form, people in a service office answer with the company name, take down the request and pass it on. The newer form is the AI answering service: instead of writing a note, a voice assistant completes the request during the call, booking the appointment rather than recording that somebody wants one. Both solve the same problem of missed calls, but they stop at different points.

How an answering service works
Four steps that look the same at every provider, whether a person or an AI is on the line.
Forward the number
Your existing number is diverted, either always or only when nobody in the office picks up. Your phone provider stays the same.
Answer the call
The service answers with your company name. Callers do not notice they did not reach your own front desk.
Capture the request
Name, callback number and reason are recorded. A classic service writes it down; an AI service completes what it can complete.
Hand it over
The note arrives by email, SMS or in your CRM. Anything urgent is put through immediately, by rules you set in advance.
Answering service, dedicated secretary and AI phone agent
Three names for the same job, differing in one thing: how much work is left once the call ends.
| Classic answering service | Dedicated secretary | AI phone agent | |
|---|---|---|---|
| Who answers | Staff in a shared service office | One person dedicated to you | A voice agent on your number |
| Captures the request | |||
| Books into your calendar | sometimes | ||
| Available around the clock | sometimes | ||
| Any number of calls at once | |||
| Knows the trade vocabulary | sometimes | ||
| Cost rises with call volume |
“Sometimes” means it depends on the provider or the package. A dedicated secretary is usually one person with working hours, but one who knows your business well. That is the honest strength of the human option: somebody trained on your business makes judgement calls that no system should be making.
What an answering service costs
Three pricing models exist. Which one is cheaper depends almost entirely on one number: how many calls actually arrive each month.
Base fee plus price per call
A monthly fee covers a quota of calls and anything beyond it is billed individually. Predictable at steady volume, expensive in a rush.
Price per seat
You pay for the person, not the conversation. Usual for a dedicated secretary. A quiet month costs the same as a busy one.
Billed per conversation minute
You pay for what was actually spoken. This is how elunos.ai bills: a free tier, no per-seat fee, and a calculator on the pricing page.
Other providers' prices are deliberately absent here. They are rarely published, they change, and a wrong figure in a comparison is a legal problem rather than a typo. Ask them directly, and do the maths with your real call volume instead of the example in the quote.
Answering services by trade
Three trades search for this specifically, and all three are doing the same sum: what does a missed call cost?
For medical practices
The front desk cannot be on the phone and with the patient in front of them at once. What matters here is that urgent calls are recognised and passed on immediately rather than ending up in a note.
Answering services for practicesFor law firms
A new client calls once. If they reach voicemail, they call the next firm. What matters is a proper first intake with the facts, not just a callback slip.
Answering services for law firmsFor trades and crafts
Nobody answers the phone on site, and emergency calls come in the evening. What matters is that a job enquiry is captured in full, address and trade included.
Answering services for tradesCommon questions about answering services
An answering service is an office taking calls for many businesses at once. A dedicated secretary is narrower: usually one person or a small team working only for you, who knows your processes and is therefore allowed to decide more. Price follows that closeness, and so does availability, because a dedicated person has working hours.
It depends on the model and on call volume. Common are a base fee with a quota, a per-seat price, or billing per conversation minute. Do the maths with your real volume: with base-fee models it is the calls above the quota that decide whether it stays cheap. elunos.ai bills per conversation minute, with a free tier and no per-seat fee.
For recurring requests yes, and it is faster there: booking, answering, capturing a request in a structured form, around the clock and on any number of calls at once. For anything needing judgement, no. A trained person spots the unusual case, and that is what they should stay responsible for. The sensible split is that the AI removes the volume and the team gets the calls that actually need them.
They are told, and that is deliberate. Disclosure is expected for voice systems under the EU AI Act and is fair regardless. What matters to a caller is not human or machine, but whether their request is finished on the first call instead of after three callbacks.
No. The service is published on your existing number by call forwarding. Your phone provider stays the same and customers keep dialling the number they know. You can limit the forwarding to the hours when nobody in the office picks up.
That depends on the provider, not the technology. Three questions decide it: where calls are processed and stored, whether there is a proper data processing agreement, and whether caller data leaves the EU. For elunos.ai the answers are: Frankfurt, yes, and no.
