Short answer: Voicemail is cheapest but gives the caller no live answer. An IVR menu routes calls but cannot hold a conversation. A human answering service handles odd and emotional calls best and costs the most per minute. An AI receptionist sits between: it talks, books and takes messages at a fraction of human per-minute prices, but it struggles with unusual requests. As of October 2026, entry prices on public vendor pages run from about $19 per user for a phone line with voicemail to $250 per month for a human service (verify on each site).
What each option actually is
- Voicemail: the caller leaves a recording and you listen later. It ships with nearly every business phone line.
- IVR (interactive voice response, or auto attendant): a menu such as 'press 1 for sales' that routes the call. It follows a fixed script and cannot answer questions it was not built for.
- Answering service or virtual receptionist: real people, usually in a call center, who answer in your business name, take messages and sometimes book appointments or transfer.
- AI receptionist: software that holds a spoken conversation, answers from information you give it, books or takes a message, and can hand off to a person.

What a minute costs
Per-minute comparisons are only possible where a page states included minutes. Dividing price by included minutes is our arithmetic (Lead Friendly analysis of the vendor pages above), and it ignores overage, setup and what is counted as a minute.
On that basis, as of October 2026, Ruby's Startup plan works out to $5.00 per included minute ($250 for 50 minutes) and its largest listed plan to $3.45 ($1,725 for 500). Dialzara's inbound plans work out to $0.48 per included minute on Lite ($29 for 60) and $0.35 on Elite ($349 for 1,000). Verify both on the vendors' sites.
Lead Friendly analysis: monthly plan price divided by included minutes. Excludes overage, taxes and setup. Verify on each vendor's site.

Scorecard: how we rate the four options
| Criterion | Voicemail | IVR menu | Answering service | AI receptionist |
|---|---|---|---|---|
| Answers any hour, many callers at once | ||||
| Handles unusual or emotional calls | ||||
| Captures details into your system | ||||
| Low caller friction | ||||
| Cost at low call volume | ||||
| Cost at high call volume |
How we scored: Scores are the Lead Friendly team's judgments, not measurements. 5 is best on the criterion (for cost, cheapest). We weighed the published prices above, what each option does when a caller goes off script, and whether it writes details somewhere you can act on. We make an AI receptionist, so weigh our scores accordingly and adjust them for your trade.
Which one fits: a decision table
No option wins everywhere. The honest answer depends on how many calls you miss and what a missed call is worth.
| Your situation | Likely fit | Why |
|---|---|---|
| A few missed calls a week, mostly routine | Voicemail with a clear greeting, plus a text-back | Cheapest, and little is lost |
| Many calls that only need sorting by department | IVR menu | Routing is the whole job |
| Steady volume of repeat questions and bookings, evenings and weekends missed | AI receptionist | Handles routine calls at any hour at lower per-minute prices |
| Few calls, but each is high value or emotional (legal, medical, funeral) | Human answering service | Judgment and tone matter more than price |
| Urgent trades such as plumbing, HVAC, locksmith | AI first with live transfer to your team, or a human service | Callers want a person quickly; the fallback matters more than the greeting |
| Medical office handling patient details | Vendor that signs a BAA | HIPAA applies; check the agreement before you go live |
Where AI is the wrong choice
- Callers who are distressed, grieving or frightened and need a person's tone.
- Calls where the right answer depends on judgment you have not written down.
- A line with so few calls that a monthly plan costs more than the calls are worth.
- Any setup with no route to a human: a caller who asks for a person should reach one or leave a message that someone reads the same day.
Frequently asked questions
Is an AI receptionist cheaper than an answering service?
On the public pages we opened, as of October 2026, yes: the AI plans we compared cost less per included minute than the human services. Plans count usage differently (minutes, calls), so compare using your own call volume and verify current prices.
What is the difference between an IVR and an AI receptionist?
An IVR presents a fixed menu and routes the call. An AI receptionist holds a conversation, answers from information you give it and can book or take a message. The IVR is predictable; the AI is more flexible and can misunderstand.
Is voicemail enough for a small business?
It can be if you get few calls and call back quickly. The cost is callers who hang up without leaving a message, which voicemail cannot recover. A missed-call text-back is a low-cost addition.
Can I use more than one of these together?
Yes. A common setup is a short menu or AI greeting first, a live transfer to your team during business hours, and a human service or message-taking for overflow.
