AI answering services, compared on the handoff
We lead on the handoff being configurable and priced. Transfer rules by job type and hour sit on our $49 Starter, booking comes with it, and the rate after 200 calls is published. You decide where a call goes when the assistant hands over, and which second number it tries next.
What separates these products is what happens when the assistant cannot help. Smith.ai sends that call to a human team it employs. Ruby, Abby Connect and AnswerConnect are human services with AI attached. GreetKeeper transfers to your team, tries a second number, or texts the on-call person with the caller's details.
The useful framing is how much the assistant handles and how cleanly it hands over the rest. Every GreetKeeper handoff arrives with a transcript and a short summary, so nobody asks the caller to start again.
On price, Dialzara at $29 and Rosie at $49 anchor the bottom, Smith.ai's Pro plan sits at $150 with people behind it, and Ruby starts at $250 for 50 minutes of human answering.
For a business whose main need is that nothing goes unanswered and everything reaches the right person, the deciding factors are transfer rules and the overage rate rather than the voice.
How this was put together
Compared in September 2026 on handoff behavior and published economics, by the team behind one of the entries.
What we compared
- What happens when the assistant cannot handle the call, in each product's own terms.
- Whether live transfer is available at the entry price.
- The billing unit and the published overage rate.
- Whether booking is included or gated to a higher tier.
The shortlist at a glance
Billing unit first, because it decides more of the final bill than the headline price does.
| Charges by | Entry plan | After the allowance | |
|---|---|---|---|
| GreetKeeper | per answered call | $49/mo for 200 answered calls | $0.45 a call on Starter, published |
| Smith.ai | per call | Free tier at $0 for 25 calls, then $3.00 a call | Published, and the per-call rate falls as the tier rises |
| Goodcall | per unique caller | Starter $79/mo ($66 annual) for 100 unique customers | $0.50 per additional unique customer, published |
| Abby Connect | per minute (half-rate AI) | Starter $165/mo for 50 Abby Minutes | Not published; one Abby Minute buys two minutes of AI handling |
| Rosie | per minute | Professional $49/mo for 250 minutes | Not published |
| Dialzara | per minute | Business Lite $29/mo for 60 minutes | Published on every tier, from $0.48 a minute down to $0.35 |

Read from each vendor's own pricing page in September 2026.
GreetKeeper
Transfer and booking at the entry price, with the rate after the allowance published.
Worth it for: A business that wants transfer rules by job type and hour, booking included at $49, and the cost of a busy month knowable in advance.
Charges per answered call. Entry plan $49/mo for 200 answered calls. After the allowance: $0.45 a call on Starter, published.
Smith.ai
The only entry here where the fallback is a person the vendor employs.
Worth it for: A business whose worst outcome is a call nobody could help with, where a trained human catching it is worth more than the price difference.
Not for: Anyone priced out at $150 a month for Pro, or anyone whose calls almost never need a person, where the human team is capacity you pay for and rarely use.
Charges per call. Entry plan Free tier at $0 for 25 calls, then $3.00 a call. After the allowance: Published, and the per-call rate falls as the tier rises.
Goodcall
Uncapped minutes and unique-caller billing, which suits a long handoff conversation.
Worth it for: Businesses where calls run long and callers repeat, since neither costs extra.
Not for: Multi-number setups, where each phone number is a separately priced agent.
Charges per unique caller. Entry plan Starter $79/mo ($66 annual) for 100 unique customers. After the allowance: $0.50 per additional unique customer, published.
Abby Connect
One currency across human and AI, so changing the mix does not change the plan.
Worth it for: A business that wants to start mostly human and shift toward AI, or the reverse, without renegotiating anything.
Not for: Tight budgets, at $165 for 50 Abby Minutes, with no published overage rate.
Charges per minute (half-rate AI). Entry plan Starter $165/mo for 50 Abby Minutes. After the allowance: Not published; one Abby Minute buys two minutes of AI handling.
Rosie
The cheapest entry, with transfer behind the second tier.
Worth it for: Message-taking on a budget where you will handle the callbacks yourself.
Not for: Anyone relying on live transfer, which starts at $149 rather than $49. The unpublished overage rate is the second issue.
Charges per minute. Entry plan Professional $49/mo for 250 minutes. After the allowance: Not published.
Dialzara
Cheap, with the overage rate published on every tier.
Worth it for: Low volume, where 60 minutes a month covers the calls you get.
Not for: Real volume. Sixty minutes on the entry plan is a handful of conversations.
Charges per minute. Entry plan Business Lite $29/mo for 60 minutes. After the allowance: Published on every tier, from $0.48 a minute down to $0.35.
AnswerConnect
Human answering around the clock, with the price behind a form.
Worth it for: A business wanting established 24/7 human cover, including weekends and holidays.
Not for: Comparing on published numbers, and short calls, since billing rounds up to the whole minute.
AnswerConnect does not publish its rates, so the cost is whatever the sales call produces.
When an answering service is not the fix
If most of your inbound is spam and robocalls, an answering service bills you to answer them. Look at a month of call logs before buying: plenty of businesses discover the phone volume problem they thought they had is mostly noise.
If your customers would rather text, buying voice software is solving a problem they do not have. Check where last month's inquiries actually came from.
And if some calls always need a person, list them in a transfer rule. The assistant answers first, captures the details and puts those callers straight through, so your team only takes the calls that need them.
Our own pricing, in full
Including the rate after the allowance, which is the number most of this list leaves off.
| Plan | Monthly | Calls included | After that |
|---|---|---|---|
| StarterFor a single location taking calls one line at a time. | $49 | 200 | $0.45 per call |
| ProfessionalBooking, routing and transfers included, not an add-on. | $149 | 750 | $0.35 per call |
| ScaleFor busy phones and longer opening hours. | $349 | 2,000 | $0.25 per call |
The short version
- Booking is included on every tier. Rosie keeps booking and live transfer behind its $149 plan.
- The overage rate is on the pricing page. Rosie, Ruby, Slang and AnswerConnect do not publish theirs.
- Calls are counted, not minutes, so a long useful conversation costs the same as a short one.
Questions people ask about this list
What happens when the AI cannot answer?
It depends on the vendor, and that is the most important question on this page. Smith.ai routes to its own human team. GreetKeeper transfers to your team, then tries a second number you nominate. Ask each vendor to describe the mechanism.
How do I check what the assistant handled?
Read the transcripts. Every call arrives as a transcript and a short summary, with the outcome: booked, answered, transferred or message taken. A week of those tells you more about your own calls than any category statistic.
Is an AI answering service the same as an AI receptionist?
The terms are used interchangeably by most vendors, including us. Historically answering service implied message-taking and receptionist implied booking and routing, and that distinction has largely dissolved.
Why is GreetKeeper first on a list it wrote?
Because the handoff is the subject of this page, and ours is a rule you write rather than a behavior you accept. Transfer sits on the $49 plan, with a second fallback number and a text to the on-call person.
