AI Receptionist vs Answering Service: Which Should Answer Your Phone?
A live answering service puts a trained person on your calls and bills per call or per minute. An AI receptionist answers for a flat monthly fee, takes several calls at once, and some book the appointment on the call. A person handles the unusual call better; the gap in cost grows in the AI's favour as calls rise.
Both pick up when your desk cannot. They differ in who picks up and what happens next: a message for the desk, or an appointment in the book. This page compares them on what the companies publish — Smith.ai and Ruby for live receptionists, Rosie and Goodcall for other AI receptionists, and our own. We sell the AI kind, so read our view with that in mind. Every competitor figure here was read on that company's own pricing page on 9 November 2026; prices change, so check theirs before you decide.
How does an AI receptionist compare with a live answering service?
| Live answering service | AI receptionist (OC Systems) | |
|---|---|---|
| Who answers | A trained person working from a script you agree with the service; Smith.ai and Ruby both answer 24/7 | An AI assistant that says it is one at the start of every call, and hands the caller to a person on request |
| How you pay | Monthly bundles of calls (Smith.ai) or receptionist minutes (Ruby); a busier month costs more | $449 a month plus $900 setup, 1,000 minutes and 1,500 texts included; beyond that at our cost, no markup |
| Booking the appointment | Offered: Smith.ai books into Calendly, Acuity and other schedulers for $1.50 a call extra; Ruby lists scheduling among its plan features | Books, moves and cancels against your real availability on the call, in the monthly fee |
| Reminder before the visit | Not listed on Smith.ai's or Ruby's pricing page; ask them | A call or a text the day before; the patient confirms, or moves the visit on that call |
| The unusual call | A person's judgement: an upset caller, a tangled question, something no script foresaw | Answers from the facts you approved; anything outside them becomes a message or a transfer, never a guess |
| Spanish | Smith.ai sells a dedicated Spanish line at $1.00 a call; Ruby lists 24/7 Spanish and bilingual answering | English and Spanish on the same line, standard, in whichever language the caller starts in |
| Setup fee | None, on both Smith.ai's and Ruby's pricing pages | $900 once: connecting your scheduler, loading the answers you approve, testing with your desk before anything forwards |
When is a live service, or a cheaper AI app, the better choice?
- Your calls need judgement more than scheduling: upset clients, complicated questions, calls no script can foresee
- You get few calls. Smith.ai's live entry plan was 30 calls for $300 a month on 9 November 2026, with no setup fee; at that volume a person costs less than our $449 plus $900 setup
- You want a person to triage after-hours clinical calls; many medical and dental offices keep a live service for those and let an AI take the scheduling
- You only need the phone answered and a message taken, and are happy to set it up yourself: self-serve AI apps such as Rosie (from $49 a month) and Goodcall (from $79 a month) cost less than either of our plans
When is our AI receptionist the better choice?
- Most of your calls are about appointments, and you want them booked, moved and cancelled on the call rather than left as messages for the desk
- You want the confirmation text after the call and a reminder call or text the day before, from the same assistant, with replies that move the visit
- Your phone rings in bursts, and a flat fee with several callers answered at once suits you better than a bill that rises with every call
- Your callers speak Spanish, and you want it on the same line without an add-on
- You are in Orange County and want the setup done in person with your front desk, then watched together for the first weeks
What do Smith.ai, Ruby, Rosie and Goodcall charge, and what do they include?
Five services that answer a small business's phone, side by side, as each one describes itself on its own pricing page. Two are live receptionists, three are AI. They bill in four different ways — per call, per minute of a person's time, per minute of the AI's time, per caller — so the cheapest one depends on your calls, not on the headline price.
| Item | Smith.ai (live) | Ruby (live) | Rosie (AI) | Goodcall (AI) | OC Systems (AI) |
|---|---|---|---|---|---|
| Who answers | Live receptionists, 24/7; Smith.ai also sells a separate AI receptionist | Live receptionists, 24/7 | An AI agent | An AI phone agent | An AI assistant, with a person on request |

What does each cost at your call volume?
Smith.ai's live plans are sold by the call and ours by the month, so they line up cleanly at the volumes Smith.ai's plans include. The table leaves out add-ons, such as Smith.ai's $1.50 a call for booking, and our one-time $900 setup fee, which Smith.ai does not charge.
At thirty calls a month a person costs less. Somewhere between thirty and ninety calls the two cross, and from then on a per-call bill keeps rising while a flat fee does not, as long as the calls fit in the included minutes.
| Calls a month | Smith.ai live receptionists (its plan for that many calls) | OC Systems AI receptionist |
|---|---|---|
| 30 | $300 a month (Starter) | $449 a month; the included 1,000 minutes cover calls averaging up to 33.3 minutes |
| 90 | $810 a month (Basic) | $449 a month; the included 1,000 minutes cover calls averaging up to 11.1 minutes |
| 300 | $2,100 a month (Pro) | $449 a month; the included 1,000 minutes cover calls averaging up to 3.3 minutes |
Smith.ai figures read on smith.ai/pricing on 9 November 2026. A call's length does not change Smith.ai's price; it decides whether our included minutes cover the month, and minutes beyond them are billed at our cost. Ruby bills by the minute, Rosie by AI minutes and Goodcall by unique caller, so they do not fit one row; their plans are in the table above.
Is an AI receptionist the same as an AI answering service?
The names are used loosely, and the difference that matters is what happens after hello. Some products sold as an AI answering service answer from your facts and take a message. Others book: into a calendar link, or into the schedule your desk already runs. Rosie's entry plan texts the caller a booking link, and its higher plans book onto Google Calendar or Calendly. Smith.ai sells live receptionists and an AI receptionist side by side, so with them the choice can be between two plans at one company.
Before comparing prices, ask the same question of each: on a Friday evening, does the caller hang up with an appointment, a link, or the promise of a call back?
What should a dental office ask an answering service before signing?
A dental answering service has two jobs: catch the calls the desk cannot take, and send anything clinical to the right place. These questions make two quotes comparable, live or AI.
- Does it book into our practice-management system or scheduler on the call, or take a message for the desk to book later?
- Is booking in the price, or charged per call or per booking on top?
- Does it call or text patients the day before, and can a patient reschedule by replying?
- What happens to an after-hours caller describing pain, swelling or an emergency?
- Is Spanish on the same line, an add-on, or a separate number?
- How is a busy month billed: per call, per minute, per caller, or flat with included minutes? What did our busiest month last year cost under each?
- Is there a setup fee, a minimum term, or a notice period?
- Who can hear the recordings and read the transcripts, and what will the service sign with a healthcare practice before it starts?
What does the OC Systems AI receptionist cost?
AI Phone Receptionist: $449 a month plus a one-time $900 setup, 1,000 minutes and 1,500 texts included; beyond that, minutes and texts are billed at what they cost us, with no markup. It books, moves and cancels appointments, sends the confirmation text, makes the reminder call the day before and reads the replies.
AI Receptionist Starter: $299 a month plus $300 setup, 400 minutes included. It answers, takes a message with the caller's name, number and reason, and hands the call to a person on request. It does not book, remind or text back; that is what the full plan adds.
Both are month to month, with no per-call charge. We are in Costa Mesa, and the setup is done with your front desk in the room, on a test number first; nothing forwards until you say so.
So which should answer your phone?
If your calls need a person's judgement, or you get few enough calls that a per-call bundle costs less than a flat fee, a live service such as Smith.ai or Ruby is the sound choice, and many offices keep one for after-hours clinical calls anyway. If you only need the phone answered and can set it up yourself, a self-serve app such as Rosie or Goodcall costs less than we do. If most of your calls are about appointments, and you want them booked, confirmed and reminded without the desk calling anyone back, that is the job our AI receptionist is built and priced for. Judge it on a call, not on this page.
