AI receptionist vs answering service: which one should answer your calls?

An AI receptionist is software that answers every caller at once and books appointments for a monthly plan. A human answering service puts trained people on the line and bills by the minute or the call. An IVR menu only routes callers, and voicemail only records them. Where most calls are bookings and routine questions, an AI receptionist that hands over to a person is usually the better fit.

An AI receptionist, a human answering service, an IVR phone menu and voicemail are four ways to deal with a call the business cannot pick up. They differ in one thing above all: whether the caller gets an answer and a result during the call, or only a route or a recording and a wait for a callback.

• AI receptionist: software that speaks with the caller in natural language, answers from the knowledge base of the business, books appointments and passes the call to a person when needed. Also called an AI phone agent or a virtual receptionist.
• Human answering service: an outside team of receptionists who answer in the name of the business, follow its script, take messages, book and transfer calls.
• IVR phone menu: a recorded menu in the phone system (“press 1 for bookings”) that sends the caller to a department or plays information.
• Voicemail: a greeting and a recording that someone listens to later.

An AI receptionist and a human answering service both hold a conversation and finish the job on the call; an IVR menu and voicemail do not. The table compares the four on what the caller gets, what can be done during the call, availability, languages, messages and cost. Prices are taken from providers’ own pricing pages read on 2 October 2026.

An AI receptionist handles a call in five steps: it picks up, understands the request, answers, books, and hands over when the call is not for it. A human receptionist follows the same steps from a script. An IVR menu stops at the routing step, and voicemail stops at the recording.

1. The call arrives directly or by call forwarding from the business number, for example after hours or after a set number of rings.
2. The AI receptionist greets the caller and listens to free speech, not key presses.
3. It answers routine questions from the knowledge base: prices, opening hours, address, how to prepare for a visit.
4. For a booking it finds a free time in the connected booking system and writes the appointment there. See which systems Solwees works with.
5. It hands over when a person is needed. In Solwees a caller reaches a person only in working hours and only if a team member accepts the call in the mobile app within 30 seconds; otherwise Solwees tells the caller that a manager will call back. The call is saved with a transcript and a recording.

A human answering service costs more per call because the business pays for people’s time: published plans in October 2026 start at $99 to $300 a month for 50 minutes or 30 calls.^[1-3] An AI receptionist is priced as software: Goodcall $79, Marlie $99 with booking, Smith.ai Pro $150, Solwees €249 a month.^[4-6] An IVR menu and voicemail come with the phone system.

• Ruby (people): 50 receptionist minutes for $250 a month, 100 minutes for $395.^[2]
• Smith.ai (people): 30 calls for $300 a month, then $11.50 a call.^[3]
• PATLive (people): $49 a month plus $2.99 a minute, or 50 minutes for $99 a month.^[1]
• Smith.ai AI Receptionist: 25 calls a month free, then $3.00 a call; Pro $150 a month.^[6]
• Marlie (AI): $99 a month with 500 minutes and booking; its $49 plan only takes messages.^[5]
• Goodcall (AI): $79 a month per agent with unlimited minutes and 100 unique callers.^[4]
• Solwees (AI): as of October 2026, Studio €249 a month per location with 100 call minutes; Solo €99 a month answers chats, and 100 call minutes cost €39 once. See pricing.
• Zadarma (IVR): a cloud phone system from €0 a month with 4 voice menus.^[7]

Smith.ai sells both and shows the gap inside one company: its live receptionists cost $300 a month for 30 calls, which is $10 a call, while its AI Receptionist costs $2 to $3 a call.^{[3, 6]} Check what is billed: a minute, a call, a unique caller, or a plan with a limit.

A human answering service is the better choice when the call itself is the service: a caller who is upset, a case that does not fit any rule, or a first conversation that decides whether a client signs. People hear what is not said, bend the script and take responsibility. An AI receptionist should pass such calls on.

• Emotional calls: complaints, bad news, a frightened patient or pet owner.
• Complex or unusual cases: anything that needs judgement, an exception or a negotiation.
• Legal intake: a law firm qualifies a potential client on the first call. Smith.ai says roughly 80% of its customers are law firms.^[8]
• Low volume, high value: a few calls a week where each one is worth a long conversation.

An AI receptionist is the better choice when calls are frequent, similar and end in a booking: a salon, a clinic, a restaurant, a repair company. It answers at once at any hour and writes the appointment into the booking system. It can also answer messages, which a phone-only service does not.

• Booking and rescheduling: the appointment goes straight into the booking system.
• Routine questions: prices, hours, address, availability.
• Many languages: Solwees holds conversations in 50+ languages.
• Messages as well as calls: the same Solwees assistant answers WhatsApp, Instagram, Telegram, Messenger, website chat and email.
• Peaks and nights: no queue at a busy hour, no voicemail at night.

An AI receptionist knows only what the business gave it and does only what it is allowed to do. It does not decide on refunds or exceptions, does not calm an angry client the way a person can, and should not guess. A well set up AI receptionist says it will check and brings in a person.

Solwees has limits of its own, as of October 2026. Plans are priced per location. Phone answering starts at the Studio plan or needs a pack of minutes, and minutes above the plan cost €0.40 each under a mandatory spending cap; at the cap calls stop.

A common setup combines an AI receptionist with people: the AI receptionist takes every call first, finishes the routine ones and passes the rest to a person with a short summary. The people can be the business’s own staff, or a human answering service for nights. Four rules make the handoff work.

1. List the reasons for a handoff: a request for a person, a complaint, a refund, anything missing from the knowledge base.
2. Decide who gets the call and where: a mobile app, a desk phone, an on-call number.
3. Make a missed handoff visible. In Solwees a missed call for the manager raises an alert in the app and, if connected, in Telegram. See how handover works.
4. Read the transcripts every week and add the missing answers to the knowledge base.

Choose between an AI receptionist and an answering service by the kind of calls the business gets. Count the calls in a week, mark how many are bookings and routine questions and how many need a person, and check where clients write as well as call. The answer is usually clear from these three numbers.

• Mostly bookings and routine questions, by phone and in messengers: an AI receptionist. Start with the Solwees phone agent.
• Mostly sensitive or complex conversations: a human answering service.
• Both kinds: an AI receptionist first, with a handoff to your staff or to a service.
• Several departments and staff who pick up: an IVR menu is enough to route.
• A few calls a week, nothing urgent: voicemail and a quick callback.
