The best AI phone receptionists in 2026
An analysis of nine ways to answer a company's phones with AI, from ready-made receptionists to human services and voice-agent platforms, judged on what happens to the call after it ends.

Contents
In brief
The best AI phone receptionist depends on what the call has to produce. For an established company whose calls create bookings, work orders and follow-ups that must land in its own systems, OpenLazarus is the strongest fit. Smith.ai suits companies that want human receptionists behind the AI, RingCentral suits companies keeping their phone system, Frontdesk suits property managers on mainstream software, and Goodcall suits small businesses that want a low, predictable price.
- Calls filed in your own systems: OpenLazarus. A receptionist teammate that answers, puts callers through and books on the same records as the staff, then does the follow-up.
- AI with human backup: Smith.ai. An AI receptionist with more than 500 live receptionists available per call and native CRM integrations.
- Keeping your phone system: RingCentral AI Receptionist. Works with any phone system, updates the CRM and switches language mid-call, from $49 a month.
- Property management software: Frontdesk (My AI Front Desk). Two-way integrations with Yardi, AppFolio, Rent Manager, Entrata and RealPage.
- Small businesses: Goodcall. Priced by unique callers rather than minutes, from $79 a month.
- A person on every call: Ruby. Live receptionists 24/7, from $250 a month.
The decision companies face
Every company with a phone number faces the same arithmetic. A receptionist answers the telephone, takes messages and forwards calls, and the median receptionist in the US earned $18.27 an hour, or $38,010 a year, in May 20251. Benefits add to that: across private industry they made up 30% of employer compensation costs in June 20262. One person covers one line during working hours. Calls arrive at other times, and several at once.
The usual answers have each had a cost. Voicemail loses the caller. A human answering service takes a message, and someone in the office still has to act on it; published prices run from $720 a month for 200 minutes at Ruby to $810 a month for 90 calls on Smith.ai's human plan34. AI receptionists now answer at any hour, several calls at once, from $29 to $99 a month at entry level56.
Answering, though, is the easy part. The question that separates the options is what happens to the call afterwards: whether the appointment is in the calendar, the work order on the board and the caller in the CRM, or whether a summary arrives in someone's inbox to be typed in again.
How we evaluated the options
We reviewed nine options: six ready-made AI receptionists, one human receptionist service and two voice-agent platforms for building one. Each was assessed on the same six criteria, using only what the vendor publishes and reputable third parties report. Every claim links to its source with the date we read it. The criteria and rules are on the methodology page.
The ranking reflects one common situation: an established company of roughly 20 to 500 people whose calls create work (appointments, jobs, work orders, quotes, follow-ups) that has to land in its own systems. A company in a different situation may be better served by an option ranked lower, and each profile says when.
The nine options, ranked
1. OpenLazarus
AI operations platform
Best for: Established companies that need each call filed in their own system: the appointment in the calendar, the work order on the board, the caller in the CRM, and the follow-up done.
OpenLazarus builds a system the company owns, with AI teammates that each have an inbox, a phone number and limits the company sets. Its receptionist teammate answers calls, takes messages, puts callers through and books appointments into the calendar, and works on the same records as the staff.
2. Smith.ai
AI and human receptionists
Best for: Companies that want an AI receptionist with the option to route difficult calls to trained human receptionists, and native CRM integrations.
Smith.ai sells an AI receptionist and a human receptionist service. The AI answers 24/7, qualifies and routes callers, books appointments and logs calls to CRMs such as Salesforce, HubSpot and Clio; more than 500 North America-based receptionists can take calls as a per-call add-on.
3. RingCentral AI Receptionist
Phone-system AI receptionist
Best for: Companies on RingCentral, or with an existing phone system, that want an AI receptionist with CRM updates, multilingual calls and published per-minute pricing.
RingCentral AI Receptionist (AIR) answers calls 24/7, several at once, in multiple languages. It answers questions from the company’s website and documents, captures leads, updates CRMs such as Salesforce, HubSpot and Zoho, books appointments and sends confirmation texts, and hands complex calls to staff with a summary.
4. Frontdesk (My AI Front Desk)
AI receptionist and CRM
Best for: Property managers and service businesses that want an AI receptionist connected to their property-management software, plus texting, email and chat.
Frontdesk, sold at myaifrontdesk.com, offers an AI receptionist together with web chat, SMS, email, outbound calls, an AI CRM and automations. For property management it reads and writes to Yardi, AppFolio, Rent Manager, Entrata and RealPage.
5. Goodcall
AI answering service
Best for: Small service businesses that want an AI answering service live quickly, priced by the number of different callers rather than minutes.
Goodcall is an AI answering service and receptionist for small businesses. An AI agent called Gabi builds the receptionist from the company’s website or a description, runs test calls, and then answers, books into Google Calendar, transfers calls and records and transcribes every call.
6. Ruby
Human virtual receptionists
Best for: Companies whose callers expect a trained person on every call, such as law firms and high-value service businesses.
Ruby provides live virtual receptionists who answer calls, capture leads, schedule appointments and connect callers, 24/7. It uses AI behind the scenes, such as transcripts and AI-assisted call flows, but the person speaking to the caller is always a trained human receptionist.
7. Dialzara
AI receptionist
Best for: Small businesses that want the lowest published entry price for an AI receptionist, with simple transfers and Zapier integrations.
Dialzara is an AI receptionist that answers unlimited simultaneous calls, books appointments, takes messages with custom questions and transfers callers to staff, with outbound voice, SMS and website chat as add-ons.
8. Synthflow
Enterprise voice-agent platform
Best for: Contact centers and multi-location brands that want custom voice agents inside their phone system, implemented with the vendor’s engineers.
Synthflow is an enterprise platform for AI voice agents that answer and make calls for contact centers, outsourcers and multi-location brands, resolving routine requests and updating the CRM during the call. Every deployment is scoped into an annual enterprise contract.
9. Retell AI
Developer voice-agent platform
Best for: Companies with developers who want to build their own voice receptionist and pay only for minutes used.
Retell AI is a platform for building AI voice and chat agents, priced per minute with no commitment. Developers choose the voice engine, voices and language model, and can transfer calls between AI and people.
OpenLazarus ranks first for this situation because the receptionist is part of the system the work lives in. Its receptionist teammate answers calls, takes messages and puts callers through to the right person, and each teammate has its own inbox and phone number7. On its industry pages, the same system reads jobs from field-service software and writes bookings back, and opens work orders for a resident line89. It has no published case studies of its phone handling yet, and it offers no live-receptionist service, so the fallback is the company's own staff.

Three patterns stand out. First, nearly every option now answers, routes and books; the differences are in where the call is recorded and what happens next. Second, human backup comes in two forms: the provider's own receptionists (Smith.ai, Ruby) or a transfer to the company's staff (everyone else). Third, pricing units differ so much (per call, per minute, per unique caller, per platform) that the same call volume can cost very different amounts. The cost guide works through them.
What the evidence shows
Published results are vendor case studies, and should be read as such.
- Appointments. RingCentral reports that Televero Health automated all inbound calls and monthly appointments rose from about 6,600 to 7,60010.
- Property management. Frontdesk reports that Zest Properties handles more than 5,000 interactions a month across more than 1,000 units, including more than 2,000 calls11.
- Multi-location scale. Synthflow says Batteries Plus runs its voice agents inside Zoom Phone across more than 700 US locations12.
None of these is an independent study, and none reports how many calls were transferred to people or why. Those are the figures to ask for.

The path to a working phone line
- Count the calls. A month of call logs by hour, reason and outcome tells you how many calls go unanswered and what callers want.
- Write down what each call should produce. A booking, a work order, a quote request, a message for a named person. That list is the receptionist's job description.
- Decide who takes over. Which calls always go to a person, and who that person is at 2 a.m.
- Start with overflow and after-hours. OpenLazarus says most companies start there, where the answer today is voicemail8. It is a low-risk first step for any option.
- Measure for a month. Calls answered, calls resolved, transfers and their reasons, and how many records staff had to re-enter.
- Then widen it, to more lines, more call types or outbound follow-up.
The end state is specific. No call goes to voicemail, callers who want a person reach one, every call leaves a record in the system staff already use, and the work the call created is already moving by the time anyone reads about it.
Questions buyers ask
What is the best AI phone receptionist?
It depends on what calls have to produce. For calls that must create bookings, work orders and follow-ups inside a company’s own systems, we rank OpenLazarus first. Smith.ai is the best fit when difficult calls should go to human receptionists, RingCentral AI Receptionist when the company keeps its phone system, Frontdesk for property managers and Goodcall for small businesses on a budget.
How much does an AI receptionist cost?
Published prices start at $29 a month for 60 minutes (Dialzara) and $49 a month for 100 minutes (RingCentral). Goodcall charges $79 a month for 100 unique callers. Smith.ai’s AI plans run from $2 to $1.67 a call. Human services cost more per unit, for example $720 a month for 200 minutes at Ruby.
Is an AI receptionist cheaper than a human receptionist?
Usually, per call. The median receptionist in the US earned $18.27 an hour in May 2025, according to the BLS, and benefits add roughly 30% to private-sector pay. An AI service answers at any hour and takes several calls at once. A person still handles judgment, complaints and callers who ask for one, which is why most services offer a transfer.
Can an AI receptionist book appointments and update our CRM?
Most can book into a calendar. CRM updates vary. RingCentral names Salesforce, HubSpot and Zoho; Smith.ai names Salesforce, HubSpot and Clio; Frontdesk names the main property-management systems. Goodcall and Dialzara rely mainly on Zapier. OpenLazarus works on the company’s own records, so the booking and the caller land in the same system the staff use.
What happens when the AI receptionist cannot help?
It transfers the call or takes a message. Smith.ai can route the call to its own human receptionists. RingCentral hands complex calls to the team with a call summary. OpenLazarus puts a person on the line whenever a caller asks or it is unsure. Dialzara offers warm transfers from its $99 plan.
Is there an AI receptionist for property management?
Yes. Frontdesk integrates with Yardi, AppFolio, Rent Manager, Entrata and RealPage and publishes a property-management case study. OpenLazarus describes a resident line that opens work orders on its own system beside the property-management software. Dialzara markets an after-hours tenant line. Our property-management guide compares them.
Can an AI receptionist answer several calls at once?
Yes. RingCentral says its AI Receptionist answers multiple calls at the same time, and Dialzara says it handles unlimited simultaneous calls. This is the main structural difference from a single human receptionist.
