"The best AI voice agent for answering business phone calls depends on who sets it up. For a small business that wants calls answered this week, Goodcall and RingCentral AI Receptionist are ready-made. For a team with a developer, Retell AI, Vapi and Bland AI are the platforms to build on. For a large contact center, PolyAI, NiCE Cognigy and Parloa sell enterprise platforms. Every price here was read on the vendor's own page on 11 October 2026 and checked again on 21 October 2026."
Key Takeaways
- 1There is no single best AI voice agent for business phone calls. Three kinds of product share the name: ready-made products you set up yourself (Goodcall, RingCentral AI Receptionist), platforms a developer builds on (Retell AI, Vapi, Bland AI) and live receptionist services (Ruby, Smith.ai).
- 2Published prices on 11 October 2026: Goodcall $79, $129 or $299 a month with no per-minute charge. RingCentral AI Receptionist from $49 a month with 100 minutes included. Smith.ai AI Receptionist free for 25 calls a month, then $150 or $500 a month.
- 3Developer platforms price by the minute. Retell AI lists $0.07 to $0.31. Vapi lists $0.05 for its own platform, with voice and language providers charged on top. Bland AI lists $0.14 on its Start plan.
- 4We put the question to ChatGPT, Claude, Gemini, Perplexity and Google's AI answers on 9 October 2026. Across 14 answers, Retell AI was named in all 14, Smith.ai in 11, and Goodcall and Bland AI in 9 each.
- 5Synthflow states "Enterprise contracts start at $30,000 annually" and lists one plan on its pricing page, so it suits a large contact center more than a small office.
- 6The companies that develop voice AI agents fall into four groups: developer platforms, enterprise contact center platforms, ready-made small business products, and firms that build a custom agent for you (Intellectyx, Master of Code Global, Appinventiv, RaftLabs and FactoryJet).
- 7Picked by company size: an office under 10 staff starts with Goodcall, RingCentral or Smith.ai; a team with a developer builds on Retell AI, Vapi or Bland AI; a contact center looks at Synthflow, PolyAI, NiCE Cognigy or Parloa, or a custom build. Groovy Web puts a single-purpose custom build at $3,000 to $12,000.
- 8For a medical practice the deciding line is the Business Associate Agreement. Vapi lists a HIPAA add-on with a BAA at $2,000 a month, Bland AI says it signs a BAA, and RingCentral says its AI Receptionist is designed to support HIPAA compliance.
- 9At least three of the eight price pages changed between our reading on 7 September 2026 and 11 October 2026. None changed between 11 and 21 October. Read the vendor page on the day you buy.
The short answer. The best AI voice agent for answering business phone calls depends on who will set it up. For a small business that wants calls answered this week, Goodcall ($79 to $299 a month) and RingCentral AI Receptionist (from $49 a month) are ready-made products. For a team with a developer, Retell AI, Vapi and Bland AI are platforms priced by the minute. For calls that need a person behind the AI, Smith.ai adds live receptionists. For a large contact center, PolyAI, NiCE Cognigy and Parloa sell enterprise platforms. If none of those fits and you have one call to be handled in your own system, a custom build is the fourth route: Groovy Web puts a single-purpose small business build at $3,000 to $12,000 in 2026, and Master of Code Global puts a mid-tier agent with CRM integration at $25,000 to $50,000. The companies that develop voice AI agents, including the firms that build custom ones, are listed by group further down.
Who wrote this. FactoryJet wrote this list and is on it. We build custom AI voice agents as a service, so we appear among the firms that build them and in none of the product entries. No company paid to appear. Every price and description below was read on the company's own site on 11 October 2026 and is linked under Sources.
We also checked which products the AI assistants name. On 9 October 2026 we put this exact question to ChatGPT, Claude, Gemini, Perplexity and Google's AI answers and read all 14 replies. Retell AI was named in all 14, Smith.ai in 11, Goodcall and Bland AI in 9 each, Synthflow in 8 and Vapi in 7. All six are covered below with their published prices.
Best AI voice agents for business phone calls, by kind of buyer
Each price is the vendor's own published list price, read on 11 October 2026. The units differ because the vendors bill in different units: by the month, by the minute or by the call.
| If you are | Product | Published price | What you are buying |
|---|---|---|---|
| A small business that wants calls answered this week | Goodcall | $79, $129 or $299 a month. No per-minute charge | Ready-made product |
| A business that wants an add-on to its phone system | RingCentral AI Receptionist | From $49 a month standalone or $39 a month with RingEX. 100 minutes included, then $0.50 a minute | Ready-made product |
| A business that wants live receptionists behind the AI | Smith.ai AI Receptionist | Free for 25 calls a month, then $150 or $500 a month | AI first, people on call |
| A business that wants a person on every call | Ruby | $250 a month for 50 minutes, up to $1,725 a month for 500 minutes | Live receptionists |
| A team with a developer | Retell AI | $0.07 to $0.31 a minute, pay as you go | Developer platform |
| A team with a developer | Vapi | $0.05 a minute for the platform, with voice and language providers charged on top | Developer platform |
| A team with a developer | Bland AI | $0.14 a minute on Start. $0.12 a minute plus a $299 a month platform fee on Build | Developer platform |
| A large contact center | Synthflow | "Enterprise contracts start at $30,000 annually" | Enterprise platform |
PolyAI, NiCE Cognigy and Parloa also sell enterprise platforms. Their entries are in the companies section further down.
Which AI voice agent fits your company size in 2026
The right pick depends mostly on company size and on who will set it up. The products are the same ones covered below. Prices are each vendor's list price, checked on 21 October 2026. The full cost breakdown, with build ranges for each size, is in our AI voice agent cost guide for 2026.
| Company size | Main call job | Start with | Check first |
|---|---|---|---|
| 1 to 10 staff: a trade, clinic front desk or law office | Answer every call, take the details, book the job | Goodcall ($79 to $299 a month), RingCentral AI Receptionist (from $49), Smith.ai AI Receptionist (free for 25 calls) | Whether it writes into the booking software you already use |
| 10 to 50 staff with someone technical | Bookings, transfers, a CRM update after each call | Retell AI ($0.07 to $0.31 a minute), Vapi ($0.05 plus providers), Bland AI ($0.14) | Who designs and tests the call flow, and the concurrent call limit |
| 50 to 500 staff, several call types | Calls that read and write your CRM, orders or payments | A developer platform with a build partner, or a custom build ($25,000 to $50,000 mid-tier, per Master of Code Global) | Which systems the agent must write into, named in writing |
| Contact center | High volume, several languages, a live queue behind it | PolyAI, NiCE Cognigy, Parloa, Sierra, or Synthflow (from $30,000 a year) | Concurrency, hand-off to the queue, and a reference in your industry |
| Healthcare, insurance or finance, any size | Calls that carry patient or policy data | A vendor that signs a BAA or DPA (see the compliance table below) | The signed agreement and how long recordings are kept |
Three kinds of product share one name
| Ready-made products | (Goodcall, RingCentral AI Receptionist, Smith.ai AI Receptionist) sell a working receptionist that you set up yourself for a flat monthly price. |
|---|---|
| Developer platforms | (Retell AI, Vapi, Bland AI) sell minutes on a platform. The rate buys the building blocks. Someone on your side designs the conversation, connects your calendar and CRM, and tests what happens when a caller says something unexpected. |
| Live receptionist services | (Ruby, and the human-first plans at Smith.ai) sell people answering your phone. |
A per-minute platform rate set against a live answering service is a bag of flour set against a delivered cake. Decide which of the three you are buying before you compare prices.
Four things to check on a pricing page before you sign up
| Whether the entry price is an enterprise contract. | Synthflow's pricing page states "Enterprise contracts start at $30,000 annually" and listed one plan, Enterprise, on 11 October 2026. Synthflow describes itself as a voice platform for enterprises, so a small office should start with the ready-made products. |
|---|---|
| What a health data add-on costs. | Vapi lists $0.05 a minute for its platform. It also lists a health data add-on, which includes a Business Associate Agreement, at $2,000 a month. A medical or dental practice should read the add-on list before the per-minute rate. |
| What a platform fee does to the lower rate. | Bland AI's Build plan lowers the rate from $0.14 to $0.12 a minute and adds a $299 a month platform fee. Match the plan to your call volume before you pick the lower rate. |
| Whether the page has changed since the article you read. | We first read these eight price pages on 7 September 2026. By 11 October 2026 at least three had changed. Goodcall's top plan moved from $249 to $299 a month. Bland AI's Scale plan at $0.11 a minute was no longer listed, and the third plan shown was a custom Enterprise plan. Vapi's entry plan listed 10 concurrent lines in September and lists 4 now. We read all eight again on 21 October 2026 and none had changed since 11 October. Read the vendor page on the day you buy. |
Compliance checks by vendor: HIPAA, SOC 2, GDPR and outbound calls
For a medical, legal or financial office, the vendor's compliance terms matter as much as its price. Here is what each vendor's own page said on 21 October 2026. Where a page we read stated no terms, the table says so; the vendor may still offer them. Ask for every answer in writing.
| Vendor | What its own page says |
|---|---|
| Bland AI | SOC 2 Type I and Type II, HIPAA compliant with a signed BAA, GDPR compliant with a DPA, PCI DSS self-attested |
| Retell AI | "SOC 2 certified, HIPAA-ready", with HIPAA / BAA, custom DPA and custom BAA in its plan comparison |
| Vapi | HIPAA add-on with a Data Processing Agreement and Business Associate Agreement at $2,000 a month |
| RingCentral AI Receptionist | "designed to support HIPAA compliance", with encryption, access controls and audit logging |
| Ruby | Lists HIPAA-compliant services among its plan features |
| Goodcall, Smith.ai, Synthflow | The pricing pages we read did not state HIPAA or BAA terms. Ask the vendor. |
Two rules apply whichever product you choose. Recording consent varies by US state, and some states require every party on the call to agree, so have the agent say the call is recorded. For outbound calls, the FCC ruled on 8 February 2024 that AI-generated voices are "artificial" under the Telephone Consumer Protection Act, and its rules require prior express written consent before telemarketing robocalls. See the FCC news release.
The eight products, one by one
Goodcall, for a small business that wants a flat monthly price
Goodcall lists $79, $129 and $299 a month and states "No per-minute charges". It bills per unique customer, which it defines as one phone number once a month. The three plans cover 100, 500 and 2,000 unique customers a month, and extra customers are billed at 79 cents, 26 cents and 15 cents each.
A long call and a short call cost the same, so a busy month does not change the bill unless the number of different callers goes up. Every plan includes a local number, and you can build a free demo agent before you connect one. See Goodcall pricing.
RingCentral AI Receptionist, for a business that wants an add-on to its phone system
RingCentral's pricing page states the product is "available as a standalone plan starting at $49 per month, which includes 100 minutes of usage, or as an add-on to RingEX, starting at $39 per month, also with 100 minutes included". Minutes beyond that are $0.50 each, and both versions come with a 14-day free trial.
It can be trained on your website, FAQs and uploaded documents, captures leads with intake questions you write, and logs caller details to Salesforce, HubSpot and Zoho. RingCentral states it can be layered on existing phone systems "using call forwarding or SIP-based integrations", and that it supports English, Spanish, French, Italian, German and Portuguese. See RingCentral AI Receptionist pricing.
Smith.ai, for calls that need a person on standby
Smith.ai sells two things. Its AI Receptionist lists a Free plan with 25 calls a month ($3.00 a call after that), Pro at $150 a month and Enterprise at $500 a month. The AI answers first, and a call can be transferred to a live receptionist when something complex comes up. See Smith.ai AI Receptionist pricing.
Its human-first receptionist plans list $300 a month for 30 calls, $810 for 90 and $2,100 for 300, with extra calls at $11.50, $10.50 and $8.50 each. Those plans are "Live-staffed with expert agents 24/7" and carry a 30-day money-back guarantee, no setup fees and "No charge for spam". Both products are priced per call, where most of the others on this page are priced by the minute or the month. See Smith.ai receptionist pricing.
Ruby, for a person on every call
Ruby describes its service as "100% live, personalized communication". Its plans are $250 a month for 50 minutes, $395 for 100, $720 for 200 and $1,725 for 500 minutes. Website chat is priced separately from $143 a month for 10 chats, with 20% off chat when it is added to a receptionist plan. Ruby states there are no additional fees for activation, onboarding, setup or customization.
Ruby is on this page because it is the choice an AI voice agent is measured against. If every caller should reach a person, this is the kind of service to price first. See Ruby plans and pricing.
Retell AI, a developer platform with pay-as-you-go pricing
Retell AI lists "$0.07-$0.31 / min for AI Voice Agents", with $10 in free credits and 20 free concurrent calls. Extra concurrent calls are $8 each a month and Retell phone numbers are $2 a month. The rate depends on the voice and language options you pick, and the pricing page has an estimator that shows the rate for each choice. An Enterprise plan with custom pricing adds custom contract terms and single sign-on.
Retell AI was the one product named in all 14 of the AI answers we read on 9 October 2026. See Retell AI pricing.
Vapi, a developer platform that lets you choose each provider
Vapi is "$0 to start", then $0.05 a minute for its own platform, with the transcription, language and voice providers you choose charged on top. The usage-only plan includes $5 in free credits, 4 concurrent calls and 14 days of raw data retention. A Core package at $29 a month raises that to 10 concurrent calls and 30 days.
Vapi does not include a phone line in that rate: it lists Twilio inbound at $0.008 a minute and outbound at $0.014 a minute as pass-through, beside Vonage and Telnyx. Twilio's own US list prices a local number at $1.15 a month (Twilio voice pricing). Extra concurrent lines are $10 each a month. A health data add-on that includes a Business Associate Agreement is $2,000 a month. See Vapi pricing.
Bland AI, a developer platform with one per-minute rate
Bland AI's Start plan is "$0.14 /min" with "$0 platform fee. No card required." It includes 10 concurrent calls and 100 calls a day. The Build plan is "$0.12 /min" with a "$299/month platform fee", 50 concurrent calls and 2,000 calls a day. Enterprise is priced to your volume.
Bland AI states that the per-minute rate includes the language model, transcription and voices. Transferred call time is listed separately at $0.05 a minute on Start and $0.04 on Build. See Bland AI pricing.
Synthflow, an enterprise platform
Synthflow's pricing page states "Enterprise contracts start at $30,000 annually", with final pricing "scoped around call volume, concurrency, telephony setup, integrations, security needs, and launch support". It describes itself as "the leading AI Voice Platform for enterprises". It was named in 8 of the 14 AI answers we read, so a small business is likely to meet it early. It suits a large contact center. See Synthflow pricing.
Which companies develop voice AI agents
The companies that develop voice AI agents fall into four groups: platforms a developer builds on, platforms for enterprise contact centers, ready-made products for small businesses, and firms that build a custom agent for you.
On 9 October 2026 we asked ChatGPT, Claude, Gemini, Perplexity and Google's AI answers to name the top companies that develop voice AI agents, and read all 14 replies. Retell AI, Vapi, Bland AI, PolyAI and ElevenLabs were named in all 14. NiCE Cognigy was named in 11, Deepgram in 10, Synthflow in 9, Sierra in 8, LiveKit in 7 and Parloa in 5. The table gives each company's own description, read on its site on 11 October 2026.

Platforms a developer builds on
Retell AI, Vapi and Bland AI are covered with their prices above. Three more were named often in the AI answers we read.
ElevenLabs sells an agent platform called ElevenAgents. Its site says you can "Build, test and deploy AI agents for your website, app or call center", across voice, chat and email, in more than 90 languages. See ElevenAgents.
Deepgram sells a Voice Agent API that combines speech-to-text, the language model step and text-to-speech in one API. Its page states the API is "Priced at $4.50/hr". See Deepgram Voice Agent API.
LiveKit describes itself as "An open source framework and developer platform" for building agents, and its site shows how to connect an agent to phone calls. It suits an engineering team that wants to own the whole build. See LiveKit.
Platforms for enterprise contact centers
PolyAI calls itself enterprise voice AI. Its site says it "builds dialog agents that handle your most critical enterprise conversations". See PolyAI.
NiCE Cognigy sells AI agents for contact centers across voice and chat. Its site says "Easily deploy AI Agents in your contact center" and names Voice AI Agents for phone conversations. See NiCE Cognigy.
Parloa describes itself as "the AI agent management platform for enterprise CX", for building, testing and scaling voice and chat agents. See Parloa.
Sierra builds customer-facing agents that run on several channels. Its site says "Deploy a single agent across chat, SMS, WhatsApp, email, voice, and ChatGPT" and describes outcome-based pricing. See Sierra.
Synthflow is covered with its price above.
Ready-made products for small businesses
Goodcall, RingCentral AI Receptionist and Smith.ai are covered with their prices above. Each one is a product you can sign up for and set up yourself.
Firms that build custom AI voice agents
A build firm designs the agent around your calls and connects it to your systems. You hire it for a project, where the companies above sell a product or a platform. The five firms below describe custom voice agent work on their own sites. They are grouped by the buyer each site addresses and listed in no ranked order. More build firms are reviewed in our AI voice agent development companies compared.
For large companies in banking, insurance, healthcare and contact centers
Intellectyx states that it "builds enterprise AI voice agents for healthcare, finance, and call centres". Its service page lists voice agents for customer service, sales calls, lead qualification and surveys, with CRM, ERP and helpdesk integrations and a fallback to human agents. It names four sectors: retail and ecommerce, health care, contact centers, and banking and finance. See Intellectyx AI voice agent services.
Master of Code Global describes itself as an "AI consulting-led engineering partner for mid-market and large companies". Its voice page offers "AI voice bot solutions for banking, insurance, automotive, and more" and sets out six steps, from discovery and voice design through to deployment and ongoing support. See Master of Code Global voice bot solutions.
Appinventiv lists eight voice agent services on its page, including voice strategy consulting, custom AI voice agent development, multilingual voice adaptation and system integration. It names nine industries, among them healthcare, fintech, lending and ecommerce, and says it is trusted by conglomerates, enterprises and startups. See Appinventiv AI voice agent development.
For a business that wants one call job built into its own systems
RaftLabs builds "AI voice agents that answer and place calls, handle interruptions, confirm critical details, and hand off to people with context". Its page advises starting with one repeated call type and a clear completed result, and says the first paid phase may prove the difficult turns, connect one system, or release one controlled call type. See RaftLabs AI voice agents.
FactoryJet, the publisher of this page, designs, builds, implements and supports custom AI receptionists and AI voice agents. Its service pages describe an agent built inside the phone system and CRM a business already runs. The agent answers calls around the clock, qualifies the caller, books the job, writes the call summary and passes the caller to a person with the notes attached. The client owns what is built. It suits a small office or a call center whose calls depend on its own systems. See FactoryJet AI receptionist and FactoryJet AI call center agents.

Buy a product or have one built
| A ready-made product fits | when your calls are standard and your booking software is mainstream. Goodcall or RingCentral AI Receptionist will be live sooner than a custom build. |
|---|---|
| A custom build fits | when the calls depend on your own systems. The usual signs are an intake process a product cannot follow, software it does not connect to, a job that spans several tools and must stay consistent across them, or a call center queue with a team of agents behind it. |
FactoryJet builds for that second case. We design, build, implement and support the agent, and you own it. We quote the build, and any support you choose, as fixed prices in writing after a short scoping call, and we can keep managing the servers, AI, APIs and maintenance so your team does not have to. We show working software on your own data before a contract. The scope for a small office is on our AI receptionist page. For a team of agents and a call queue, see AI call center agents.
Five questions before you buy anything
| What is the published price at my call volume, in writing, including extra calls or minutes? | The headline rate and the bill are often different numbers. |
|---|---|
| What happens when the AI cannot handle the call? | Ask to hear the handoff to a person. |
| Which of my systems does it write into, and have you made that exact connection before? | An agent that cannot write to your scheduler creates a second inbox. |
| How long do you keep call records, and will you sign a business associate agreement if I need one? | Ask before you need it. |
| Can I hear a recording of it handling a call like mine? | Two minutes of audio tells you more than a price table. |

How this list was made
Every price and company description on this page was read on that company's own site on 11 October 2026. Prices are quoted as published, in the vendor's own units. Where the pages we read carried no price, the entry carries none.
We first read the eight product price pages on 7 September 2026 and read them again on 11 October 2026, which is how we know at least three of them changed. We read them a third time on 21 October 2026, along with Twilio's price list and the build ranges from Groovy Web and Master of Code Global; none of the eight prices had moved. The counts of which companies the AI assistants name come from 14 answers per question, collected on 9 October 2026 from ChatGPT, Claude, Gemini, Perplexity and Google's AI answers.
FactoryJet wrote this list and appears on it among the firms that build custom voice agents. No company paid to appear. FactoryJet sells none of these products and receives nothing if you buy one. Prices in this market change often, so check the vendor's page before you commit. Tell us if a figure here has moved and we will correct it.
