AI voice agent companies in India.
Thirteen platforms side by side, Kallix included.

We make Kallix, one of the AI voice agent companies in India on this list. That's why it comes first, marked "this is us", with its limits spelt out as plainly as anyone else's. The other 12 companies are here because they sell AI agents for phone calls and either focus on India or publish Indian languages, numbers or rupee prices. Every fact about them comes from their own websites, pricing pages and docs, read on 23 October 2026.

Use this guide to see what these companies do, what to check before you pick one, and where each fits. It isn't a ranking, and no company here is called the best, ours included.

What an AI voice agent company does

An AI voice agent handles phone calls on its own, answering incoming ones and placing outgoing ones. It listens to the caller (speech recognition), works out the next thing to say from your script and knowledge (a language model), replies in a natural-sounding voice, and acts on the result. It might book a slot, update your CRM, send a WhatsApp message or hand the call to a person.

An AI voice agent company sells the parts that make this work on real calls. They don't all sell the same thing:

• Self-serve platforms. You sign up, build an agent in a studio or through an API, connect a number and start calling, paying per minute. Kallix, Bolna, Ringg and Sarvam work this way, as do the global platforms ElevenLabs, Retell and Smallest.ai.
• Model makers. Some companies build their own speech and language models and sell them as APIs as well as agents. Sarvam, Gnani, Smallest.ai and ElevenLabs all do.
• Enterprise suites. Haptik, Verloop and Yellow.ai sell voice as part of a wider customer-service platform with chat and WhatsApp, usually through a sales team and a proof of concept.
• Managed programmes. SquadStack and Skit.ai shape the calling programme with you, from setup to pilot, and price on request.

An AI voice agent isn't an IVR menu ("press 1 for sales") or an auto-dialler that plays a recording. It holds a two-way conversation, follows the caller who switches from Hindi to English, and records a clear outcome for every call.

AI voice agent companies in India compared

Checked on 23 October 2026. Prices exclude GST and other taxes. "On request" means the company's public pages give no price. Languages are as each company publishes them, so a count with no names means the company didn't name them on the pages we read.

How we built this list

• Who's in. Companies that sell AI voice agents for inbound or outbound phone calls and show a clear link to India on their own pages: an Indian office, Indian languages, Indian numbers or rupee prices.
• Where the facts come from. Each company's public website, pricing page or documentation, checked on 23 October 2026 and listed under Sources. Where a page didn't say something, we've written "not published" rather than guess.
• Claims are theirs. Language counts, certifications and similar claims are each company's own. We haven't audited them, so ask for proof, such as the audit report, before you rely on one.
• Order. Kallix first, because it's ours. Then three groups: self-serve platforms focused on India, enterprise and managed platforms, and global platforms used in India. Within each group, companies are in alphabetical order.
• Left out. Vapi and Bland are popular global voice agent platforms, but their pricing and home pages didn't mention India, Indian numbers or Indian languages by name when we checked. We've also left out large contact-centre suites that sell AI as one feature among many. Compare Kallix with other platforms →
• Prices change. Treat every rate here as a starting point and confirm it before you sign.

Kallix: this is us

We make Kallix, so weigh this entry with that in mind.

Kallix is a voice AI platform for India's phone-first businesses. Teams build, test, launch, measure and improve AI agents that make and answer phone calls in Hindi, English, Hinglish and more, with WhatsApp follow-ups, CRM sync and analytics built in.

• Best for: sales, collections, operations and support teams at Indian businesses that want one rupee rate, Indian numbers through one partner, and a studio they can run without engineers. A REST API and signed webhooks cover the developer side. Agent studio →
• Pricing: ₹4.80 a minute, billed in 30-second pulses (₹2.40 a pulse). The rate covers everything a call uses except GST: the voice, speech recognition, the language model and Indian call minutes. Two concurrent calls are included, then ₹999 a month for each extra line. Numbers start at ₹499 a month, billed every three months. You get ₹500 in free credits on sign-up, about 100 minutes. See pricing →
• Telephony: Indian numbers through our telephony partner, Vobiz: 140-series for promotional calls, 1600 and 1601-series for service and transactional calls (issued in your business's name), and regional numbers for inbound lines. Kallix declares A2P calling for the numbers it provides, whitelists your numbers with Truecaller and the telecom operators for you, and checks every number against DND (NCPR) before a campaign dials.
• Testing: test suites of scenarios with a pass or fail for each, rerun against every new agent version before it goes live. Testing and evals →
• Data and disclosure: call data is stored and processed in India. Kallix is DPDP Act compliant and acts as your data processor, with a data processing agreement on request. Every agent says it's an AI in its first line and offers a person on request. How we handle data →

Our limits, plainly:

• No bring-your-own carrier or SIP trunk. Calls run on Vobiz numbers only. If you need to keep your Exotel or Twilio lines, Bolna, Ringg or Retell will suit you better.
• No security certifications. We don't hold SOC 2 or ISO 27001. We encrypt data in transit and at rest and give your team role-based access, but if procurement needs an audit report, several companies below say they have one.
• Languages: Hindi, English, Hinglish and more. We don't publish a full list yet. If your callers speak Tamil, Malayalam or Bengali, test those calls with us first and compare the published lists below.
• Fewer lines included. Two concurrent calls come with the base price. Retell and Smallest.ai include 20, so large campaigns can cost more in lines on Kallix.
• No model choice and no on-premise. One stack, chosen and tuned by us and priced into the rate. You can't bring your own model keys or host Kallix yourself.
• New. Kallix was founded in 2026 in Noida, so we don't have the years of track record or the published customer stories that older companies here do.

Self-serve platforms focused on India

These three let you sign up online, build an agent and start calling, and each shows rupee prices on its pricing page.

Bolna

Bolna is a voice agent platform aimed at India, with a no-code studio and an API. Developers can choose the speech, language and voice models an agent uses, or plug in their own API keys.

• Best for: teams with developers who want control over models and carriers, or who need a wide spread of Indian languages.
• Pricing: $0.06 a minute (shown as ₹5.52) on standard top-ups, falling to about 4.5¢ (₹4.15) on the largest. Telephony and a platform fee are added per minute, with no single published figure. New accounts get $5 in free credits, and pilot plans cost $300 for 6,500 minutes or $500 for 12,000 minutes. Numbers cost $5 a month.
• Languages and numbers: 18 languages in its docs, 11 of them with mid-call switching: Bengali, English, Gujarati, Hindi, Kannada, Malayalam, Marathi, Punjabi, Tamil, Telugu and Urdu. Indian numbers come through Plivo or Vobiz after KYC, and it works with Twilio and SIP trunks.
• Worth knowing: data sits in the US by default, and India data residency is an enterprise feature; its home page also lists on-premise deployment. Dollar pricing with separate telephony and platform fees means you'll need a quote to know your all-in rate.

Ringg

Ringg, a Bengaluru company, sells AI agents that work across phone calls, chat, WhatsApp and the web, so one agent can serve more than one channel.

• Best for: teams that want a no-code, self-serve start and expect to add WhatsApp or web chat agents alongside calls.
• Pricing: ₹6 per connected minute on its pay-as-you-go plan, covering speech recognition, the voice, the language model, telephony and basic analytics. Numbers cost ₹499 a month and advanced analytics ₹2 a call. Pricing rests on usage plus a monthly minimum commitment, whose amount isn't published. Free credits come with a new account; enterprise rates are on request.
• Languages and numbers: "20+ languages", not named on its home page. Ringg supplies numbers, or you connect your own telephony (Exotel, Plivo, Twilio, Ozonetel, Vobiz, Tata Tele and others) or a SIP trunk.
• Worth knowing: more carrier choice than Kallix, and chat and WhatsApp agents as well as voice. Ask for the monthly minimum before you compare its per-minute rate.

Sarvam

Sarvam, based in Bengaluru, builds AI models for Indian languages and runs a voice agent platform on top of them. It says the platform is developed and operated entirely in India.

• Best for: teams that want Indian-built speech and language models at a low published rate, with private-cloud or on-premise options for later.
• Pricing: pay-as-you-go calls start at ₹3.50 a minute, or ₹3.00 on its Business plan, with the models included. Add-ons are priced separately and enterprise pricing is custom. New accounts get free credits.
• Languages and numbers: "all major Indian languages", naming Bengali, Gujarati, Hindi, Kannada, Malayalam, Marathi, Punjabi, Tamil and Telugu. You can rent a number after KYC or bring your own provider.
• Worth knowing: says it holds ISO 27001 certification and a SOC 2 Type II report. Its voice agent page doesn't say whether telephony sits inside the per-minute rate, so ask.

Enterprise and managed platforms

These companies sell mainly through a sales team, a demo or a pilot, and none of them publishes a voice agent price. Each has an office in India or names Indian languages on its own pages.

Gnani

Gnani builds its own models for speech recognition, speech synthesis and language, and sells voice agents, call analytics, voice biometrics and agent-assist tools to large organisations.

• Best for: banks, insurers, healthcare, telecom and government bodies that need private-cloud, on-premise or air-gapped deployment.
• Pricing: not published. You start with a demo.
• Languages and numbers: "40+ languages and dialects", naming Bengali, Gujarati, Hindi, Kannada, Malayalam, Marathi, Punjabi, Tamil and Telugu. Telephony details aren't on its home page.
• Worth knowing: says it holds SOC 2 and ISO 27001 certifications and that its deployments meet RBI and IRDAI data-residency requirements. Expect an enterprise sales process rather than a same-day start.

Haptik

Haptik, part of Jio Haptik Technologies Limited with an office in Mumbai, sells conversational AI agents for WhatsApp, RCS, Instagram, Messenger, the web and phone calls.

• Best for: large consumer brands that want WhatsApp, web chat and voice agents from one vendor.
• Pricing: not published. It offers a demo and an ROI calculator.
• Languages and numbers: "100+ languages", with no Indian languages named on its home page. Telephony details aren't published there either.
• Worth knowing: lists ISO, GDPR, CCPA and other compliance claims, independently audited according to its site. Voice is one channel of several, so check its outbound calling features, such as campaigns, DND checks and Indian number series, against your plans.

Skit.ai

Skit.ai sells an AI debt-collection platform: voice agents for outbound and inbound calls, plus SMS, email and chat. It lists offices in New York and Bengaluru.

• Best for: lenders and collection agencies that want a product built only for collections.
• Pricing: not published. One of its case studies mentions performance-based pricing. It says pilots run 30 to 60 days and going live typically takes four to six weeks.
• Languages and numbers: Hindi and English, with regional languages it doesn't name. Telephony details aren't published.
• Worth knowing: its site is built around US collection rules (FDCPA, TCPA and Reg F), and it also shows case studies from Indian banks. For Indian accounts, ask how it applies RBI's rules on recovery calls, such as the 8 am to 7 pm window.

SquadStack

SquadStack, based in Noida, sells voice AI agents for sales, collections, hiring and support, with handoff to people and quality audits. It says it has run AI-native sales contact centres for large Indian consumer brands for six years.

• Best for: large consumer brands, in sectors such as lending, insurance, education and e-commerce, that want a managed sales-calling programme rather than a tool to run themselves.
• Pricing: per minute of live calls, quoted after a discovery call, with a one-off setup charge per use case. It says the dialler and telephony are included.
• Languages and numbers: nine languages, named: Bengali, English, Gujarati, Hindi, Kannada, Malayalam, Marathi, Tamil and Telugu.
• Worth knowing: claims ISO 27001, ISO 27701 and SOC 2 Type II certification, says it complies with the DPDP Act and TRAI's rules, and runs its models in India. Engagements start with a pilot, not a self-serve sign-up.

Verloop

Verloop, a Bengaluru customer-experience company, sells voice AI agents for inbound and outbound calls alongside chat.

• Best for: enterprise sales and support teams with high call volumes that want a proof of concept before they commit.
• Pricing: not published. It offers a free proof of concept.
• Languages and numbers: "10+ Indian languages", naming Bengali, Gujarati, Hindi, Hinglish, Kannada, Marathi, Tamil and Telugu, and 80+ languages in all. It plugs into the PBX, IVR, ACD or cloud telephony you already use, or can lease a calling line for you.
• Worth knowing: working with the telephony you already run suits existing contact centres. There's no self-serve price to compare against.

Yellow.ai

Yellow.ai began in 2016 as Yellow Messenger and has an office in Bengaluru. It sells an enterprise AI platform for customer and employee service across voice, chat and email; its voice agent product is called Nexus VOX.

• Best for: large enterprises that want one vendor for voice, chat and email, connected to contact-centre and CRM tools such as Genesys, NICE, Salesforce and Zendesk.
• Pricing: voice pricing isn't published. There's a free plan for chat, and enterprise pricing goes through sales.
• Languages and numbers: "500+ languages" for voice agents, with no Indian languages named on its home page.
• Worth knowing: claims SOC 2 Type II, ISO 27001, ISO 27701, HIPAA and PCI-DSS. It's a broad suite, which may be more than a team that only needs outbound calls wants to buy.

Global platforms used in India

These platforms sell worldwide, price in US dollars and publish Indian languages in their docs. Indian calls run through a carrier such as Twilio or Telnyx, or your own SIP trunk, so check who registers the numbers and files the A2P declaration.

ElevenLabs

ElevenLabs makes speech and voice models and sells ElevenAgents, a platform for voice and chat agents on the phone, the web and in apps.

• Best for: teams that want a library of more than 16,000 voices and a no-code builder, and are happy to pay in dollars.
• Pricing: plans run from Free (15 minutes a month) through Starter ($6), Creator ($22), Pro ($99) and Scale ($299) to Business ($990 a month, with 12,375 minutes). Extra minutes cost $0.08, and language-model usage is billed separately. Telephony is included, but your own Twilio account or SIP carrier bills you directly.
• Languages and numbers: 90+ languages. Its Eleven v3 model lists 12 Indian languages: Assamese, Bengali, Gujarati, Hindi, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu and Urdu. Its Multilingual v2 and Flash v2.5 models list only Hindi and Tamil, so the model you choose matters. Calls connect through Twilio or a SIP trunk.
• Worth knowing: offers India data residency on enterprise plans and lists SOC 2 Type II, ISO 27001 and other certifications. Its pages don't mention Indian numbers, so plan the carrier side yourself.

Retell

Retell AI is a global voice agent platform with a drag-and-drop builder, APIs, and tools to simulate calls and turn real calls into tests.

• Best for: teams with developers or an existing carrier contract that want detailed testing tools and plenty of included lines.
• Pricing: $0.07 to $0.31 a minute, depending on the language model. The voice engine is $0.055 a minute and Retell's telephony $0.015, with no charge over your own SIP trunk. New accounts get $10 in free credits; 20 concurrent calls are included, then $8 a month for each; there's no platform fee.
• Languages and numbers: its docs list Hindi, Kannada, Marathi, Tamil and Urdu, plus Indian English. Its telephony country list includes India through Twilio or Telnyx, and any carrier can connect over SIP.
• Worth knowing: lists ISO 27001, SOC 2 Type II, GDPR and HIPAA among its compliance claims. Bengali, Gujarati, Malayalam, Punjabi and Telugu weren't in its language list when we checked.

Smallest.ai

Smallest.ai, headquartered in San Francisco according to its site, makes speech models, Lightning for synthesis and Pulse for recognition, and a voice agent platform with a visual builder and APIs.

• Best for: developer teams that want to pick models and pay for each part of the stack.
• Pricing: $0.09 to $0.21 a minute on its pay-as-you-go plan, depending on the models; enterprise from $0.05 a minute. New accounts get $10 in free credits, 20 concurrent calls are included, numbers cost $10 a month, and your own telephony is billed at cost.
• Languages and numbers: its text-to-speech docs list 10 Indian languages: Bengali, Gujarati, Hindi, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil and Telugu. It supplies numbers or connects your carrier over SIP; its pricing page doesn't mention Indian numbers.
• Worth knowing: claims ISO 27001, SOC 2 Type 2 and HIPAA, and lists an on-premise option. Model-by-model pricing gives you control, but makes the monthly bill harder to predict.

How to choose an AI voice agent company in India

Six things decide whether a platform will work on Indian phone calls. Check them in this order.

Indian languages, accents and Hinglish

Most Indian callers mix languages. A customer in Pune might start in Marathi, move to Hindi and finish in English. Ask each company:

• Which languages does it publish by name, not just as a count?
• Can the agent switch when the caller switches, mid-sentence as well as mid-call?
• Can you hear sample calls in your callers' language before you pay?

A figure such as "100+ languages" tells you little about how an agent handles a strong regional accent on a noisy line. Bolna, Gnani, Sarvam, SquadStack and Verloop name their Indian languages; the table above shows what each company publishes.

Indian telephony and number series

An agent is only as good as the line it calls on. Under TRAI's rules, promotional calls go out on 140-series numbers, while the 1600 and 1601 series are kept for service and transactional calls. Since TRAI's February 2025 amendment, telemarketing from ordinary 10-digit numbers isn't allowed. The amendment TRAI introduced on 18 September 2026 adds that calls placed by software, AI agents included, are A2P calls that must be declared to the telecom operator in advance, with the caller IDs they'll use.

Ask each company:

• Does it supply Indian numbers, or do you bring your own carrier or SIP trunk?
• Which number series can it provide, and who files the A2P declaration?
• What happens when one of your caller IDs gets flagged as spam?

Compliance: TRAI, DND and DPDP

• DND. Promotional calls must respect the National Customer Preference Register (NCPR), better known as DND. Ask whether numbers are checked before a campaign dials.
• Calling hours. Lenders' recovery calls must fall between 8 am and 7 pm, under RBI's rules. Check that you can set calling windows in IST.
• DPDP Act. You need a lawful basis, usually consent, to call people and record the call, and withdrawing consent must be easy. The core duties apply from 13 May 2027. The Act doesn't require data to be stored in India, so where your recordings live is the vendor's choice: ask.
• Certifications. Several companies here claim SOC 2 or ISO 27001. If your security team needs one, ask for the report itself.

Pricing model

Per-minute prices look comparable and rarely are. One rate may include speech, the model, the voice and the call itself; another covers the AI only and adds telephony, a platform fee and line charges. The section below sets the published rates side by side.

No-code or developer-first

If sales, collections or support teams will own the agent, look for a studio where they can write the script, add FAQs and run tests without engineers. If developers will own it, look for a full API, webhooks and, if you want it, the freedom to choose models or carriers. Bolna and Smallest.ai let you pick your own models; Kallix, Ringg and Sarvam price the models into one per-minute rate.

Testing and support

Ask how you test an agent before it reaches a customer: browser test calls, simulated conversations, and test suites you can rerun after every change. Then ask what happens after launch: who reviews calls, how quickly support answers, and whether help with your first agents is included or paid.

What a minute really costs

Published rates on 23 October 2026, before GST. Dollar prices move with the exchange rate, and your bank may add a fee on card top-ups.

Gnani, Haptik, Skit.ai, SquadStack, Verloop and Yellow.ai quote on request. SquadStack says its per-minute price includes the dialler and telephony, with a one-off setup charge per use case; Verloop offers a free proof of concept.

Five questions make any two quotes comparable:

1. What does a minute include? Speech recognition, the language model, the voice and the call itself, or only some of them?
2. How are minutes counted? Per second, per 30-second pulse or per connected minute. On 30-second pulses, a 50-second call bills as two pulses.
3. How many calls can run at once, and what does each extra line cost?
4. What else is billed? Number rental, platform fees, setup fees and monthly minimums.
5. What will a month of your calls cost? Ask each vendor to price the same volume, say 10,000 minutes, with numbers and lines included.

Choosing AI calling companies in India by industry

The rules and the calls differ by sector. Here's what to weigh in each.

Banking, lending and NBFCs

Collections and EMI reminders carry the strictest rules. RBI bars recovery calls before 8 am or after 7 pm. A TRAI direction of 19 November 2025 puts banks', financial services firms' and insurers' service calls on 1600-series numbers and their promotional calls on 140-series numbers. Look for calling windows, outcomes such as promise to pay and dispute, and payment links sent on WhatsApp, never card numbers or OTPs taken on the call. Gnani, Skit.ai and SquadStack all list lending or collections among their main uses. Kallix for banking and lending →

Insurance

IRDAI's distance-marketing guidelines (2011) require insurers to record telemarketing calls and tell customers the call is recorded. Insurers' service calls also move to 1600-series numbers under TRAI's direction. Check that every call is recorded and transcribed, and that the opening line can carry the recording notice. Kallix for insurance →

E-commerce and D2C

COD confirmation, abandoned-cart and delivery calls are short, frequent and time-sensitive, so concurrency and per-minute billing matter more than in most sectors. A WhatsApp follow-up often closes the loop. TRAI hasn't named a number series for every kind of e-commerce service call, so ask your provider which series fits your calls and keep its answer in writing. Kallix for e-commerce →

Healthcare and clinics

Appointment booking, reminders and follow-ups involve patients' personal data. Under the DPDP Act you need consent and a clear notice, so check where recordings are stored, how long they're kept and who in your team can see them. Kallix for healthcare →

Education

Admissions teams get enquiry spikes around results and deadlines, so check how many calls can run at once and what extra lines cost. TRAI's 2026 amendment lets a business send commercial communications for seven days after a person's written or digital enquiry, kept in a form that can be checked, which suits quick callbacks to admission forms. Kallix for education →

Real estate

Leads from property portals and ads go cold quickly. Look for fast callbacks, qualifying questions on budget, location and timeline, site-visit booking, and CRM sync with tools such as LeadSquared or Salesforce. Kallix for real estate →

Logistics

Delivery updates and address checks are service calls. TRAI's 1601 series covers service and transactional calls from courier and logistics companies. TRAI allots these numbers to the business itself, so ask your provider to help you get one in your company's name. Kallix for logistics →

Does your city matter?

Not for the product. AI voice agent platforms are cloud software: you sign up or sign a contract online, and calls travel over the national telecom networks. A business in Chennai, Kochi, Surat, Jaipur or Lucknow gets the same platform as one in Mumbai, Delhi NCR or Bengaluru. A company's office location matters only if you want people on site.

What changes by region is language, so match the platform's published languages to your callers first:

• Tamil Nadu and Chennai: Tamil, often mixed with English.
• Kerala and Kochi: Malayalam.
• Karnataka and Bengaluru: Kannada, Hindi and English.
• Telangana, Andhra Pradesh and Hyderabad: Telugu, with Hindi and Urdu in places.
• Maharashtra, Mumbai and Pune: Marathi and Hinglish.
• Gujarat, Ahmedabad and Surat: Gujarati.
• West Bengal and Kolkata: Bengali.
• Delhi NCR, Uttar Pradesh and much of the north: Hindi and Hinglish.

For inbound lines, a regional number helps callers recognise a local business; Kallix provides regional numbers through Vobiz. If your callers need Tamil, Malayalam or Bengali, compare the published lists in the table above and test before you commit, Kallix included.

Run a fair trial before you sign

1. Pick one job, such as EMI reminders or lead qualification, with one script.
2. Split one contact list between two or three platforms, with the same script and the same calling window.
3. Listen to the recordings, not just the dashboards: accents, interruptions, language switches and how each agent ends the call.
4. Compare cost per completed outcome, such as a booked visit or a promise to pay, rather than cost per minute.
5. Check the paperwork: the data processing agreement, where data is stored, who files the A2P declaration, and the notice period.

On Kallix, the ₹500 in free credits covers about 100 minutes of a trial like this. Start with Kallix pricing →
