Voice AI in India

What is an AI voice agent used for in India?

Answering and making the calls a team would otherwise make by hand: enquiries, appointment bookings, payment and renewal reminders, lead qualification and follow-ups — each in the language the customer speaks.

  • Inbound: every call answered, questions answered from your website and documents, bookings made through Cal.com or your own system.
  • Outbound campaigns with pacing, smart retry, voicemail detection, callback scheduling and A/B-tested opening lines.
  • One agent across phone, WhatsApp, website chat and Telegram, with one memory of each customer. More on the voice AI agent page.

Indian languages

Which Indian languages does the voice agent speak?

All 22 scheduled Indian languages plus English, with Hinglish code-switching — a caller can mix Hindi and English in one sentence and be understood. WhatsApp and website chat replies cover all 22 as well.

Each language has its own page with sample conversations and use cases. Browse them all on Indian languages or the solutions index.

Phone numbers

Can I get an Indian phone number?

Yes. Buy an Indian number inside the platform, or import one you already hold on Plivo, Vobiz, Twilio or Telnyx.

  • Transfer to a person and voicemail detection work on numbers bought in the platform and on Plivo and Telnyx numbers. An imported Twilio number answers and records, but can't transfer or detect voicemail.
  • Telnyx calls only the countries switched on in your outbound voice profile, so add India before making outbound calls.
  • One agent can call out from numbers on several providers and pick per call.

Calling hours

How do I keep calls inside TRAI's calling hours?

Set each campaign's calling hours to 09:00–21:00. Hours are read on the called person's clock, and callbacks and campaign calls wait for them. The platform doesn't impose a window of its own, so the setting is yours.

You remain responsible for the rest of India's telemarketing rules, such as DLT registration where it applies and not calling people who have opted out. We don't scrub numbers against the DND or NCPR registry; the product gives you a do-not-contact list you keep, calling hours and days you set per campaign, and a recording and transcript of every call. Under the DPDP Act, notice and consent for your customers' data are your responsibility too.

WhatsApp Business API

Does it include the WhatsApp Business API in India?

Yes. Connect your number to the official WhatsApp Business API through us — an approved Meta Tech Provider — and run templates, broadcasts, a shared inbox and an AI agent that replies in all 22 Indian languages.

Sign in with Facebook through Embedded Signup, pick the number and you are live in minutes — every WhatsApp feature works inside the platform. WhatsApp charges are Meta's published per-message rates plus our fee, set out on the pricing page. More on the WhatsApp Business API.

Data and billing

Where is data stored, and how is billing done in India?

Indian workspaces store their data in India, in Mumbai. Billing is in Indian rupees by UPI or card, with GST invoices; prices are on the pricing page.

You are placed in the India workspace automatically when you sign up from India. Agencies can resell under their own brand with white label on every paid plan, and their clients pay them through the agency's own Razorpay account.

Industries

Which Indian industries is it built for?

Teams with high call volumes and customers who prefer their own language: lending and collections, D2C brands, real estate, healthcare, insurance, education, logistics and more.

Each industry page covers the call flows, the rules that apply in India and an honest note on where voice AI is the wrong tool. Selling outside India too? See the UK, US and UAE pages.
