What the AI calling agent does on an EMI reminder
Prakash Motor Finance, a two-wheeler lender in Pune, loads the week's EMIs. Arushi calls each borrower in Hindi, keeps the English words people use for loans, and answers the number when they call back.
Your team loads the loans due that week, and the agent dials them in batches at the time you schedule. It asks for the borrower by name and says nothing about the loan until the vehicle number checks out.
The agent checks the four digits against your loan system. Only after a match does it read the amount, the due date and the last day of your grace period, all from your records.
A borrower who wants to pay now gets a link from your own payment provider by SMS, with the amount filled in. The agent says out loud that it will never ask for a UPI PIN or an OTP.
When the salary comes in after the due date, the agent asks which day works and accepts any date up to your grace date. A borrower who asks for later hears the grace date instead.
People who miss the reminder often call the number back. Point that number at the same agent and it picks up in Hindi, checks the vehicle number and reads the EMI, the way a front desk would.
With language detection on, a Beta speech setting, the agent follows a borrower from Hindi into English and carries on with the same loan. Detection uses another speech recognition model, so try it on your own calls first.
Hindi calls, and the rules for calling customers in India
Borrowers mix English loan words into Hindi, and Indian telecom and data rules cover who may call them and from which number. These notes point to the official texts.
Hindi and English
Sonic speaks Hindi with English words in the same sentence, and Ink-2, Cartesia's speech recognition model, transcribes Hindi and English. Write your loan terms, such as EMI, foreclosure and NACH, into full sentences and test how borrowers say them.
Hinglish in Sonic (Cartesia docs); Ink-2 languages (Cartesia docs)
Number series (TRAI)
TRAI's July 2026 note says entities regulated by RBI, SEBI, IRDAI or PFRDA use 1600-series numbers for service and transaction calls to existing customers, and that any sector uses 140-series numbers for promotional calls. Customers can block 140-series calls by sector on the DND registry.
Consent and auto-dialers
TRAI's February 2025 amendments to the TCCCPR 2018 limit implied consent for service and transaction calls to the length of the contract, restrict ordinary 10-digit numbers for telemarketing, and bring in disclosure of auto-dialers and robocalls.
Personal data (DPDP)
The Digital Personal Data Protection Rules, 2025 were published on 13 November 2025. As published, the notice rule (Rule 3) and Rules 5 to 16 take effect 18 months after that date. A call recording that identifies a borrower is personal data under the DPDP Act, 2023.
These notes summarize TRAI and MeitY documents; they are not legal advice. Your counsel and your telecom provider can say which number series, consent and notice apply to your calls.

AI calling agent for India FAQs
What is an AI voice calling agent?
An agent that places phone calls from a list and talks to the person who answers. This one calls two-wheeler loan borrowers in Hindi before the EMI date, checks who picked up, and texts a UPI link or writes down the day they will pay.
How much does an AI calling agent cost in India?
Cartesia charges $0.03/min, plus telephony and LLM usage, and bills in US dollars. The ₹ amounts on this page are the lender's EMIs, not Cartesia prices. See pricing.
Can the agent call from an Indian phone number?
Cartesia's own numbers are US only. Bring a Twilio number, or connect an Indian SIP trunk and import its numbers. Ask that provider which series your calls need, 140 or 1600, and what registration under TRAI's rules it handles for you.
How does it work through a list of borrowers?
A developer sends the list through the batch calling API, up to 5,000 numbers per batch, with each borrower's name and EMI as variables and a start time. Unanswered calls can be retried, and voicemail detection ends the call or leaves a message you write.
How do AI voice agents handle Hindi and English on one call?
Ink-2 transcribes both. An agent set to Hindi keeps Hindi, with English words where borrowers use them. To follow a borrower who moves fully into English, turn on language detection, a Beta speech setting that covers 10 languages including Hindi and English. It runs on a different recognition model from Ink-2.
Can the sample call switch to English?
No. The sample call stays in Hindi from start to end. Mid-call switching needs language detection, which you can turn on for an agent of your own and test with your borrowers.
Can it work as an AI receptionist in India too?
Yes. Assign the same number to the agent and it answers incoming calls, as in the call-back example above. An inbound line for appointments or service bookings is a separate agent with its own instruction and tools.
Which Indian languages can it speak?
Sonic speaks 10 Indic languages, listed on Cartesia for India. For a two-way call the agent also has to hear the borrower, and Ink-2 transcribes Hindi and English but not the others, so plan Hindi and English calls.
What happens when a borrower disputes the amount?
The agent stops the reminder and transfers the call to the loan officer's number you set. Transfers work on Twilio and SIP trunk numbers.
Does Cartesia keep the call recordings?
You choose per agent. An agent-wide setting stops Cartesia from storing transcripts, recordings and caller numbers for that agent. There is no switch for a single call.
