AI Call Assistant for Business: What It Does, What It Costs and How to Set One Up

An AI call assistant — also called an AI voice agent, AI receptionist or voicebot — is software that answers and makes phone calls in a natural voice. It listens to what the caller says, understands the request, decides what to do and replies out loud, in real time. Unlike an IVR, there is no "press 1 for bookings": the caller just says what they want.

What makes it an assistant rather than a talking FAQ is that it is connected to your business. On Reputoo, the same agent that answers calls also has your services, prices, staff schedules and booking rules, so it can actually do the job — not just take a message.

There are two directions of call:

• Inbound — customers ring your number and the assistant answers. See inbound AI phone agent.
• Outbound — the assistant calls customers for you: reminders, confirmations, follow-ups. See outbound AI calling agent.

A typical inbound call to a clinic, salon or service business runs like this:

1. Answers immediately with your business name, at any hour.
2. Understands the request — a booking, a price, an address, a reschedule — in the caller's language. Reputoo's assistant speaks 36 languages, including Hindi and the major Indian languages, and can switch mid-call.
3. Answers questions from the knowledge you gave it: services, prices, timings, location, policies.
4. Books the appointment into the real schedule — the right staff member, a free slot, the right length of service.
5. Takes a deposit if you want one, by sending a payment link, and confirms the booking when the money clears.
6. Confirms on WhatsApp with the details, and sends a reminder before the appointment. Online consultations get a Google Meet link automatically.
7. Logs the call with what was said and what happened, so your team can check its work.

When a caller asks to speak to a person, the assistant can pass the call to your team's number (a premium option), along with a summary of who is calling and why.

The same assistant can work through a list of calls you would otherwise make by hand:

• Appointment reminders the day before, with the option to confirm or reschedule on the spot.
• New enquiry follow-up — a quick call to people who filled a form but did not reply on WhatsApp, to qualify them and book a call with your team.
• Payment and renewal reminders, with a payment link sent on WhatsApp during the call.
• Check-in and feedback calls after a visit, so unhappy customers reach a person quickly.
• Re-engagement calls to customers who have not been back in a while.

Outbound calls should go only to customers who have a relationship with you and expect to hear from you — the same consent you would want before calling them yourself.

An AI call assistant does not replace the people who build relationships with your customers. It takes the repetitive part — the same twenty questions and the booking — off their hands, and covers the hours nobody is there. More detail in AI vs IVR and AI vs a human receptionist.

• Clinics and dentists — bookings, reschedules, fees and timings while the doctor is with a patient. See AI for clinics.
• Salons and spas — the phone rings while hands are busy; the assistant books the right stylist for the right length of service. See AI for salons.
• Real estate — enquiry calls from ads and portals answered at once, site visits booked. See AI for real estate.
• Restaurants — table bookings and the same questions about timings and location, during the busiest hours. See AI for restaurants.
• Coaching, fitness and services — trial classes, demo bookings and fee questions.

The common thread: a business where calls bring bookings, and where the people who could answer are usually busy doing the work.

On Reputoo you pay a monthly voice add-on and then for the minutes you use:

• Voice add-on: ₹1,999 a month in India, or $29 a month elsewhere, on top of a Reputoo plan.
• Minutes, by voice quality: Clear ₹4 a minute, Studio ₹8 a minute, Signature ₹12 a minute, drawn from a prepaid wallet — so spend never runs past what you loaded.
• Voice Starter Pack: a one-time ₹1,499 that goes entirely into your wallet as call credit — about 375 minutes on the Clear voice.

A quick way to size it: multiply the calls you get in a month by their average length. A business taking 300 calls a month averaging two minutes uses about 600 minutes — ₹2,400 on the Clear voice, plus the add-on. Compare that with the bookings you currently lose to missed calls.

1. Teach it your business. Add your services, prices, timings, location and policies — or point it at your website and price list to start from.
2. Connect your schedule. Add staff, their working hours and how long each service takes, so it only offers slots that really exist.
3. Choose a voice and languages. Pick Clear, Studio or Signature, and the languages your callers speak.
4. Decide the rules. Deposits or pay-at-visit, how far ahead people can book, what it should never promise, and when to pass a call to your team.
5. Test it yourself. Call it, try the awkward questions, and read the transcript. Reputoo can also ring you so you hear it first.
6. Point your calls at it. Forward your number — after hours first if you prefer — and read the call log for the first week.

It is worth being clear about the limits, because they decide how you set it up:

• It only knows what you teach it. If a price, policy or service is not in its knowledge, it should say it will check and pass the question to your team — not guess. Keep the knowledge up to date when prices change.
• It should not give professional advice. A clinic's assistant books the appointment and answers practical questions; diagnosis and treatment advice stay with the doctor. Tell it so in its rules.
• Judgement calls belong to people. Refund disputes, special discounts and complaints are better handed to your team with the call summary attached.
• Bad lines are still bad lines. On a very noisy or weak connection, it may need to ask the caller to repeat — just as a person would.

Set up this way, the assistant handles the routine calls completely and hands the rest over cleanly, which is what most businesses actually need.

Because every call is logged, treat the call log the way you treat your customer records. Let callers know calls may be recorded and handled by an AI assistant — a short line in the greeting does it. Limit who on your team can open recordings and transcripts, and use the details only for the booking or enquiry the caller made. In India, the Digital Personal Data Protection Act, 2023 expects personal data to be used for the purpose it was given; the same common-sense rules apply elsewhere.

Done properly, the log is a benefit to customers too: nobody has to ask them to repeat what they already said, and the person who calls them back knows exactly what they need.

1. Does it book, or only take messages? An assistant that cannot see your schedule just moves the work to tomorrow.
2. Which languages, really? Call it in the language your customers use, with their accents.
3. How is it priced? Per minute, per call or flat — and is there a prepaid limit so a busy month cannot surprise you?
4. Can you read every call? Look for a call log with the transcript, a recording and a summary.
5. What happens after the call? A WhatsApp confirmation and reminder cut no-shows; a payment link turns a booking into revenue.
6. Can a caller reach a person? Ask how the hand-over works when someone insists on a human.
