AI voice agents that answer and make calls

Missed calls are missed revenue. A voice agent picks up every call, understands what the caller wants, books or answers on the spot and transfers to your team when a person is needed.

What is an AI voice agent?

An AI voice agent is a phone assistant that combines speech recognition, a language model and natural text to speech to hold real conversations. It can answer inbound calls, book appointments, answer common questions, run reminder or feedback calls and transfer to a human with a summary.

What our ai voice agent development covers

Voice bots that answer calls, book appointments and make reminder calls in natural speech.

Inbound call answering

Every call answered instantly, day and night, with no hold queue.

Appointment booking

Live calendar checks and confirmations by SMS or WhatsApp.

Outbound reminders

Payment, appointment and renewal reminders with response capture.

Lead qualification

Asks your qualifying questions and routes hot leads to sales.

Indian languages

English, Hindi and Bengali voices with mixed language understanding.

Call summaries

Transcripts, intent tags and outcomes pushed to your CRM.

How we approach ai voice agent development

Traditional IVR menus frustrate callers. A voice agent lets them simply say what they need, in their own language.

We script the agent around your real call recordings, set strict boundaries on what it may say and record every call summary for review.

Every project starts with a short discovery call and ends with software you own: source code, data, cloud accounts and documentation are handed over in your name.

Questions about ai voice agent development

Will callers know they are speaking to AI?

We recommend the agent introduces itself as an automated assistant. It is honest and callers accept it when the service is fast and helpful.

Can it use our existing phone number?

Yes, calls can be forwarded from your current number or routed through a new virtual number.

What happens when the AI cannot help?

It transfers the caller to a staff member or schedules a callback, along with a written summary of the call.

Do you work only in Kolkata?

Our engineering team is based in New Town, Kolkata, and we work with clients across West Bengal, the rest of India and overseas. Most projects run remotely with weekly demos, and we meet in person when it helps.
