AI Voice Agents That Answer Every Call, Day or Night
A natural-sounding voice agent that picks up, qualifies leads, and books appointments so your phone never goes to voicemail again.
The problem
We miss customer calls — leads are going to competitors
"Half the people who call us hang up before we pick up — and we have no idea who they were." Every unanswered call is a customer who will dial the next business on Google instead of waiting. After-hours, lunch breaks, busy seasons, and one-person front desks all bleed revenue you never see on a report.
A voice agent that sounds human and works 24/7
AIERAX builds AI voice agents that pick up on the first ring, hold real conversations, and capture every lead in your CRM. They handle bookings, FAQs, quotes, and call routing in your brand voice, in the languages your customers speak. You keep your existing phone number and only pay attention to the calls that actually need a human.
How it works
-
Map your calls
We listen to a week of real call recordings and identify the top reasons people call — bookings, pricing, support, directions — so the agent knows exactly what to handle.
-
Build the conversation
We script the flows, give the agent your tone of voice, and connect it to your calendar, CRM, and WhatsApp so every conversation ends with a logged outcome.
-
Train on your business
The agent learns your services, prices, hours, locations, and edge cases. It can speak English, Tamil, Hindi, or whatever your customers use.
-
Go live on your number
We route your existing phone line through the agent. Calls it can handle are closed; calls it can't are warm-transferred to a human with full context.
-
Tune and report weekly
You get a dashboard of every call, transcripts, and a weekly review where we refine answers and add new flows as your business grows.
A real example
A Chennai dental clinic was getting around 60 inbound calls a day and missing roughly 22 of them — most after 7pm or during procedures. We deployed an AI voice agent that answers in Tamil and English, checks the calendar, and books appointments directly into their existing system. In the first month they captured 480 previously-missed calls, booked 138 extra appointments, and the receptionist got back about 3 hours a day to focus on patients in the chair.
Business outcome
- Never miss a call, even at 2am or during lunch
- Capture every lead directly into your CRM
- Book appointments without a human in the loop
- Speak your customers' language, including Tamil and Hindi
- Cut receptionist workload by 60 to 80 percent
- Keep your existing phone number and setup

Common questions
How much does an AI voice agent cost for a small business?
Most SMB voice agents land between a one-time build fee and a monthly usage fee tied to call minutes. For a typical clinic, salon, or service business, total monthly cost is usually less than a part-time receptionist. We scope your exact numbers after a free call audit.
Will the AI voice agent sound robotic to my customers?
No. We use the latest neural voice models that include natural pauses, breathing, and inflection. Most customers cannot tell they are speaking to an AI, and you can pick a voice that matches your brand — warm, professional, energetic, or local-accented.
Can the voice agent speak Tamil, Hindi, or other Indian languages?
Yes. Our agents handle English, Tamil, Hindi, Telugu, Malayalam, and code-switching between them mid-conversation. This is critical for businesses in Chennai and across India where customers naturally mix languages.
What happens if the AI cannot answer a customer's question?
The agent is built with clear escalation rules. If a caller asks something outside its scope or insists on speaking to a person, it warm-transfers to your team with a summary of the conversation so the human picks up with full context, not a cold start.
Do I need to change my phone number or phone system?
No. We route your existing number through the voice agent using your current telecom provider. To your customers and your staff, nothing about the phone setup looks different — they just get an AI receptionist on the line.
How long does it take to set up a voice agent for my business?
A standard deployment takes two to three weeks from kickoff to go-live. Week one is call audit and scripting, week two is build and integration with your CRM and calendar, and week three is testing with real calls before we cut over.
