How to Set Up an AI Answering Service for your Business Number

August 29, 2026•2 min read

You have a business number that all your customers know. It's printed on your business cards, your shop sign, and your Google My Business profile. You want to use an AI Receptionist to answer your calls, but you absolutely cannot change your phone number.

The good news? You don't have to. You can easily connect your existing Indian mobile number to an AI Answering Service using a telecom feature called Conditional Call Forwarding.

What is Conditional Call Forwarding?

Unlike standard call forwarding (which blindly sends every call away), Conditional Call Forwarding only triggers under specific circumstances. You can tell your telecom provider to only send the call to the AI if:

  • You do not answer after 30 seconds.
  • Your phone is currently busy (you are on another call).
  • Your phone is switched off or out of coverage area.

Step-by-Step Setup Guide

Setting this up takes literally 60 seconds directly from your phone's keypad. No apps required.

  1. Get your AI Number: First, sign up for a platform like CallAgent AI. You will be assigned a unique virtual number for your AI brain (e.g., a specific Vapi or Exotel number).
  2. Open your Dialer: On the phone that holds your main business SIM card, open the regular phone dialer app.
  3. Dial the Code: Type the telecom code for conditional forwarding, followed by your new AI number, and press dial.
    For example, on most Indian networks, to forward calls when you don't answer, you dial:
    **61*YOUR_AI_NUMBER#
  4. Confirmation: You will see a popup on your screen saying "Call Forwarding Registration was Successful."

The Result

Now, your phone rings exactly like normal. If you are free, you answer the call yourself! But if you are busy with a client, or if it is 2:00 AM and you are asleep, the call quietly routes to your AI Receptionist. The AI answers politely, captures the lead, and sends you a WhatsApp summary instantly.
