AI Missed Call Callback
A missed call callback with an AI voice agent means that when someone gives a missed call to your number, they are called back within seconds by an agent that talks to them, finds out what they need and books the next step. Your missed-call service provider sends each missed call to Outpero's webhook, which triggers an instant outbound call; Outpero's inbound answering can also pick up calls on your number directly.
* Time from the lead reaching Outpero to the first ring, under normal conditions. It depends on how quickly your lead source delivers the lead.

Why missed call callback breaks when people do it
Missed-call campaigns are popular in India because they cost the customer nothing, but most businesses treat the missed-call log as a to-do list someone works through at the end of the day. By then the person who gave a missed call after seeing a newspaper ad or a hoarding has forgotten why, or ignores an unknown number. Many setups just reply with an SMS, which cannot deal with a single question.
Step by step
How it works
- 01Keep your existing missed-call number with your telephony provider, and set it to post each missed call (caller number and campaign) to Outpero's webhook, directly or via Zapier or Make.
- 02Outpero dials the caller back within 30 seconds, while they still remember giving the missed call.
- 03The agent mentions the campaign they responded to, such as the hoarding, newspaper ad or product pack, and asks what they are interested in.
- 04It qualifies the caller, books an appointment, visit or demo in your calendar, and sends details on WhatsApp.
- 05Every callback's recording, transcript and fields go to your dashboard and webhook; unanswered callbacks retry on your schedule.

A sample missed call callback call
Callback to a missed call received 20 seconds ago on a number printed on a hoarding for a free health check-up camp in Kukatpally, Hyderabad. · Runs in Telugu with English words; shown here in English.
- Outpero AINamaste, this is the AI assistant of Care Plus Hospital. You just gave a missed call to our number. Did you want to know about the free health check-up camp?

- Outpero AICare Plus Hospital, Kukatpally. The number was on our hoarding for the free check-up camp, so I am calling to give you the details. Is this a good time?

How the trigger reaches Outpero
| Where it comes from | How it gets to the agent |
|---|---|
| Telephony provider missed-call number | Your existing missed-call number is set to post each missed call, with caller number and campaign, to Outpero's webhook, directly or through Zapier or Make. |
| Hoarding and print campaign numbers | Give each hoarding or newspaper ad its own missed-call number, so the webhook payload names the source and the agent opens with it. |
| Product pack or QR campaigns | A different missed-call number on the pack or the leaflet sends a different campaign tag in the webhook, so FMCG or agri teams can see which pack produced which callback. |
| Lead log sheet | Callback outcomes and captured fields go to a live Google Sheet or the CRM by webhook, and missed calls that go unanswered retry on your schedule. |
| Hospital or clinic booking calendar | Appointments booked on the call are written to the connected calendar so the front desk sees the slot without any manual entry. |
Results go back out the same way: a webhook you provide, or a live spreadsheet or API call mid-call. WhatsApp messages and calendar bookings are opt-in per employee.

What to track — and what goes wrong
| Track | How to read it |
|---|---|
| Callback answer rate | If many callbacks go unanswered, check the delay between the missed call and the callback; the faster it comes, the more people remember. |
| Appointments or visits booked per answered callback | Low conversion with high answer rate means the campaign promise and the offer do not match what callers expect. |
| Source split by campaign number | Compare booked visits by hoarding, pack or newspaper number to see which medium deserves more of the budget. |
| Wrong number and accidental missed calls | A high share points to a number that is easily misdialled or a QR code placed badly, not to a weak callback. |
- !Using one missed-call number for every campaign, so the agent cannot say what the person responded to.
- !Delaying the callback. After a few minutes the caller has moved on and often does not answer the unknown number.
- !Letting the agent give medical advice. It shares camp details and booking only; clinical questions go to the hospital team.
- !Not setting retries. People miss the first callback, so a second attempt later in the day recovers a good share.
If the missed-call number is not tied to any campaign and callers do not expect a callback, the call can feel intrusive. Urgent medical enquiries should reach a person directly and not wait for a callback.
Questions people ask
Does Outpero pick up calls on my business number?
+
Yes, inbound answering is live, and it can pick up calls to your business number. Missed call callback is the outbound alternative: your missed-call provider logs the missed call and sends it to Outpero's webhook, and Outpero immediately places an outbound call back to that number. For the customer the experience is close to being picked up, because the callback arrives within about 30 seconds.
Which missed-call providers work with this setup?
+
Any provider that can send a webhook or API notification for each missed call, or that can be connected through Zapier or Make. Most Indian cloud telephony and missed-call services offer this as a call notification or webhook URL setting on the number. The payload only needs the caller's number; a campaign or keyword field helps the agent open the conversation with the right context.
Is it fine to call back someone who gave a missed call?
+
A missed call to a campaign number is the customer asking to be contacted, so a prompt callback about that campaign is generally treated as a response to their own action. Keep the call relevant to what they responded to, use a registered line and keep a record of the trigger. Outpero calls from a DLT-registered line and logs the triggering missed call alongside the callback recording.
What if the caller does not pick up the callback?
+
The agent retries on the schedule you set, for example after 15 minutes, then a few hours later, then the next morning within your calling window. People who give a missed call are often in the middle of something, so a second attempt picks up a meaningful share of them. Unanswered attempts are not billed, since you pay only for connected talk time.
Why use a missed call number at all instead of a form?
+
Because many customers, especially outside the metros, prefer a missed call to filling a form or typing in English. It costs them nothing, works on any feature phone and suits print, radio, hoardings and product packaging. Pairing it with an instant AI callback in Hindi, Marathi, Tamil, Telugu, Kannada, Malayalam or Indian English keeps that low-friction entry and adds a real conversation.
How much does an AI voice agent for missed call callback cost?
+
Outpero has no setup fee and no monthly base fee — you pay only for connected talk time, from ₹5 per minute (1 credit = ₹1, credits never expire), plus ₹649/month for a dedicated calling number. You pay only for the minutes the agent is actually talking. Prices exclude 18% GST.
