# How to reduce appointment no-shows with AI calling

> To cut no-shows, have an AI voice agent call every booked customer a day or two before to confirm, reschedule the ones who cannot make it, and flag cancellations so the slot can be refilled, all in the customer's language. Spoken confirmation calls in Telugu or Hindi beat an English SMS that nobody reads.

## Why calls beat SMS for confirmations

A spoken call in the patient's language gets a real yes or no, lets them rebook on the spot, and surfaces cancellations early. An SMS gets ignored. See [no-show reduction](https://agents.elevatebox.in/glossary/no-show-reduction).

## The flow that works

1. Call 24–48 hours before the appointment
2. Confirm, or rebook to the next open slot
3. Flag cancellations so the slot can be refilled
4. Send the confirmed details on WhatsApp with permission

## What to say on a confirmation call

Keep it short and specific: who is calling, the appointment day and time, and one question, 'Will you be able to come?'. If the answer is no, offer the next two open slots instead of asking for a free choice. If the customer wants to cancel, thank them and release the slot at once so it can go to someone on the waiting list.

## Measure it

- No-show rate: booked appointments where the customer did not come, before and after the calls
- Confirmation rate: share of called customers who said yes
- Rebooked and refilled slots: appointments saved that would have been empty

## Frequently asked questions

### How much can AI confirmation calls reduce no-shows?

Results vary by clinic, but spoken same-language confirmations with easy rebooking consistently recover appointments that SMS reminders miss. Measure your own rate for a month before and after.

### Should the call or the SMS come first?

The call. It gets a real answer and lets the customer rebook on the spot; a WhatsApp message with the confirmed details, sent with permission, then backs it up.
