**An AI voice agent should mostly talk, but a few steps work better with a keypad press.** Long numbers
(order IDs, account numbers, pincodes) are easier to type than to say; "press 1 to confirm" is quicker on a
noisy line; and some callers simply prefer pressing a key. Edesy agents accept keypad (DTMF) input
alongside speech. Here's when to use it, when not to, and how to phrase it.

## When keypad beats speech

| Situation | Why keypad |
|---|---|
| Order ID, account or consumer number | Long digit strings are misheard in speech |
| Pincode | Six digits, exact |
| Quick confirmation ("press 1") | Fast, works on noisy lines |
| Noisy environments | Markets, roads, factories |
| Callers uncomfortable talking to AI | Pressing a key feels easier |

## When not to use it

- **Never for PINs, passwords, OTPs or card numbers.** Don't collect sensitive credentials on calls.
- **Not for open answers** (reasons, feedback, addresses); speech handles those better.
- **Not as a menu tree.** If every step is "press 1, press 2", you've rebuilt an IVR.

## How to phrase it

> Aap apna order number bol sakte hain, ya keypad par type karke # dabayein.

> Order confirm karne ke liye 1 dabayein, cancel karne ke liye 2.

Always offer **speech or keypad**, not keypad only, unless the step truly needs exact digits.

## Examples

- **COD confirmation:** "press 1 to confirm" as a backup to spoken yes. See
  [COD confirmation: AI call vs WhatsApp vs IVR](https://edesy.in/blog/cod-confirmation-ai-call-vs-whatsapp-vs-ivr-2026).
- **Order status:** type the order ID for a lookup. See
  [AI Flow vs prompt agent](https://edesy.in/blog/ai-flow-vs-prompt-voice-agent-when-to-use-2026).
- **Survey on a noisy line:** "rate 1 to 5 on your keypad".

## Read it back

After a keypad entry, read the number back in groups ("four five six, seven eight nine, sahi hai?") and
allow correction. See [pronunciation of numbers](https://edesy.in/blog/ai-voice-agent-pronunciation-numbers-acronyms-india-2026).

and add a "press 1 to confirm" step to your agent, then test it on a noisy street.

## Frequently Asked Questions

### Can an AI voice agent accept keypad (DTMF) input?

Yes. Edesy agents can accept keypad presses during a call, so callers can press 1 to confirm or type a number such as an order ID, alongside normal speech.

### When is keypad input better than speech?

For long numbers (order IDs, account numbers, pincodes), on noisy lines, for a quick yes/no confirmation, and for callers who prefer pressing keys over speaking to a machine.

### Should callers ever enter PINs or OTPs?

No. Never ask callers to enter passwords, PINs, OTPs or card numbers. Use keypad input for non-sensitive data like order numbers or confirmations.

### Can a call mix speech and keypad?

Yes. Let callers speak naturally, and offer keypad input for specific steps: 'You can say your order number or type it on your keypad.'

### Is this the same as an IVR?

No. An IVR is menu-driven and keypad-only. An AI voice agent converses naturally and uses keypad input only where it helps.
