On plans with calls, Kiko answers voice calls to your WhatsApp Business number. It talks naturally, answers from the same knowledge as your chat, books appointments during the call, and when a caller asks for a person it flags the call for your team to follow up on WhatsApp.

## How setup works

1. **Connect WhatsApp**: Calls come to the same WhatsApp Business number your customers already message.
2. **Choose a voice and hours**: Pick Kiko's voice and when it answers, under Channels › Voice calls.
3. **Take the first call**: Make a test call from the playground, then let customers call. Every call is saved in their chat.

Included in every plan, from $29 a month, after a 14-day free trial.

## What Kiko does on a call

- **Answers from your knowledge**: The same pages, files and products as your chat.
- **Books during the call**: Offers open times and confirms the booking before the caller hangs up.
- **Flags calls for a person**: When a caller asks for someone, Kiko flags the call for your team to follow up on WhatsApp, and it shows as a call-back.
- **Sends a WhatsApp message**: Can follow up in the chat with a link or the details discussed.
- **Every call saved**: What was said is kept in the customer's normal WhatsApp chat.
- **Calls back on request**: Your team can call customers back from HeyKiko when they've agreed to it.

## Good to know

- **WhatsApp calls, not phone lines**: Kiko answers calls made through WhatsApp to your business number. It doesn't answer regular phone numbers.
- **Billed per started minute**: Calls use AI credits for each minute started, from the same balance as chat; there's no separate voice bill.
- **Calls at the same time**: How many calls Kiko can take at once depends on your plan; see the plan table on the pricing page.

## Questions about the WhatsApp AI voice agent

### Can an AI answer WhatsApp calls?

Yes. Kiko answers voice calls to your WhatsApp Business number on plans with calls, using your own knowledge, and can book appointments or flag the call for your team to follow up.

### Does Kiko answer my regular phone line?

No. Kiko answers calls made through WhatsApp to your business number, not regular phone lines.

### How are voice calls billed?

Each started minute uses AI credits from your plan's balance. Calls that fail or aren't answered are refunded.

### Can the caller speak to a person?

Not on the same call: there's no live transfer. When a caller asks for a person, Kiko flags the call for your team, who follow up on WhatsApp, and it appears as a call-back, as missed calls do.
