# Confirm to answer call

> Use confirmKey and confirmSound on the Vobiz Dial element to require human confirmation, preventing voicemail systems from accidentally answering.

When multiple calls are fired, the first person to answer gets connected and the rest of the calls are dropped. To make sure that the call is answered by a person and not by voice mail, use the confirmKey and confirmSound attributes.

The example XML here requires the call recipient to input the digit 5 after answering the call to connect.

Vobiz requests the confirmSound URL using the POST HTTP method for a valid Play, Speak, or a Wait XML element. To play a message asking the recipient to input a DTMF tone to connect the call, return the second XML example.

## Example

### Response

```xml theme={null}
<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Dial confirmSound="https://your-domain.com/confirm_sound/" confirmKey="5">
        <Number>12025551111</Number>
        <Number>12025552222</Number>
        <Number>12025553333</Number>
    </Dial>
</Response>
```

Return the following XML to play a message.

```xml theme={null}
<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Speak>Enter the digit 5 to connect the call</Speak>
</Response>
```
