# Sequential dialing

> Dial multiple Vobiz numbers sequentially with the Dial element - set per-Number timeouts so the next destination is tried only after the previous fails.

This example calls out to two phone numbers sequentially. The first call is made to a number with a timeout value of 20 seconds. If the call is not answered within that time, Vobiz will dial out to the second number.

## Example

### Response

```xml theme={null}
<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Dial action="https://your-domain.com/dial_action/" hangupOnStar="true" dialMusic="https://your-domain.com/music.mp3">
        <Number timeout="20">12025551111</Number>
        <Number timeout="20">12025552222</Number>
    </Dial>
</Response>
```

**Tip:** To control the number shown to each destination, add the `callerId` attribute to the `Dial` element - for example `<Dial callerId="+14155551234">`. If omitted, the current caller's caller ID is used. See [Transfer a Call](/call/transfer-call) for more on the `Dial` element.
