# dtmf
The `dtmf` verb generates a string of dtmf digit signals. These are sent as RTP payloads using [RFC 3822](https://datatracker.ietf.org/doc/html/rfc2833).
```json
{
"verb": "dtmf",
"dtmf": "0276",
"duration": 250
}
```
You can use the following options in the `dtmf` action:
| option | description | required |
| ------------- |-------------| -----|
| dtmf | a string containing a sequence of dtmf digits (0-9,*,#) | yes |
| duration | the length of each digit, in milliseconds, Defaults to 500 | no |
