### playTonesTo Object

The[ tone board](/cad/tutorials/customization/tone-board.md) allows you to play tones to specific identifiers, dispatch calls, departments, and more. The `playTonesTo` array specifies who or what the tone was sent to.

#### type Enum

The `type` field is an enumerator value as follows:

| Enum (Integer) | Description                |
| -------------- | -------------------------- |
| 0              | All Active Units           |
| 1              | Specified Dispatch Call ID |
| 2              | Specified Agency           |
| 3              | Specified Department       |
| 4              | Specified Subdivision      |
| 5              | Specified Unit Identifier  |
| 6              | Specified Unit Group       |

#### value Property

The `value` property represents the specific target for the `type`.\
Ex: On a `type` `1` (dispatch call) the `value` would be a number representing the dispatch call ID.
