# SignalWire.Relay.Calling.CallDetect

This object represents a call detection.

## Constructor

The only constructor is the default constructor, properties should all be assigned by initializer or after construction.

**Parameters**

None

**Examples**

> Basic Example

```csharp
CallDetect detect = new CallDetect
{
    Type = CallDetect.DetectType.machine,
    Parameters = new CallDetect.MachineParams
    {
        // Use default machine detection parameters
    }
};
```

## Properties

| Property     | Type                                                                        | Description                                                 |
| ------------ | --------------------------------------------------------------------------- | ----------------------------------------------------------- |
| `Type`       | [`SignalWire.Relay.Calling.CallDetect.DetectType`][call-detect-detect-type] | This object indicates the type of the configuration object. |
| `Parameters` | object                                                                      | The configuration object for the operation.                 |

## Methods

## ParametersAs\<T>()

This is a helper method to convert the `Parameters` to the real type.

**Parameters**

| Parameter | Type | Required                                   | Description                                                                                                                                     |
| --------- | ---- | ------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------- |
| `T`       | Type | <span class="required-arg">required</span> | This is the data type for the conversion, see [`SignalWire.Relay.Calling.CallDetect.DetectType`][call-detect-detect-type] for more information. |

**Returns**

`T` - This is an instance of the data type resulting from the conversion, see [`SignalWire.Relay.Calling.CallDetect.DetectType`][call-detect-detect-type] for more information.

**Examples**

```csharp
CallDetect.DigitParams digitParams = detect.ParametersAs<CallDetect.DigitParams>();
CallDetect.FaxParams faxParams = detect.ParametersAs<CallDetect.FaxParams>();
CallDetect.MachineParams machineParams = detect.ParametersAs<CallDetect.MachineParams>();
```

## Events

None
