# Voice Machine Detection [#](https://gudhub.com/docs/automation-nodes/voice-machine-detection/#voice-machine-detection)

**Voice Machine Detection** is a node that allows you to check the certain phone numbers. Specifically, it determines who answers the call. This is useful for checking some contacts.

## Inputs [#](https://gudhub.com/docs/automation-nodes/voice-machine-detection/#inputs)

The current node has only default input sockets.

### Default Input Sockets [#](https://gudhub.com/docs/automation-nodes/voice-machine-detection/#default-input-sockets)

There are two default input sockets. Both receive data that is important for making a call. The recipient's phone number will be checked.

| Name | Data Type | Description |
| :-- | :-- | :-- |
| From | `value` | _accept the phone number from which the call will be made_ |
| To | `value` | _accepts the phone number to be checked_ |

### Additional Input Sockets [#](https://gudhub.com/docs/automation-nodes/voice-machine-detection/#additional-input-sockets)

The current node has no additional input sockets.

## Outputs [#](https://gudhub.com/docs/automation-nodes/voice-machine-detection/#outputs)

The voice detector has only one output socket.

### Default Output Sockets [#](https://gudhub.com/docs/automation-nodes/voice-machine-detection/#default-output-sockets)

The single output socket returns the result of the recipient checking. Namely, it shows who answers the call: machine\_start, person, fax, or unknown in cases where the detector cannot determine who called.

| Name | Data Type | Description |
| :-- | :-- | :-- |
| Result | `value` | _returns the result of the check_ |

### Additional Output Sockets [#](https://gudhub.com/docs/automation-nodes/voice-machine-detection/#additional-output-sockets)

There are no settings for adding additional output sockets.

## Options [#](https://gudhub.com/docs/automation-nodes/voice-machine-detection/#options)

![Default settings of voice machine detection node](https://bitbucket.org/AAtlas/gudhub-documentation/raw/master/Automation_Nodes/automation-nodes/voice-machine-detection-default-settings.jpg "Default settings")

| Name | Description |
| :-- | :-- |
| Account SID | allows you to enter your Twilio account SID; [details...](#account-sid) |
| Auth Token | allows you to enter a Twilio authentication token; [details...](#auth-token) |
| Notes | allows to leave any notes in settings; [details...](#notes) |

### Account SID [#](https://gudhub.com/docs/automation-nodes/voice-machine-detection/#account-sid)

To use the current node, you must have a Twilio account, where you can get the credentials for this and the following settings. In the first **Voice machine detection** setting, you must enter the [account SID](https://www.twilio.com/docs/glossary/what-is-a-sid) that will allow the node to access your Twilio account.

### Auth Token [#](https://gudhub.com/docs/automation-nodes/voice-machine-detection/#auth-token)

This is the second option where you need to enter the [Auth Token](https://www.twilio.com/docs/iam/api/authtoken) from your Twilio account, which is used to authenticate the API request.

### Notes [#](https://gudhub.com/docs/automation-nodes/voice-machine-detection/#notes)

The last option is used by default. This is the field where you can enter any necessary notes.
