# Fraud Detection \[YouMail]

## Introduction

This configuration note describes how to set up Telcobridges ProSBC for adding YouMail fraud protection service to any system.

### Prerequisites

* ProSBC devices must be installed with release 3.1.113 or later. Here is a link to the installation guides.
* Need to have an account at [YouMail](https://www.youmail.com/) to get a Security ID (SID) and an API key. Trial accounts are available.
* ProSBC must be configured in one of the [ProSBC Use Cases](/use-cases/interoperability-examples.md). This script will be an addon to the rest of the configuration.

<br>

### Example Environment for Fraud Protection with YouMail

Calls received on ProSBC will systematically send a HTTPS request to the YouMail service running on the cloud.\
The calling number (ANI) will be verified by the YouMail service and will return a response to the ProSBC with a level.\
Call Routes can be configured to pass valid numbers (level 0), pass or block potential spam numbers (level 1), and block fraudulous calls (level 2)

The configuration is mainly adding a script to the ProSBC. See [Adding the YouMail Script](/configuration-details/configuration-by-use-case/configuration-for-adding-youmail-script-to-routing-scripts.md)

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://prosbcdocs.telcobridges.com/use-cases/interoperability-examples/fraud-detection-youmail.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
