Client configuration enables you to customize the behavior of your Signaling client instance according to your app's requirements.

    ## Understand the tech [#understand-the-tech-3]

    When initializing a Signaling client instance, configure any or all of the following features:

    * **Geographical area access**
      When a user joins a channel, Signaling SDK automatically connects them to the closest geographical region of Agora SDRTN®. However, to comply with local laws and regulations, you may want to specify or restrict connections to a specific geographical area. Agora enables you to control and customize data routing in your app by specifying the Agora SDRTN® region users connect to.

    * **Private deployment**
      Private deployment enables you to deploy and manage the Signaling environment on your own infrastructure rather than using Agora services. This feature is fully supported since version 2.2.0.

    * **Logging**
      Logging enables you to output detailed information from the SDK for locating and fixing problems during the development and testing phases. By configuring logging settings, you can control the amount and type of information logged by the SDK.

    * **Data encryption**
      Enabling encryption ensures that only authorized users are able to read messages sent through Signaling. Signaling provides built-in encryption methods that guarantee data confidentiality during transmission. For implementation details, see [Data encryption](../secure-your-app-and-data/data-encryption).

    ## Prerequisites [#prerequisites-3]

    Ensure that you have integrated the Signaling SDK in your project and implemented the framework functionality from the [SDK quickstart](../../index) page.
