Restrict media zones

When a user joins a channel, Voice SDK automatically connects them to the Agora SDRTN® media zone that is geographically closest to the user. However, to meet the laws and regulations of the user's country, you may need to specify, or filter out connections to a specific geographical zone. Agora enables you to control and customize data routing in your app by specifying the Agora SDRTN® media zone users connect to.

Understand the tech

After you turn on the restricted media zones feature, the SDK only accesses the Agora server in the specified zone(s), irrespective of the geographical location of the user. As an example, the following table shows the outcome if you specify North America as the access zone, and users connect to Agora SDRTN® from North America and China respectively:

The following figure shows the workflow you implement to restrict access to media zones:

Prerequisites

Ensure that you have implemented the SDK quickstart in your project.

Implement restricted media zones

This section shows you how to restrict access to media zones in your app.

You specify the access zones by setting the RtcEngineConfig.mAreaCode parameter when calling the create method to create an RtcEngine instance. The available zones are:

• AREA_CODE_GLOB: Global (Default)
• AREA_CODE_CN : Mainland China
• AREA_CODE_NA : North America
• AREA_CODE_EU : Europe
• AREA_CODE_AS : Asia excluding Mainland China
• AREA_CODE_JP : Japan
• AREA_CODE_IN : India

Include a media zone

To limit access to servers in only one zone, such as North America, set config.mAreaCode = AREA_CODE_NA; before creating the RtcEngine instance:

// Initialize the App and join the channel
private void initializeAndJoinChannel() {
  try {
    RtcEngineConfig config = new RtcEngineConfig();
    config.mAppId = appId;
    config.mContext = mContext;
    config.mEventHandler = mEngineEventHandler.mRtcEventHandler;
    // Restrict access to servers in North America only
    config.mAreaCode = AREA_CODE_NA;
    mRtcEngine = RtcEngine.create(config);
  } catch (Exception e) {
      throw new RuntimeException("Check the error.");
  }
}

// Initialize the App and join the channel
private fun initializeAndJoinChannel() {
  try {
    val config = RtcEngineConfig()
    config.mAppId = appId
    config.mContext = mContext
    config.mEventHandler = mEngineEventHandler.mRtcEventHandler

    mRtcEngine = RtcEngine.create(config)
  } catch (e: Exception) {
      throw RuntimeException("Check the error.")
  }
}

Exclude a media zone

To exclude servers in a zone, such as Mainland China, set config.mAreaCode = AREA_CODE_GLOB ^ AREA_CODE_CN; before creating the RtcEngine instance:

// Initialize the App and join the channel
private void initializeAndJoinChannel() {
  try {
    RtcEngineConfig config = new RtcEngineConfig();
    config.mAppId = appId;
    config.mContext = mContext;

    mRtcEngine = RtcEngine.create(config);
  } catch (Exception e) {
