# Azure Communication CallingServer (Java) - DEPRECATED

```

## Class Name Changes

| `CallingServerClient` | `CallAutomationClient` |
| `CallingServerClientBuilder` | `CallAutomationClientBuilder` |
| `CallConnection` | `CallConnection` (same) |

## Legacy Client Creation

```java
// OLD WAY (deprecated)
import com.azure.communication.callingserver.CallingServerClient;
import com.azure.communication.callingserver.CallingServerClientBuilder;

CallingServerClient client = new CallingServerClientBuilder()
    .connectionString("")
    .buildClient();

// NEW WAY
import com.azure.communication.callautomation.CallAutomationClient;
import com.azure.communication.callautomation.CallAutomationClientBuilder;

CallAutomationClient client = new CallAutomationClientBuilder()
    .connectionString("")
    .buildClient();
```

## Legacy Recording

```java
// OLD WAY
StartRecordingOptions options = new StartRecordingOptions(serverCallId)
    .setRecordingStateCallbackUri(callbackUri);

StartCallRecordingResult result = client.startRecording(options);
String recordingId = result.getRecordingId();

client.pauseRecording(recordingId);
client.resumeRecording(recordingId);
client.stopRecording(recordingId);

// NEW WAY - see azure-communication-callautomation skill
