Migration to Call Automation

```xml

<!-- OLD (deprecated) -->

<dependency>

<groupId>com.azure</groupId>

<artifactId>azure-communication-callingserver</artifactId>

<version>1.0.0-beta.5</version>

</dependency>

<!-- NEW (use this instead) -->

<dependency>

<groupId>com.azure</groupId>

<artifactId>azure-communication-callautomation</artifactId>

```

Class Name Changes

| CallingServer (Old) | Call Automation (New) |

|---------------------|----------------------|

| `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("<connection-string>")

.buildClient();

// NEW WAY

import com.azure.communication.callautomation.CallAutomationClient;

import com.azure.communication.callautomation.CallAutomationClientBuilder;

CallAutomationClient client = new CallAutomationClientBuilder()

.connectionString("<connection-string>")

.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

```
