Azure Communication CallingServer (Java) - DEPRECATED

⚠️ DEPRECATED: This SDK has been renamed to Call Automation. For new projects, use azure-communication-callautomation instead. This skill is for maintaining legacy code only.

Migration to Call Automation

<!-- 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>
    <version>1.6.0</version>
</dependency>

Class Name Changes

| CallingServer (Old) | Call Automation (New) | |---------------------|----------------------| | CallingServerClient | CallAutomationClient | | CallingServerClientBuilder | CallAutomationClientBuilder | | CallConnection | CallConnection (same) | | ServerCall | Removed - use CallConnection |

Legacy Client Creation

// 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

// 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
