# 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

```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>
    <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

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

CallingServerClient legacyClient = new CallingServerClientBuilder()
    .connectionString("<connection-string>")
    .buildClient();

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

CallAutomationClient automationClient = new CallAutomationClientBuilder()
    .connectionString("<connection-string>")
    .buildClient();
```

## Legacy Recording

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

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

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

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

## For New Development

**Do not use this SDK for new projects.** 

See the `azure-communication-callautomation-java` skill for:
- Making outbound calls
- Answering incoming calls
- Call recording
- DTMF recognition
- Text-to-speech / speech-to-text
- Adding/removing participants
- Call transfer

## Trigger Phrases

- "callingserver legacy", "deprecated calling SDK"
- "migrate callingserver to callautomation"

## When to Use
Use only when maintaining historical CallingServer code or planning migration to azure-communication-callautomation-java; do not start new integrations with the retired package.

## Limitations
- Legacy and new snippets are alternative fragments, not a drop-in migration. Pin reviewed package versions and verify the exact replacement API; the legacy recording options are not assumed compatible with Call Automation.
- Call control and recording can affect real participants, costs and sensitive communications. Obtain call/account authorization and required participant consent, keep credentials out of code/logs, and never place or record a call merely to validate these examples.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
