From the author

Azure Communication Services CallingServer (legacy) Java SDK. Note - This SDK is deprecated. Use azure-communication-callautomation instead for new projects. Only use this skill when maintaining legacy code.
— the description by Microsoft

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides reference information for the deprecated Azure Communication Services CallingServer Java SDK. It is intended strictly for developers maintaining legacy applications that have not yet migrated to the current Call Automation SDK. The documentation outlines the necessary steps to transition from the old CallingServer client classes and recording methods to the modern Call Automation equivalents.

What it does

  • Provides legacy documentation for the CallingServer Java SDK
  • Outlines class name changes from CallingServer to Call Automation
  • Demonstrates legacy client initialization patterns
  • Shows legacy call recording implementation
  • Facilitates migration planning to modern SDKs

When to use it

  • When maintaining or debugging existing codebases using the deprecated CallingServer SDK
  • When planning a migration from CallingServer to Call Automation
  • When identifying legacy dependencies that need to be updated

Advantages

  • Clearly identifies deprecated components
  • Provides direct mapping between legacy and modern API structures
  • Reduces technical debt by highlighting the path to migration

Usage examples

“How do I initialize the legacy CallingServer client in Java?”
The agent provides the code snippet using CallingServerClientBuilder to establish a connection string-based client.
“What is the replacement for CallingServerClient in the new SDK?”
The agent identifies CallAutomationClient as the direct replacement and provides the updated import and initialization syntax.

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>

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

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"
