What is azure-communication-callautomation-java?

A Java SDK for automating phone-call workflows on the server. It can answer, reject, redirect, record, and control calls, including interactive voice-response menus and AI-assisted interactions.

Use it to build IVR menus, route callers, record calls, manage established calls, and add AI interactions.

It replaces manual handling of call-control details when an application needs to manage phone calls programmatically.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00028	$0.01853
Opus 5	$0.00014	$0.00927
Sonnet 5	$0.00006	$0.00371
Haiku 4.5	$0.00003	$0.00185

Security

Grade A, and why

azure-communication-callautomation-java scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

Azure Communication Call Automation (Java)

Build server-side call automation workflows including IVR systems, call routing, recording, and AI-powered interactions.

Installation

<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-communication-callautomation</artifactId>
    <version>1.6.0</version>
</dependency>

Client Creation

import com.azure.communication.callautomation.CallAutomationClient;
import com.azure.communication.callautomation.CallAutomationClientBuilder;
import com.azure.identity.DefaultAzureCredentialBuilder;

// With DefaultAzureCredential
CallAutomationClient client = new CallAutomationClientBuilder()
    .endpoint("https://<resource>.communication.azure.com")
    .credential(new DefaultAzureCredentialBuilder().build())
    .buildClient();

// With connection string
CallAutomationClient client = new CallAutomationClientBuilder()
    .connectionString("<connection-string>")
    .buildClient();

Key Concepts

Class	Purpose
`CallAutomationClient`	Make calls, answer/reject incoming calls, redirect calls
`CallConnection`	Actions in established calls (add participants, terminate)
`CallMedia`	Media operations (play audio, recognize DTMF/speech)
`CallRecording`	Start/stop/pause recording
`CallAutomationEventParser`	Parse webhook events from ACS

Create Outbound Call

import com.azure.communication.callautomation.models.*;
import com.azure.communication.common.CommunicationUserIdentifier;
import com.azure.communication.common.PhoneNumberIdentifier;

// Call to PSTN number
PhoneNumberIdentifier target = new PhoneNumberIdentifier("+14255551234");
PhoneNumberIdentifier caller = new PhoneNumberIdentifier("+14255550100");

CreateCallOptions options = new CreateCallOptions(
    new CommunicationUserIdentifier("<user-id>"),  // Source
    List.of(target))                                // Targets
    .setSourceCallerId(caller)
    .setCallbackUrl("https://your-app.com/api/callbacks");

CreateCallResult result = client.createCall(options);
String callConnectionId = result.getCallConnectionProperties().getCallConnectionId();
