The Avaya JTAPI Programmer’s Guide is a critical technical resource for developers building telephony applications on the Avaya Aura® Application Enablement Services (AES) platform. It provides the necessary framework to leverage Java Telephony API (JTAPI) for third-party call control, allowing applications to interact directly with Avaya Aura Communication Manager. Core Architecture and Purpose

The Avaya JTAPI implementation acts as a client-side interface to the TSAPI Service. While JTAPI is an industry-standard object-oriented model for telephony, Avaya’s version includes value-added extensions to support specific Communication Manager features like private data services.

Third-Party Call Control: Enables applications to monitor and control calls on behalf of multiple users, rather than just the local user.

Call Model: Based on standard JTAPI call objects, such as Call, Address, and Terminal, to ensure cross-platform portability.

Integration: Uses the TSAPI Service to communicate with Communication Manager via a secure Tlink (Transport Link). Key Content for Developers

The guide is structured to lead a developer from environment setup through to complex call handling. Essential sections include: JTAPI programmers - Avaya Documentation

Recommendations

Based on the Avaya JTAPI Programmer's Guide, we recommend the following:

  1. Developers should have a strong understanding of Java programming: JTAPI is a Java-based API, and developers should have a strong understanding of Java programming concepts.
  2. Developers should familiarize themselves with Avaya communication systems: Developers should have a basic understanding of Avaya communication systems and their features.
  3. Developers should use the JTAPI Programmer's Guide as a reference: The guide provides a range of programming examples and tutorials that can help developers get started with JTAPI.

The Avaya JTAPI Programmer's Guide is the primary resource for developers building Java-based Computer Telephony Integration (CTI) applications for Avaya communication systems. It provides the technical foundation for interacting with Avaya Aura® Application Enablement Services (AES) to control telephony features like call routing, monitoring, and automated dialing. Core Architecture and Concepts

The Avaya JTAPI implementation is built on the industry-standard Java Telephony API (JTAPI) but is specifically tailored for Avaya's infrastructure:

TSAPI Foundation: Avaya JTAPI essentially acts as a Java wrapper for the TSAPI Service . Application requests on JTAPI objects are converted into Computer Supported Telecommunications Applications (CSTA) messages, which the TSAPI service then translates for the Communication Manager (CM).

Provider Object: This is the central abstraction representing the telephony service provider (the Communication Manager ). Developers interact with this object to obtain references to all other JTAPI objects. The JTAPI Model: A standard call model includes: Call: Represents the actual telephone call.

Connection: Represents the relationship between a Call and an Address. Address: Usually represents a phone number or extension.

Terminal: Represents the physical hardware (e.g., a desk phone). Essential Programming Tasks

The programmer's guide details how to execute standard telephony operations:

Originating a Call: Creating a new Call object and using the connect() method to link it to the originating and destination addresses.

Detecting Incoming Calls: Implementing CallObserver or TerminalObserver to listen for events like CallActive or ConnectionAlerting.

Answering and Disconnecting: Using methods on the TerminalConnection or Connection objects to manipulate the state of an active call.

Conferencing and Transferring: Leveraging Avaya-specific extensions to handle complex multi-party call scenarios. Avaya Extensions and Deviations

While based on standard JTAPI, Avaya provides "value-added" extensions to support unique Communication Manager features:

Private Data Services: Allows developers to access extended Communication Manager features not covered by the core JTAPI specification.

Deviations: Note that some standard JTAPI APIs may have extra preconditions or be unsupported due to the underlying TSAPI architecture. Setting Up Your Environment

The "Avaya JTAPI Programmer's Guide" is a comprehensive guide for developers who want to create applications using the Avaya JTAPI (Java Telephony API) software. Here's a condensed guide to get you started:

What is Avaya JTAPI?

Avaya JTAPI is a Java-based API that allows developers to create telephony applications that integrate with Avaya communication servers. JTAPI provides a set of programming interfaces that enable developers to access and control telephony features, such as call handling, conferencing, and voicemail.

Key Concepts

  1. JTAPI: Java Telephony API, a set of Java interfaces for building telephony applications.
  2. Avaya Communication Server: The Avaya server that provides telephony services and integrates with JTAPI applications.
  3. JTAPI Provider: A software component that manages the interaction between the JTAPI application and the Avaya Communication Server.

Getting Started

  1. Prerequisites: Familiarize yourself with Java programming, telephony concepts, and Avaya communication servers.
  2. JTAPI Software: Obtain the Avaya JTAPI software and install it on your development machine.
  3. Avaya Communication Server: Ensure you have access to an Avaya Communication Server, either locally or remotely.

JTAPI Programming Basics

  1. JTAPI Core Components:
    • Provider: Manages the interaction between the JTAPI application and the Avaya Communication Server.
    • Connection: Represents a connection to the Avaya Communication Server.
    • Call: Represents a telephony call.
  2. JTAPI Events:
    • CallEvents: Notify the application of call-related events, such as call establishment, call termination, or call hold.
    • ProviderEvents: Notify the application of provider-related events, such as connection establishment or termination.

Example JTAPI Application

Here's a simple JTAPI application example in Java:

import java.util.*;
import javax.telephony.*;
import javax.telephony.events.*;
public class JTAPIExample 
  public static void main(String[] args) 
    // Create a JTAPI provider
    Provider provider = new Provider();
// Connect to the Avaya Communication Server
    Connection connection = provider.connect(" server IP address", 5060);
// Create a call
    Call call = connection.createCall();
// Add a call listener
    call.addCallListener(new CallListener() 
      public void callEstablished(CallEvent event) 
        System.out.println("Call established");
public void callTerminated(CallEvent event) 
        System.out.println("Call terminated");
);
// Make a call
    call.makeCall("destination phone number");

This example demonstrates a basic JTAPI application that connects to an Avaya Communication Server, creates a call, and listens for call events.

Tips and Best Practices

This guide provides a brief introduction to the Avaya JTAPI Programmer's Guide. For a more comprehensive understanding, I recommend consulting the official documentation and API references. Happy coding!

The Avaya JTAPI (Java Telephony API) Programmer's Guide is the primary resource for developing, debugging, and deploying telephony applications on the Avaya Aura® Application Enablement Services (AES) platform. This implementation allows developers to control telephony objects, such as calls and connections, through a sophisticated Java library that translates high-level API calls into CSTA messages for communication with Avaya Communication Manager (CM). 1. Environment Setup & Configuration

Before coding, you must configure both the AES server and the development environment: AES Server Configuration:

Create CTI User: Log in to the AES Web GUI, add a user with the TSAPI User role, and assign them to the cti_provisioned_apps group.

Add Switch Connection: In the AES interface, add your CM switch name and enable JTAPI services. This blog post provides a developer-focused overview of

CTI Link: On the Avaya CM SAT, run add cti-link (Type: ADJ-IP) to establish the link.

Developer SDK: Obtain and install the TSAPI/JTAPI SDK (available via Avaya DevConnect).

Dependencies: Ensure your classpath includes essential Avaya JTAPI JAR files (e.g., ecsjtapi.jar). 2. Core Programming Workflow

Programming with Avaya JTAPI involves a specific sequence of object factory calls to establish a connection to the switch. JTAPI programmers - Avaya Documentation
