Introduction

The Cisco Unified Java Telephony Application Programming Interface (JTAPI) acts as a portable, object-oriented API for computer telephony integrated call control. The package of JTAPI interfaces, located in the javax.telephony.* hierarchy, defines a programming model by which Java applications can interact with telephony resources such as PBXs and telephones. The Cisco Unified JTAPI implementation supports Java application access to the Cisco architecture for voice, video and data communication systems according to the JTAPI v 1.2 specification. Furthermore, Cisco Unified JTAPI exposes Cisco-specific events and methods for certain telephony resources such as calls and connections.

Purpose

Providing an unchanging programming interface under which varied implementations may stand represents one of the primary goals of a standard Application Programming Interface (API) such as JTAPI. In implementing JTAPI for the Cisco Unified Communications Manager platform, Cisco tries to conform as closely as possible to the JTAPI specification while providing extensions that enhance JTAPI and expose the advanced features of Cisco Unified Communications Manager to applications.

As new versions of Cisco Unified Communications Manager and the Cisco Unified JTAPI implementation are released, variances in the API should be very minor and should tend in the direction of compliance. Cisco remains committed to maintaining its API extensions with the same stability and reliability, though additional extensions may be provided as new Cisco Unified Communications Manager features become available.

This document outlines some basic JTAPI concepts including transfer and conference extensions. It also describes the support of extensions to the Sun JTAPI v 1.2 specification.

Organization

The following table provides an outline of this document's organization.

Chapter
Description

Chapter 1, "Overview"

This chapter introduces the major concepts with which you need to be familiar before creating JTAPI applications for Cisco IP Telephony Solutions.

Chapter 2, "Backward Compatibility"

This chapter describes the features that assist you in writing applications that will remain backwards compatible with future Cisco JTAPI updates.

Chapter 3, "Cisco Unified JTAPI Installation"

This chapter describes the installation procedures.

Chapter 4, "Cisco Unified JTAPI Implementation"

This chapter describes the JTAPI interfaces and classes that are available in the implementation.

Chapter 5, "Cisco Unified JTAPI Examples"

This chapter provides the source code for makecall, which is the Cisco Unified JTAPI program that is used to test the JTAPI installation.

Appendix A, "Message Sequence Charts"

This appendix contains message flow diagrams.

Appendix B, "Cisco Unified JTAPI Classes and Interfaces"

This appendix contains a listing of all the classes and interfaces that are available in Cisco Unified JTAPI.

Appendix C, "Troubleshooting Cisco Unified JTAPI"

This appendix contains CTI Error Codes, CiscoEvent IDs, and other troubleshooting information.


Audience

This document applies for telephony software developers who are developing Cisco Unified Communications applications that require JTAPI. This document assumes that the programmer is familiar with both the Java language and the Sun JTAPI v 1.2 specification.

New and Changed Information

New features or changes for Cisco Unified JTAPI are described in the Release Notes for the specified release of Cisco Unified Communications Manager.
