Introduction

Goal Integrate telephone network and the

Internet

Motivation Great potential in applications that

make use of this integration

JTAPI Architecture

How does it work?

PBX SwitchTelephony ServerJTAPI

PBX Switch

Lucent Generic 3 SwitchProvides telephony services

call management, billing, call conferencing etc.

Very complicated stuffCurrently three analog phones

connected

Telephony Server

Telephony Services Module Provides communication between

applications and switch driver Routes messages and events

Switch driver Terminates CTI link and protocol map CTI protocol to TSAPI

Java Telephony API

Telephony application development made easier object oriented, reusable, cross platform

Integrates telephony services with web applications Telephony services can be controlled

through the Internet applets

JTAPI Core & Extensions

java.telephony java.telephony.callcontrol

placing calls on hold, transferring telephone calls, and conferencing telephone calls

This package also provides a more detailed state model of telephone calls

java.telephony.callcenter Routing, Automated Call Distribution

(ACD), Predictive Calling, and associating

application data with telephony objects

java.telephony.media java.telephony.privatedata

TSAPI

Vehicle that JTAPI uses to communicate with Telephony Services drivers

API that allows applications to control the PBX switch to provide telephony services, call

control services, call/device monitoring services, and query services

ASAI

Communications interface that allows applications to access switch features and control switch calls

Implemented using Ethernet interface
