  1. Internet and Telephony Kwan Hong Lee Jonathan Lin

  2. Introduction • Goal • Integrate telephone network and the Internet • Motivation • Great potential in applications that make use of this integration

  3. JTAPI Architecture

  4. How does it work? • PBX Switch • Telephony Server • JTAPI

  5. PBX Switch • Lucent Generic 3 Switch • Provides telephony services • call management, billing, call conferencing etc. • Very complicated stuff • Currently three analog phones connected

  6. 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

  7. 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

  8. 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

  9. 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

  10. ASAI • Communications interface that allows applications to access switch features and control switch calls • Implemented using Ethernet interface
