Avaya Jtapi Programmer 39-s Guide

The is an essential technical resource for developers building telephony applications within the Avaya ecosystem. It serves as the primary manual for implementing the Java Telephony API (JTAPI) to control and monitor telephony resources on Avaya Communication Manager via the AES server. Key Content Overview

Best for call-centric event tracking (e.g., call rings, call clears, call connects).

To transfer or conference a call using standard methods, you must use the CallControlCall sub-interface to manipulate two distinct Call objects (the original active call and the consultation call).

Join a recording server as a silent observer to an active call.

The Avaya JTAPI implementation is built on the industry-standard Java Telephony API (JTAPI) but is specifically tailored for Avaya's infrastructure: avaya jtapi programmer 39-s guide

Known extensions, VDNs (Vector Directory Numbers), or ACD split/skills to monitor. Classpath Configuration

| Concept | Plain English | |--------|----------------| | | Your app makes phone A call phone B | | Call Detail Recording | No – that’s CDR. JTAPI does live events. | | Device/Feature ID | Avaya’s internal feature codes (e.g., hold = Feature 4) | | Auto-login | Yes – provider can persist sessions across CM failovers | | CSTA mapping | JTAPI events map to ECMA-269, but Avaya extends it |

Understanding the architectural pipeline is crucial for troubleshooting and designing scalable JTAPI applications. The is an essential technical resource for developers

What are you trying to implement (e.g., transfer, supervisor barge-in, predictive dialing)? Which version of Avaya Aura / AES are you targeting?

Enterprise CTI monitors real-time changes to lines to generate call statistics or pop screen interfaces for CRM apps. This is done by adding event listeners to providers, addresses, and terminals. Monitoring a Target Extension

Avaya JTAPI callbacks run directly within the execution context of the internal SDK notify threads.

To receive call information, you must register a CallObserver or TerminalObserver on a specific address or terminal. To transfer or conference a call using standard

import javax.telephony.*; import javax.telephony.events.*; public class CallMonitor implements AddressObserver @Override public void addressChangedEvent(AddrEv[] events) for (AddrEv event : events) switch (event.getID()) case CallCentConnRingEv.ID: System.out.println("Inbound call is ringing on extension!"); break; case ConnEstEv.ID: System.out.println("Call answered / Connection established."); break; case ConnDisconnectedEv.ID: System.out.println("Call disconnected / Hung up."); break; Use code with caution. Registering the Observer

Avaya's JTAPI implementation extends the standard Java Telephony API specification defined by Sun Microsystems. It acts as a client-side wrapper that communicates with Avaya Application Enablement Services (AES). The Communication Pipeline Executes JTAPI code methods.

Java developers integrating Avaya phone systems with CRM software, building custom softphones, or creating call center reporting tools.

Standard JTAPI (from Oracle) defines generic call control. Avaya extends these interfaces to support specific PBX features. The Programmer's Guide dedicates chapters to
