Core Call Control Concepts
: Focuses on the "how-to" aspect, covering architecture, setup of the development environment, and practical application writing.
For developers working with Avaya Communication Manager (CM) and Avaya Aura® platforms, the is not merely a document—it is the authoritative blueprint for building robust, scalable, and real-time telephony applications. Whether you are monitoring agent states, controlling call flows, or logging detailed call details, mastering this guide is non-negotiable.
Once your environment is set up, it's time to write some code.
Represents the physical endpoint hardware (the desk phone or softphone). Call: Represents the dynamic instance of a telephone call. avaya jtapi programmer 39-s guide
Your application server requires bidirectional TCP/IP communication with the Avaya AES instance. Ensure your network administrators open the standard secure AES JTAPI ports: : Port 5628 Encrypted (TLS) TSAPI/JTAPI Service Link : Port 5629 3. Provider Initialization and Authentication
You need the IP address, a valid user ID, and a password configured on the AES server.
To monitor extensions, your application must implement specific Observers. To receive events for an extension, you would add a CallControlAddressObserver to an Address object. If the observer is not set up correctly, you may get errors like "No observer on extension: XXXX". To monitor an agent for all calls they handle, you would add a CallControlTerminalObserver to the Terminal representing the agent's device.
The JTAPI architecture consists of the following components: import javax
: On the Avaya CM SAT, run add cti-link (Type: ADJ-IP) to establish the link.
: Telephony event loops must remain unblocked. Never execute long-running operations, such as intensive database queries or third-party API calls, directly inside a JTAPI event listener thread. Always hand off incoming events to an internal worker thread pool ( ExecutorService ).
Avaya's JTAPI implementation has several important deviations from the standard specification you should be aware of:
Do not attempt to “learn by Googling.” Avaya’s ecosystem is vast and unique. Download the official guide, work through the examples, set up a lab environment (even a virtual Avaya CM Express), and experiment. Your future self—and your enterprise users—will thank you. For developers working with Avaya Communication Manager (CM)
: Enables applications to monitor and control calls on behalf of multiple users, rather than just the local user.
When your application uses JTAPI to place a call, the flow of control is as follows:
If you are developing in an integrated development environment (IDE) like IntelliJ IDEA or Eclipse, ensure that the directory containing your tsapi.pro file is added to your project's classpath so that the JTAPI library can find it.
