JTAPI supports both first- and third-party telephony application domains. The API is designed to make programming simple applications easy, while providing those features necessary for advanced telephony applications. The "core" API provides the basic call model and rudimentary telephony features, such as placing telephone calls and answering telephone telephone class java. The core API is surrounded by standard extension APIs providing functionality telephone class java specific telephony domains, such as call centers and media stream access.

Applications written using the Java Telephony API are portable across the various computer platforms and telephone systems, telephone class java.

Additionally, independent hardware vendors may choose telephone class java provide implementations of telephone class java Java Telephony API on top of their own proprietary hardware, telephone class java. Major contributors to the ECTF experts group for release 1. Version 1. JTAPI runs on a variety of system configurations, including centralized servers with direct access to telephony resources, telephone class java, and remote network computers with access to telephony resources over a network, telephone class java.

In the first configuration, telephone class java, a network computer is running the JTAPI application and is accessing telephony resources over a network, as illustrated in Figure 1.

In the second configuration, the application is running on a computer with its own telephony resources, as illustrated in Figure 2. This workstation can be a network computer with only a display, keyboard, processor, and some memory. It accesses network resources, making use of a centralized server that manages telephony resources.

The following telephone class java shows this configuration. In a desktop configuration, telephone class java, the JTAPI application or Java applet runs on the same workstation that houses the telephony resources. The following diagram shows the desktop configuration. Each package provides a specific piece of functionality for a certain aspect of computer-telephony applications. Implementations of telephony servers choose the packages they support, depending upon the capabilities of their underlying platform and hardware.

Applications may query for the packages supported by the implementation they are currently using. Additionally, application developers may concern themselves with only the supported packages applications need to telephone class java a task. The core package provides the basic framework to model telephone calls and rudimentary telephony features. These features include placing a telephone call, telephone class java, answering a telephone call, and disconnecting a connection to a telephone call.

Simple telephony applications will only need telephone class java use the core to accomplish their tasks, and do not need to concern themselves with the details of other packages.

For example, the core package permits applet designers to add telephone capabilities to a Web page with ease. These extension packages each bring additional telephony functionality to the API. Currently, the following extension packages exist for this API: call control, call center, media, phone, private data, and capabilities packages, telephone class java. Each package is summarized below in terms of the features it brings to JTAPI, telephone class java, and is linked to a separate overview document and specifications.

In other words, telephony server implementations choose which extension packages in addition to the core package they implement, based upon the capabilities of the underlying hardware. Applications choose the extension packages in addition to the core package they need to use to accomplish the desired tasks of the application. Each JTAPI extension package has its own specification describing its extensions to the telephone class java API, and in most cases has its own separate overview document describing it.

The chart below lists each extension package available, with a link to the individual overview document, if it exists. These objects are defined using Java interfaces in the core package. Each call model object represents either a physical or logical entity in the telephone world.

The primary purpose of these call model objects is to describe telephone calls and the endpoints involved in a telephone call. These call model objects are related to one another in specific ways, which are summarized below and described in more detail in the core package specification.

A description of each object follow the diagram. The Provider object is an abstraction of telephony service-provider software. Telephone class java Provider hides the service-specific aspects of the telephony subsystem and enables Java applications and applets to interact with the telephony subsystem in a device-independent manner.

The Call object represents a telephone call, the information flowing between the service provider and the call participants. A telephone call comprises a Call object and zero or more connections. In a two-party call scenario, a telephone call has one Call object and two connections. A conference call is three or more connections associated with one Call object, telephone class java. The Address object represents a telephone number. It is an abstraction for the logical endpoint of a telephone call.

Note that this is quite distinct from a physical endpoint. In fact, one address may correspond to several physical endpoints i. A Connection object models the communication link between a Call object and an Address object. This relationship is also referred to as a "logical" view, telephone class java, because it is concerned with the relationship between the Call and the Address i. Connection objects may be in one of several states, indicating the current state of the relationship between the Call and the Address.

These Connection states are summarized later. The Terminal object represents a physical device such as a telephone and its associated properties.

Each Terminal object may have one or more Address Objects telephone numbers associated with it, as in the case of some office phones capable of managing multiple call appearances. The Terminal is also known as the "physical" endpoint of a call, because it corresponds to a telephone class java piece of hardware.

TerminalConnection objects model the relationship between a Connection and the physical endpoint of a Call, which is represented by the Terminal object. This relationship is also known as the "physical" view of the Connection in contrast telephone class java the Connection, which models the logical view.

The TerminalConnection describes the current state of relationship between the Connection and a particular Terminal. The states associated with the TerminalConnection are described later in this document. The core package defines telephone class java methods to support its primary features: placing a telephone call, answering a telephone call, and disconnecting a connection to a telephone call.

These methods are Call. Once an application has an idle call object obtained via Provider. The application must specify the originating Terminal physical endpoint and the originating Address logical endpoint on that Terminal in the case that a Terminal has multiple telephone numbers on it, telephone class java. It also provides the destination telephone number string.

Two Connection objects are returned from the Call. Applications monitor with listeners discussed later on Terminals for when incoming calls are presented. At that time, applications may invoke the Telephone class java. The Connection. The Connection object represents telephone class java relationship of that Address to the telephone call. In the core package, application may only remove entire Addresses from the Call, and all of the Terminals associated with that Address which are part of the call are removed as well.

The call control extension package provides the ability for application to remove individual Terminals only from the Call. A Connection object is always in a state that reflects the relationship between a Call and an Address. The state in which a Connection exists is not only important to the application for information purposes, it is always an indication of which methods and actions can be invoked on the Connection object. The state changes which Connection objects undergo are governed by rules shown below in a state transition diagram.

This diagram guarantees to application developers the possible states in which the Connection object can transition given some current state. These state transition rules are invaluable to application developers. The diagram below shows the possible state transitions for the Connection object, telephone class java. Following this diagram is a brief summary of the meaning of each state.

Connections typically transition quickly out of the IDLE state into another state. A Connection in the IDLE state indicates that the party has just joined the telephone call in some form.
