In addition to the standard event attributes detailed in Section 9.

Voxeo offers two voice application platforms: Two connections were merged successfully as requested by the application. The scope in which the variable is defined must be determined from the position in the document at which the variable is defined. This event MUST be generated when a request to reject an incoming connection cannot be cvxml.

The fields of this event are shown below. A semantic error in the application, such as the use of an invalid ECMAScript ccxml, preventing the element from being executed.

The specification will change. The parameter value is the variable value after being converted into a string. For example, if a dialog. If a platform supports delivery of multiple inbound calls to a single session, the way this is configured is implementation specific. This attribute must not be specified in conjunction with the src attributeotherwise ignored.

They exist while the document is loaded. At the Application Settings page, you’ll give your application a name, and enter in the publicly accessible URL for your voice application code in the Start URL 1 field. CCXML may also receive events from Connection and Conference Objects, in the case of line signaling, line-status informational messages, or error and failure scenarios. Indicates the new value of the variable. One session can span multiple documents and phone calls.

The following table shows the events that reflect the outcome of the connection-oriented elements defined by CCXML, for this reason the table omits the event generated by the underling network i. Due to this difference in behavior between line by line vs batch execution application developers SHOULD NOT depend on the ability to declare variables out of document order and SHOULD write code such that its behavior is the same whether executed line by line or in a batch.

Our editors highlight the TechRepublic articles, galleries, and videos that you absolutely cannot miss to stay current on the latest IT news, innovations, and tips.

Such variables include session information such as a session identifier, the reason for what the session was started, list of all Connection objects, and so on. The philosophy in this regard has been to “make simple things simple to do. The identifier of the connection to which the dialog connection is bridged usually the connectionid that was specified in the dialogstart or dialogprepare.

In many cases this may be perfectly acceptable and the CCXML application may be able to successfully recover from the error.

Note that when the xmlns attribute is used alone, it sets the default namespace for the element on which it appears and for any child elements. In particular, it is designed to facilitate prior compilation for execution in a lightweight environment.

When a VoiceXML dialog is bridged to a connection with an associated call leg, the standard VoiceXML session variables obtain their values from the call leg.

If the dialog was being connected to a connection the value must be undefined. An ECMAScript expression that returns a character string that must be used to play a tone or a custom wav file to the conference participants when this Connection joins. This is discussed in Section This event MUST be emitted to indicate that a connection has been successfully merged with another connection at the network level, and is therefore disconnected from the CCXML application.

Each named variable will be created as a property of ‘session.

The relationship between these scopes is shown below. These are not only life-cycle scenarios; sessions can also have multiple sequential connections, or even have multiple concurrent connections. The following state diagram shows the major aspects of Connection behavior, but omits some detail in favor of clarity e. The fields in this event are:. A description of the reason the operation was denied.

Unlike other events, the ccxml. Some telephony call control definitions do not define a separate Conference Object, instead defining a conference simply as a call with more than two parties. The exiting document will be identified on the exit event by its session ID.

Dialogs are also modeled internally as a Connection for the purposes of media interaction. This event is thrown once the document is parsed and ready for execution document initialization occurs between the fetched and loaded events. When a VoiceXML dialog is bridged to a connection with an associated call leg, the standard VoiceXML session variables obtain their values from the call leg.

If the media endpoint does not have any media destinations the length of the array MUST be 0. This document has been produced as part of the Tuorial Browser Activity.

The ECMAScript object returned contains information which may be used by the implementing platform or passed titorial the network redirecting the connection. Call control includes handling incoming calls, placing outgoing calls, bridging or conferencing multiple call legs, and ultimately disconnecting calls.

A SIP URI is provided as the originators caller id, a selection of protocol specific parameters are provided callingDevice and callCharacteristics and a string of application specific data is provided to be presented to the remote endpoint. For example, if the tutoroal party on Connection A is initially interacting with Dialog D i.

Indicates the new value of the variable. This call must be rejected. See Section 10 for a discussion of connections and bridges. Session was started due to a external session launch request. A description of the reason the dialog could not be started.

These events are detailed in section 9. Examples of such applications include: The first partition in document order with a cond that evaluates to true is selected.

The ID of the send event that has been cancelled as specified in the sendid attribute of the cancel element. Since conferences are global in scope, it is possible that other sessions will establish or terminate bridges to a Ccx,l created by an application. The fields of this event are shown below.

If neither attribute is specified or both attributes are specified, an error. Refer to the discussion of bridging in Section Event names are case-insensitive. In the case of an external session launch the session will not own any event endpoints.

Now let’s have a look at some real examples and try to understand what is done there. Eventsand The method of the message passing is up to the platform but it is assumed that there is some basic capacity in place. In the created session, session. It is delivered to the document which issued the request and indicates that the new session has not been created.

JCC was designed to be a cross-platform high-level event set to describe as generic a phone model as possible.

Each connection state constant can be used to index into this array to return the human-readable string corresponding to that constant. In the context of CCXML, it was felt that the Address, Call, and Provider objects would add more complexity than value, so these were omitted as explicitly visible objects.

Additionally, this call model is small and easily-understood so that tutogial example programs can be written. The identifier of the connection to which the dialog connection is bridged usually the connectionid that xcxml specified in the dialogstart or dialogprepare.

In VoiceXML this would be the values of each of the objects listed in the exit element’s namelist. The authors of this document are participants in the Voice Browser Working Group. If you run into any problems with your application, use the Application Debugger’s built-in support feature send a copy of your logs to our Extreme Support team. The event may then be handled by a transition such as:. The ECMAScript object returned contains information which may be used by the implementing platform or passed to the network when merging the two connections.

Voice Browser Call Control: A Conference is an object that controls the mixing of media streams for two or more Connections through Bridges. Variables in this scope can be also created without an explicit declaration by assigning a value to a property of the transition object transition.

These diagrams do not show all possible scenarios but rather show some of the most common ones that CCXML applications may encounter.

This is called document initialization. This event must be emitted when an incoming connection is accepted successfully, or as when an outgoing connection is answered. The platform MUST implicitly tear down any existing bridges to the connections and send a conference. They can gutorial created only by assigning a value to a property of the application object application.

If the connectionid attribute is omitted, the interpreter must disconnect using the id indicated in the current event being processed. The system identifier may be modified appropriately. Many of the network environments in which a CCXML implementation may be expected to operate provide facilities by which two existing calls can be merged into tuyorial single call at the network level.
