CCXML SPECIFICATION PDF

With this latest revision, our main priority was to resolve unclear or incomplete areas of the CCXML specification. During this process several sections of the. The CCXML specification defines both a state machine and event handing syntax and a standardized set of call control elements. This tutorial implements the CCXML specification that was used for the CCXML is a new language, so new that the W3C specification has not.

After the dialog interaction is complete, an asynchronous event is sent to the CCXML session which can use any results returned by the dialog environment to decide what should happen next. However, the two languages are separate and are not required in an implementation of either language.

The http-equiv attribute has a special significance when documents are retrieved via HTTP. This property is a URI sepcification addresses the remote device; for an incoming call, this is the calling URI; for a redirected incoming call, this is the requester of the most recent redirection, and prior values are contained in the “redirect” property; for an outgoing call, this is the called URI.

The name has the value of the ” name ” parameter. If the application needs access to the content outside of the fetch. When each one of them joins the conference he is told how many people are there in the conference and those already in the conference are informed about a new entrant to the conference.

If a conference already exists the platform must return the conference identifier of the previously created conference. This property is a reference to an object defining protocol information for the protocol used on this connection; the referenced object defines information which applies to all connections using this protocol, and it has at least two properties: In the example the parent assertion is “17” and the children are: When the delay has elapsed the event is spwcification at the tail of the queue.

The method of the message passing is up to the platform but it is assumed that there is some basic capacity in place. Reason that the session ended.

Dialogs are also modeled internally as a Connection for the purposes of media interaction. If the dialog was being connected to a connection the value must be undefined. Other payload parameters are exposed as properties of session. The value of the attribute must receive an internally generated unique string identifier to be associated with the event being sent. The array is associative sprcification each key in the array is the connection identifier for the Connection.

Many of specificatioon most valuable benefits of both technologies are found at the intersection of the two: The ECMAScript object returned contains information which may be used by the implementing platform or passed to the network disconnecting the connection.

The event source associated with this identifier must be moved to the target session.

If the call is currently joined, it MUST be unjoined before the redirect is performed and a conference. This event is sent to the parent session and specifiction the exiting.

A Connection is an object modeling a resource by which two independent unidirectional media streams, and optionally any associated network signaling traffic, can be controlled by a CCXML session.

Do they work well together? After the dialog is bridged to a connection, VoiceXML session variables are not updated again.

The application answers an incoming phone call and then connects it to a VoiceXML dialog that returns a value that is then logged to the platform Example2. This document includes comment elements specificafion content may be included in a log element in the response document to aid in debugging.

The only exception to this rule is when ccxml. It runs on a thread separate from the VoiceXML dialog. This specification describes markup for designed to provide telephony call control support for VoiceXML or other dialog systems. Bridges can be either one-way, in which the media stream flows only from party A to party B such that B can hear A, but A cannot hear Bor two-way, in which the media stream flows in both directions between the parties involved.

The CCXML session is notified when the dialog operation successfully completes, or fails, by an asynchronous event. If this attribute is present, it must evaluate to true for the transition to be selected. If the connectionid attribute is omitted, the interpreter must reject using the id indicated in the current event being processed.

VoiceXML Review – Features – CCXML Update

The new CCXML session has no relation to its creator once spawned, and has a wholly separate lifetime and address space. It has been designed to meet the needs of resource-constrained environments.

If specified, the dialog being prepared MUST be joined to the referenced conference as specified by the mediadirection attribute. If the connectionid attribute is omitted, the interpreter must redirect using the specifjcation indicated in the current event being processed.

Variables declared specificatiin this manner are declared in the scope of the closest containing scope CCXML element. Conferencing Enhancements CCXML has now significantly expanded support for multiparty conferences, including support for conference resource reservation and enhanced media processing. In our “hello world” example Example1. The application may obtain the unique identifier for a fetch request by providing an ECMAScript left-hand-side expression in the fetchid attribute when the fetch is performed.

The identifier of the connection to which the dialog connection was attempting to be prepared usually the connectionid that was specified in the dialogprepare.
