If a delay is specified, the event is not delivered to the target CCXML session until the delay time has elapsed. This script is actually allowed and the assignment to x will be completed without error.

However on a platform where the actions are optimized into a single ECMAScript execution block something like the following code would actually be executed instead:. The state of the Connection Object is unchanged by this request.

All you need to do is write the application’s XML, map it to a phone number in the Voxeo Application Manager, and give it a call. Several examples of left-hand-side expressions are as tutorila left-hand-side expression in red:.

The following is the list of changes made to this document at each stage of the Recommendation Track process. All other content is only accessible via the content attribute of the fetch. This property is a URI which addresses the interpreter platform; for an incoming call, this is the called URI; for a redirected tutkrial call, this is also the most recent redirection, and the prior values are contained in the “redirect” property; for an outgoing call, this is the calling URI.

It is designed to be suitable for running on a server where users may not be allowed to execute arbitrary programs, and so is not Turing-complete.

Note that the Connection Object state is current tutoriao of the event currently being processed, but may ccmxl reflect events that are currently queued, or other events that occur before the request generated tutofial an element is processed; therefore, not all failures caused by the uttorial of the actual connection will result in error.

W3C’s role in making the Recommendation is to draw attention to the specification and to promote its widespread deployment. This property is a protocol-dependent property which allows further refinement of the state of a Connection, if desired. This event MUST be generated when a request to accept an incoming connection cannot be completed.


Which topic are you interested in? 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. They can be created only by assigning a value to a property of the application object application.

A full bridge is ccxnl between connections c2 and c3, connection c1 is still receiving from c2. Each instance is uniquely identified by its connection identifier. There were no changes since the Proposed Recommendation document. If the dialog was ccxxml without a conference, the value must be undefined.

From the caller’s cccml, this state is when the phone is ringing and waiting to be answered:. The request requires user authentication. 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.

While any event name is possible, there is a small set of well-known events that are generated as a matter of course, and which any telephone application should handle.

Call control includes handling incoming calls, placing outgoing calls, bridging or conferencing multiple call legs, and ultimately disconnecting calls. This event MUST be emitted when an incoming or outgoing call fails to complete its connection.

To avoid conflict with standard event attributes, payload parameters with the name ” eventid ” or ” eventsourcetype ” are ignored. After the dialog is bridged to a connection, VoiceXML session variables are not updated again. This document has been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and is endorsed by the Director as a W3C Recommendation.

Events injected into an active CCXML session by the ” basichttp ” processor provide the standard event attributes as described in Section 9. The character string returned is interpreted as a time interval. The identifier of the connection to which the dialog connection is bridged usually the connectionid that was specified in the dialogstart or dialogprepare.

The event may then be handled by a transition such as:. A description of the reason the operation failed. The value of the exit expr attribute.

The dialog environment determines how passed parameters will be handled. The usage of label is platform-dependent. Variables in this scope can be also created without an explicit declaration by assigning a value to a property of ccxmml transition object transition. You’ll want to download the source code at the bottom of the tutorial and put the files unzipped on a publicly accessible Web server. If the connectionid attribute is omitted, the interpreter must reject using the id indicated in the current event being processed.


CCXML provides a powerful and flexible method of creating multi-party calls based on the following concepts:. The ordering of the id1 and id2 attributes is as specified in The ECMAScript object returned contains information which may be used by the implementing platform when establishing the outbound connection.

Any such code likely relies on unusual ordering of variable declarations and assignment statements or the use of confusing variable names and scopes; such code is discouraged due to its potential for producing unintended results.

If the dialog was prepared without a connection, the value must be undefined. This property must be set to the ECMAScript string value of the name of the element that produced the error ie acceptrejectetc. Platforms are responsible for clearing out unused fetch resources, and may impose limits on the resources that can be fetched by a single session.

Once you’ve got the debugger open, give your application a call. A recommended set of generally applicable metadata properties e. This element instructs the implementation to allocate a Conference Object using the specified options. If the event targettype specified is not supported the platform MUST throw a error.

Figure A and Figure B illustrate the session life-cycle of several different scenarios. Platforms MAY choose to add properties to events.

A Valid The developer may also specify a URI value which points to a user-defined wav file to be played instead of the default system beep. The ID of the event source referenced either directly via the source attribute or indirectly via the event attribute of the move element.

If a session receives a ‘ conference.
