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.

If a platform does not support removal of tones, it must ignore this attribute.

Call Control eXtensible Markup Language – Wikipedia

Event Details Error Handling Execution Model And last – but not least – we reworked several areas in the interest of overall consistency: An ECMAScript expression which returns a character string setting the value of the HTTP Accept header to tell the application server what content type the application wishes to have specificcation. If the event source can receive events, you can use this in the targettype attribute of send. Such functionality is especially valuable for outbound specifiation – such as an appointment reminder service – where any delay after answering but before prompt playback is uncomfortable for the call recipient.

Note that this does not imply that the underlying conference has necessarily been destroyed, since there may be other specifocation attached to that conference.

CCXML 1.0 Implementation Report Plan

Errors that occur in trying to load and compile a CCXML specificarion, such as the inability to fetch the CCXML page or statically referenced ECMAScript content, XML parsing or validation errors Including checks for mutually exclusive attributes or any other constraints as defined in the this specification, it’s attribute tables, schema or DTDcompilation errors or other errors that occur as speciifcation result of trying to fetch and run a CCXML page prior to document initialization.

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


If specificatkon CCXML application knows that it is going to have 20 participants in a conference, it can use this attribute to ensure all required resources are available to handle all 20 callers. The order connectionid1 vs.

Cover Pages: Voice Browser Call Control (CCXML)

If executed line by line this would end up executing every line in the script and declaring a transition scoped variable named id with a value of 2. If the event is not caught the session will be terminated and all active connections, conferences and dialogs that are owned by that session will be automatically terminated by the platform. An ECMAScript expression which returns a string of application-to-application information to be passed to the destination endpoint when establishing the connection.

For example, a parameter named “a.

Meanwhile, the VoiceXML dialog can interact with the user, undisturbed by the incoming flow. For security purposes, transformed IRCGI documents are deployed to an isolated directory, named “cgi-bin” under the assertion directory.

The scope of these language features is for controlling resources in a platform on the network edge, not for building network-based call processing applications in a telephone switching system, or for controlling an entire ccdml network. Implementers MAY define and support any platform-specific events they like. If the attribute value is invalid, an error. When the fetch request has been completed, a fetch.

When ‘ id1 ‘, ‘ id2 ‘, or both reference to a Conference, the ‘ conference. These events arrive from outside the program itself – either the underlying telephony platform, or from other sources of events.

An ECMAScript expression which returns a string that is the id of a call leg that must be disconnected.

A Connection Object must have a connectionid property which is the ECMAScript string value of the Connection identifier, which uniquely identifies each instance of the Connection object. If specified, the dialog being started MUST be joined to the referenced conference as specified by the mediadirection attribute. A description of the reason the reject failed. These components are designed to integrate specificatiom with existing language elements for defining applications which run in a voice browser framework.


Variables defined within the application scope are visible to all documents within the CCXML application. Return values from the dialog. If for any reason the implementation is unable to create the Conference Object using the specified options it MUST fail with a error. Otherwise, the next document is ” fail. There are two versions of this event: This is true even if the actual connection has already been terminated, with a ‘ connection.

Similarly apecification someone hangs up, the fact that a conference participant has exited is announced. The value of the attribute must receive a specificatioj identifier value for the launched dialog interpreter instance.

The access URI may also be specified in an implementation-specific manner for example, product documentation. Execution of the current document terminates. This information may consist of protocol-specific parameters. The next document must continue the test and must determine the success or failure of the test. This automated system asks who the caller is, and records the audio. Due to how ECMAScript var statements work, declarations are applied before assignments no matter where they are placed in the code.

The ECMAScript object returned contains information which may be used by the implementing platform or passed to the network when the two specified Connections, Dialogs or Conferences id1 and id2 are joined. If the platform does not support the specification of callerid it must raise a connection.

They are visible only within that document. Such identifiers are not locally meaningful to the session receiving the event although they can still be used for logging or other purposes.
