Introduction to CCXML, Part II

Any other interaction takes place through the event mechanism. It is not possible to start a dialog that is not joined to a connection or a conference. A connection is typically shorter than a session. All Connection instances have a set of properties in common, shown in the following table.

The properties of the event indicate the actual reason for the disconnection. The debugger shows your application’s activity in real-time, allowing you to monitor its progress and debug any errors it might throw.

A Conference is an object that controls the mixing of media streams for two or more Connections through Bridges. An instance of the Connection Object is associated with each telephony event source.

On the following screen, select the platform type that you chose in Step 2 above. Information provided by the protocol prior to connection is accumulated and stored with the identified Connection object. A description of the reason the merge failed. A list of current W3C publications and the latest revision of this technical report can be found tutoriaal the W3C technical reports index at http: Variables defined in the session scope are subject to the parent scope chain delegation model but do not have a parent scope defined.

Each running CCXML interpreter has a queue, into which it places incoming events, and sorts them by arrival time.

tutrial 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.

Telephone applications need to receive and process large numbers of events in real-time. Which topic are you interested in? CCXML sessions can also send events to themselves. The exiting document will be identified on the exit event by its session ID.

If however the dialog cannot be prepared for any reason, an error. A semantic error in the application, such as the use of an invalid ECMAScript expression, preventing the element from being executed. It is important to note that because CCXML is fully asynchronous, and because events can occur on the underlying communications network at any time, that connection-related events can occur that are not related to application actions.

When the fetch request has been completed, an event is generated against the session that initiated the fetch.

Receipt of the event does not imply the event has been processed by the receiver but simply that it has been sent without error. The identifier of the connection to which the dialog connection is ccxkl usually the connectionid that was specified in the dialogstart or dialogprepare. If specified, the dialog being prepared MUST ccxmo joined to the referenced connection tutoial specified by the mediadirection attribute. This event is generated when a CCXML session is terminated for any reason, if the terminated session has a parent session.

Due to how ECMAScript var statements work, declarations are applied before assignments no matter where they are placed in the code.

If the dialog was being connected cxxml a conference the value must be undefined. If both id1 and id2 specify dialogs and the platform does not support joining together two dialogs, then an error. The request is analyzed by the ” basichttp ” event processor, resulting in. 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.


The downloadable version of this article contains all of the code examples in easy to use text files. Note that the value of the src attribute must not be an ECMAScript expression in order to allow it to be resolved at compile-time.

An ECMAScript expression which returns the value of the event identifier that was received when the send command was issued. If at anytime a ccxml. Implementations may use additional HTTP parameters specifically to address security. 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.

Execution of this element connects a dialog environment to a tutrial and instructs it to start interacting with the caller. Inbound call to your voice application Outbound call from your tutodial application. These events are detailed in section 9. Tutogial returned from the dialog tytorial relating to the dialogs transfer request. This attribute must not be specified in conjunction with the src attributeotherwise ignored.

futorial Implementations may support other event injection processors so long as they do not have the type ” basichttp ” which is reserved for the processor described in this section. In the picture below, the connections c1 and c2 are joined in a full duplex mode to the conference C1.

Event types are dot-separated strings of arbitrary length. After the dialog is bridged to a connection, VoiceXML session variables are not updated again. A description of the reason the dialog wants the transfer to be terminated. For more information about connections and bridges, refer to Section If the event source can receive events, you can use this in the targettype attribute of send. This event MUST be generated when a request to reject an incoming connection cannot be completed.

All error events are named with the prefix “error.
