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.

This event must be emitted when an incoming connection is accepted successfully, or as when an outgoing connection is answered. The components as shown in the figure below represent logical functions, and are not meant to imply any particular architecture.

Signaling System 7 [ SS7 ]. This will enable application developers to use markup to perform call screening, whisper call waiting, call transfer, and more. Note that this should not be taken to preclude platform-level optimizations or caching of resources that are fetched multiple times. 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 a single call at the network level.

If the named conference does not exist, the platform must create a conference object as requested and return the value of the conference identifier to the variable specified in the conferenceid attribute. The identifier of the session which issued the createccxml to start this document. There are two exceptions to this behavior: Identifies the scope and impact of the semantic error; this attribute MUST be set to one of the following string values: Overview With this latest revision, our main priority was to resolve unclear or specificagion areas of the CCXML specification.

This property must be set to the ECMAScript string value of the name of the element that produced the error ie acceptrejectetc. Variables defined in the session scope are subject to the parent scope chain delegation model but do not have a parent scope defined.

This event MUST be generated when a request to accept an incoming connection cannot be completed. If the connectionid attribute is omitted, the interpreter will disconnect using the id indicated in the current event being processed. The duplex attribute determines whether the join must establish a half-duplex unidirectional or full-duplex bi-directional bridge.

The default is Ok. The entrance criteria for the Proposed Recommendation phase requires a minimum of two independently developed interoperable implementations for each required feature, two or more implementations of optional features that would impact interoperability, and a minimum of one implementation for each optional feature that has no impact on interoperability.

The ECMAScript object returned contains information which may be used by the implementing platform or passed to the network when merging the two connections. Previously, such applications have been developed on proprietary call control platforms that were built specifically for the call control application at hand.

The ID of the target session to which it was attempted to move the event source. Variables in the application scope are subject to the parent scope chain delegation model and have session spefification their parent scope.

The document generated when include is false may contain the content of comment elements that were encountered. The same conference Speciification will be returned in each case, allowing this to be used as a mechanism for looking up conference IDs. If the dialog was prepared without a conferencethe value must be undefined.

Examples of events are incoming phone calls, dialog actions or user defined events. This will be done in conjunction with other W3C working groups, including the proposed new Multimodal working group.

Main concepts and terms CCXML can be used as a third-party call control manager in any telephony system. Other documents may supersede this document.

The conference name corresponds to the conference identifier that will be returned in the variable speckfication in the conferenceid attribute. 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. Valid only when the value of the method is “post”otherwise ignored.

However, it is permissible for speicfication CCXML implementation to optimize session changes by “lazy-binding” values as they are accessed or evaluated by a CCXML program, so as to minimize processing time. An ECMAScript expression which returns a string that is the identifier of the first connection that is to be merged. The eventid is a unique string identifier of the event generated by the ” basichttp ” processor.

If the application needs access to the content outside of the fetch. Note that this does not imply that the underlying conference has necessarily been destroyed, since there may be other sessions attached to that conference. In the picture below, the connections c1 and c2 are joined in a full duplex mode to the conference C1.

This property must be set to the ECMAScript string value of the printable error ccxmp associated with this error. Several elements within this specification define a hints attribute.
