CCXML Elements

Although the CCXML language is fully supported, Blueworx Voice Response for Linux does not currently implement the complete set of CCXML elements. Table 1 describes the level of element implementation that is available in this release, and shows the attributes that are implemented for fully and partially implemented elements.

If an element attribute that is not implemented by Blueworx Voice Response is used within a document, the document loads successfully but the event error.unsupported is thrown if the unsupported element is executed.

Table 1. Summary of CCXML elements and attributes
Element	Description	Level of Implementation	Implemented Attributes
<accept>	Accepts and connects an incoming phone call.	Full	connectionid hints
<assign>	Assigns a value to a variable.	Full	name expr
<cancel>	Cancels a CCXML event timer	Full	sendid
<ccxml>	Defines the start and end of a CCXML document.	Full	version xml:base
<createcall>	Makes an outbound call.	Partial, following not implemented: aai callerid When an attempt is made to use an unsupported feature of <createcall>, a `connection.progressing` event is generated.	connectionid callerid for SIP calls dest hints joinid joindirection timeout
<createconference>	Creates a multi-party audio conference.	Partial - reservedtalkers and reservedlisteners may be set but don't do anything	conferenceid confname reservedlisteners reservedtalkers hints
<createccxml>	Creates a new CCXML session in a new thread.	Full	next namelist fetchparam parameters method sessionid timeout maxage maxstale enctype
<destroyconference>	Tears down a multi-party audio conference.	Full	conferenceid hints
<dialogprepare>	Prepares the dialog handler. When dialog preparation completes successfully, a `dialog.prepared` event must be posted to the event queue of the CCXML session. If the dialog cannot be prepared for any reason, an `error.dialog.notprepared` event must be posted. If the dialog is terminated using `<dialogterminate>` while it is being prepared a `dialog.exit` event must be posted. The MIME type specified by the HTTP headers must match that specified by the `<dialogprepare>` `type` attribute.	Partial conferenceid not supported	connectionid parameters src type namelist dialogid mediadirection `='both'` maxage maxstale enctype method hints
<dialogstart>	Runs a dialog session. The `<dialogstart>` attributes must match those specified in any associated `<dialogprepare>`, otherwise an `error.dialog.notstarted` event is thrown and opening the dialog is canceled.	Partial conferenceid not supported	connectionid prepareddialogid src type - For BVR specific type see: Watson integration, Google integration or Amazon Lex Integration namelist dialogid maxage maxstale mediadirection `='both'` parameters enctype method hints
<dialogterminate>	Stops a dialog session.	Full	dialogid immediate hints
<disconnect>	Causes a near end hangup.	Full	connectionid reason hints
<else>	Used in `<if>` elements.	Full
<elseif>	Used in `<if>` elements.	Full	cond
<eventprocessor>	Block of event processing	Full	statevariable
<exit>	Ends and returns from the CCXML session. If no value for the `expr` attribute of the `<exit>` element is defined, the value of the `expr` attribute of the parent's `ccxml.exit` event is `undefined` .	Full	expr namelist
<fetch>	Preloads a CCXML, ECMAScript, or JavaScript file.	Full	next type namelist method fetchid timeout maxage maxstale enctype processed
<goto>	Launches a new CCXML document in the current CCXML session. Throws an `error.semantic` event if: Called before a fetch completes fetchid is invalid The CCXML of the fetched document is invalid	Full	fetchid
<if>	Conditional logic.	Full	cond
<join>	Connects two audio sources	Partial, following not implemented: entertone exittone autoinputgain autooutputgain toneclamp	id1 id2 duplex dtmfclamp hints (dtmftransmitclamp)
<log>	Logs to the platform debug log.	Full	label expr
<meta>	A container for referencing information about a CCXML document.	Full	name content http-equiv
<metadata>	A container referencing in a metadata language the CCXML document information.	Full	None
<move>	Moves an event source to another CCXML session. On error, throws an `error.move` event, except for where event and source are both specified, when an `error.fetch` event is thrown.	Full	source event sessionid
<redirect>	Redirects an incoming call to a new endpoint.	None
<reject>	Rejects an incoming phone call.	Full	connectionid reason hints
<script>	Runs ECMA script.	Full	src fetchid timeout maxage maxstale charset
<send>	Generates an event.	Partial xmlns:prefix not supported	target targettype sendid delay name namelist hints
<transition>	Specifies the action to be taken when a matching event is processed.	Full	state event cond name Although the `name` attribute is still supported, all `<transition>` elements are now automatically allocated an `event$` ECMAScript variable that holds identity information if name is not specified.
<unjoin>	Disconnects two audio sources.	Full	id1 id2 hints (note: no supported information currently defined)
<var>	Declares a variable.	Full	name expr
