ccxml elements - destroyconference

CCXML 1.0-W3C Development Guide

<destroyconference> element

The <destroyconferenece> element is used to tear down a conference object that was instatiated using the <createconference> element. Upon completion of this operation, an asynchronous event will be sent to the CCXML document notifying the application that the conference has indeed been destroyed.

usage

<destroyconference conferenceid="(ECMAScript Expression)" hints="(ECMAScript Expression)">

attributes

conferenceid	Data Type: (ECMAScript Expression)	Default: Required
	The conferenceid attribute defines the ECMAScript string value that is the identifier of the target conference to be destroyed. If the attribute value is invalid, then an error.semantic event will be thrown to the CCXML interpreter.
hints	Data Type: (ECMAScript Expression)	Default: Optional
	The hints attribute can be used to specify information used by the platform to configure the event processor. The value of this attribute should equate to an object that contains an array property of "headers"; for instance: `<script> var Hints = new Object(); Hints.headers = new Object(); Hints.headers['x-mySipHeader'] = 'hello world'; </script>` Note that 'hints.headers' stores what headers to add to the sip request, and that only headers starting with an 'x-' prefix are sent.
