VoiceXML 2.1 Development Guide

<disconnect> element

The disconnect element is used to programmatically disconnect the caller from the voice application, which also throws an connection.disconnect event to the interpreter to allow the the developer to submit any existing variables to his webserver.

usage

attributes

namelist	Data Type: NMTOKEN	Default: Optional
	The namelist attribute allows developers to send the browser variable information upon an exit condition. Currently, the VXML browser does not do anything with the namelist value, but it does allow you to pass the values to any originating CCXML application. Here is an example of the catch of a hangup event in VXML: `<catch event="connection.disconnect.hangup"> <exit namelist="SomeVar"/> </catch>`

Hello...

I want to pass the value from vxml to ccxml during the disconnect the call.

Please tell me how to pass the value from vxml to ccxml during disconnect.

Hello Amit,

I am assuming you should be able to do what you need if you catch the hangup in your VXML code. When you catch the hang up you can do the dialog exit or return to return the variables that you want to the parent CCXML session.

Here is an example of the catch of a hangup event in VXML:
[code]<catch event="connection.disconnect.hangup">
<exit namelist="SomeVar"/>
</catch>[/code]

Depending on how your VXML is coded you may want to put this in your root document or a leaf document depending on what you want to do.

If you have any questions, please let us know.

Best Regards,
Joyce Chang

It seems that <disconnect> has a namelist attribute. So, params could be passed back directly to underlying platform.

See ref down below

Hello,

Thank you. It looks like that got dropped from the documentation somehow. I've noted this to our documentation team.

Thanks for letting us know. The namelist attribute was certainly missing! I've added it to our VoiceXML docs!

Have a great day.
