	Between Speech and Call Control Applications

From CCXML to speech application you use the namelist in the dialogprepare or dialogstart tag to pass values to a speech application from a ccxml application. In the speech application you would use the Capture Expression to store that into a Dialog Designer variable.

If the namelist in CCXML is namelist="myvar myothervar" /> then the expression in the speech application to access the passed in value is session.connection.ccxml.values.myvar and session.connection.ccxml.values.myothervar.

To pass data back to the CCXML application, use add an output parameter to the return. The returned values show up in CCXML in dialog.exit event event.values.*.

For the dialog.exit event, if dialogresult and numbertocall returns in the transition, you can acess the return values as folows:

<transition event="dialog.exit" name="evt" state="in_dialog">  <log expr="' dialogresult : ' + evt.values.dialogresult"/>  <log expr="' numbertocall : ' + evt.values.numbertocall"/> ... ... ...
