VXML browser cannot stop the execution of the audio node, when audio file from the previous node is missing.

Problem Summary When the audio node is executed, the VXML broswer tries to fetch the audio file and simultaneously posts a HTTP request to the new document as well. In Response, the VXML Server returns the next VXMLDocument(which has TTS string to play). As a result the VXML browser gets a badfetch from the Media Server and sends a POST HTTP request with the errorType as bad.fetch to the VXML server.

Also,the HotEvent defined in the application for badfecth throws VXMLDocument(Error.wav) and results in the call being disconnected.

Error Message/Symtom Hotevent document is not executed, and as a result call never drops as expected and goes on.
Possible Cause The nature of the VXML browser is such that once the VXML document starts processing, it cannot be interrupted. This results in the VXML document being executed before the next node which will eventually drop the hotevent VXML document.
Recommended Action Use a dummyObject which will halt the execution of the browser until object tag finishes. This ensures that the interpreter sends 404 badfetch in the POST request and will process the Hotevent instead of the next node.
Release CVP 8.0 ESxx. onwards
