Is Hastenix a full-blown VoiceXML browser for the Asterisk?
No, not approximately. HAWHAW’s VoiceXML output uses a rather small subset of the VoiceXML complexity, and even not all HAWHAW elements are fully supported yet. If you have a running VoiceXML application deployed at a professional VoiceXML provider’s site, chances are poor that you get your application running on your Asterisk by means of the Hastenix script. The term “Hastenix” is german slang and means “You have nothing”. In fact you have much more than nothing, but don’t expect to get a standard-compliant VoiceXML browser.
