Abstract-- Many Interactive Voice Response (IVR) systems use
the popular VoiceXML standard for managing vocal dialogs. For
call control aspects, such systems often use the Session Initiation
Protocol (SIP) or a similar protocol. W3C is currently developing
a new Call Control eXtensible Markup Language (CCXML)
standard, at a higher abstraction level than SIP and which could
hide the latter in order to accelerate the development of complex
VoIP solutions that have an IVR component. But will this really
be the case? This paper presents a comparative study base on a
simple Personal Assistant system. Although there are undeniable
benefits to a CCXML-VoiceXML approach, many observations
and lessons lead us to believe that developers will face several
limitations and potential pitfalls.
