The publication of W3C standard languages, such as VoiceXML and CCXML, has dramatically changed the speech application design process. This session discusses some of the efforts to extend and validate the use of standard languages. Learn how the call control language can work with SIP and VoIP to implement an extensible SIP softswitch. Discover how the VoiceXML Forum’s certification program has impacted the cross-vendor interoperability of VoiceXML by VoiceXML platform vendors.

Developers are increasingly using the W3C Call Control language, CCXML, to add call control features to their telephony applications. At the same time, Session Initiation Protocol (SIP) and Voice over IP (VoIP) have found widespread acceptance and deployment in everything from long distance networks to enterprise call centers and in consumer telephony. Learn how SIP, VOIP, and CCXML can work together in next-generation telephony deployments, plus the advantages and disadvantages of a combination of both. Learn how CCXML can be used to implement an extensible SIP softswitch.

VoiceXML platform certification has helped to stabilize and mature the speech and contact center industry by encouraging the cross-vendor interoperability of platforms, tools and applications. Along the way, certification has become a key speech system RFP criterion for savvy companies adopting speech. This presentation will discuss why VoiceXML platform certification is an indispensable requirement of a complete speech system specification. This presentation will also detail the pitfalls that customers may encounter in choosing self- or vendor- certified platforms. A summary of what is covered and what is not covered by the VoiceXML platform certification will be presented.
