Call Control eXtensible Markup Language (CCXML) is an XML standard designed to provide asynchronous event-based telephony support to VoiceXML. Its current status is a W3C recommendation, adopted May 10, 2011. Whereas VoiceXML is designed to provide a Voice User Interface to a voice browser, CCXML is designed to inform the voice browser how to handle the telephony control of the voice channel. The two XML applications are wholly separate and are not required by each other to be implemented - however, they have been designed with interoperability in mind Status and Future CCXML 1.0 has reached the status of a Proposed Recommendation. The transition from Candidate Recommendation to Proposed Recommendation took 1 year, while the transition from Last Call Working Draft to Candidate Recommendation took just over 3 years. As CCXML uses extensively the concepts of events and transitions, it is expected that the state machines used in the next CCXML 2.0 version will take advantage of a new XML State Machine notation called SCXML, however SCXML is still in Working Draft. Implementations OptimTalk is an application platform providing a wide range of technologies and tools for managing, processing and automation of voice communication. It contains a media server supporting VoiceXML 2.0/2.1, CCXML, MRCPv2 and SIP. Besides these open standards it further supports SRGS, SISR, SSML, HTTP(S), SOAP, REST and SNMP. OptimTalk also serves as a versatile platform for computer telephony integration (CTI) and provides an instant access to speech technologies. It is available for Windows, Linux and Solaris, 32 and 64 bit. Oktopous ccXML Browser is a first Linux based comprehensive ccXML "light weight" tool kit, that conforms to the Working Draft spec of CCXML 1.0 published in April 2010. Oktopous enables developers to take advantage of well-known Web technologies and tools when building their telephony and speech applications. The Oktopous Engine powers over 5 million calls daily, and is free to download and integrate before going live.
