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 Proposed 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
