Voice Browser Call Control: CCXML Version 1.0

This document describes CCXML, or the Call Control eXtensible Markup Language. CCXML is designed to provide telephony call control support for dialog systems, such as VoiceXML [VOICEXML]. While CCXML can be used with any dialog systems capable of handling media, CCXML has been designed to complement and integrate with a VoiceXML interpreter. Because of this there are many references to VoiceXML's capabilities and limitations. There are also details on how VoiceXML and CCXML can be integrated. However, it should be noted that the two languages are separate and are not REQUIRED in an implementation of either language. For example, CCXML could be integrated with a more traditional Interactive Voice Response (IVR) system or a 3GPP Media Resource Function (MRF), and VoiceXML or other dialog systems could be integrated with other call control systems.

This document describes CCXML, the Call Control eXtensible Markup Language. CCXML provides declarative markup to describe telephony call control. CCXML is a language that can be used with a dialog system such as VoiceXML [VOICEXML].

CCXML can provide a complete telephony service application, comprised of Web server CGI compliant application logic, one or more CCXML documents to declare and perform call control actions, and to control one or more dialog applications that perform user media interactions
