Call Control eXtensible Markup Language
Encyclopedia
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

Event (computing)
In computing an event is an action that is usually initiated outside the scope of a program and that is handled by a piece of code inside the program. Typically events are handled synchronous with the program flow, that is, the program has one or more dedicated places where events are handled...

Implementations
- 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.

/PSTN and other telecoms protocols. Supports multi-tenant applications. - Open Source Oktopous PIK an abstract, C++ implementation of the W3C Call Control XML (ccXML) standard. Licensed under a BSD-Style license, the toolkit is independent of the underlying telephony platform / protocols and is best suited for OEM / System Integrators looking to implement ccXML functionality in their product offerings. Originally developed by Phonologies, Oktopous has been adopted by more telephony platforms than any open source ccXML Browser.
- CCXML4J a CCXML Interpreter in Java according to the W3C specification. It is independent of the telephony infrastructure and provides mechanisms to integrate with telephony APIs, e.g. based on the JAIN specifications. This is a derivative of Open Source Oktopous PIK.
- ADVOSS SDP AdvOSS offers the Programmable, Extensible and Enhanceable Service Delivery Platform to enable developers to build and deploy feature rich SIP applications using the industry standard Call Control XML (CCXML), for rapid development and deployment of new services. AdvOSS SDP is a Programmable Extensible and Enhanceable platform that uses industry standard CCXML. For AdvOSS, making the platform programmable and enhanceable made much sense as the whole idea behind using a SDP is to attain the advantage of developing and integrating new services into the system at a brisk pace. Therefore we believe that our customer should have the capacity to program, extend and enhance the different modules of this application to meet the rapidly growing requirements of their customers. The service delivery platform has been built from ground up to enable developers to build and deploy feature rich SIP applications using Call Control XML (CCXML). CCXML provides simple primitives, allowing users to write applications enabling them to quickly transform ideas to solutions. In addition, the AdvOSS platform extends CCXML to support primitives for Authentication, Authorization and Accounting (AAA) allowing applications to interface with billing systems either directly or through RADIUS.
