CCXML scripting engine
The CCXML scripting engine enables the CX Video Gateway to execute applications
written in the W3C Working Draft of CCXML dated 29th June 2005
(http://www.w3.org/TR/2005/WD-ccxml-20050629). You can use CCXML to write
applications that provide call control for the duration of a phone call, including call
setup, monitoring, and tear-down. You can also use CCXML applications to provide
call routing and conferencing functionality.
