I have updated the project with the classes documentation that you can browse online here. And corrected the licence on Freshmeat, I don’t know how this happen, but the licence of the VoiceXML PHP Framework is GPL and not PHP license. Anyway a copy of the GPL license is distributed with the package.
Documentation are available in HTML, CHM and PDF attached in the download package of the VoiceXML PHP framework. I’ll try to make more tutorials and articles about using this framework, also by introducing other new application as I have promised in the previous posts.
