If your interest is in keeping costs down, you might want to build an open source stack to support your application:
* VoiceXML Interpreter: Open VXI (http://sourceforge.net/projects/openvxi/)
* CCXML Interpreter: Oktopous (http://sourceforge.net/projects/oktopous/)
* TTS Engine: Festival (http://fife.speech.cs.cmu.edu/festival/)
* ASR Engine: Sphinx (http://cmusphinx.sourceforge.net/)
* JavaScript Engine: SpiderMonkey (http://www.mozilla.org/js/spidermonkey/)
It looks like the Open VXI component will run on multiple platforms, but for most everything else, your going to run it on a Linux distribution. (Note � some of the components listed above might still be in beta release.)
Your also going to need a telephony board in whatever machines are housing the environment to connect to the PSTN. You'll probably use either a Brooktrout or Dialogic board. Doing a quick check, it looks like most of the turnkey VoiceXML solution use either the Dialogic J-Series boards or the Brooktrout TR1000 board (http://www.brooktrout.com/products/tr1000/). Not sure which runs better under Linux, but there may be some info. on the web.
Hope this is helpful.
