UC500.com Cisco CallManager Express, UC500 reference

Berbee has some example XML services that are free to use at http://www.berbee.com/public/berbeesoftware/XMLFree.aspx
The problem is that one cannot simply add a service to the url services: a new service always replaces the current service. That why you have to create a custom menu.xml file on your webserver if you still want to use VoiceView Express. (The instructions on Berbee's site are for full blown Call Manager.)

Here's an example menu that I use in demo's for the UC520

Has anyone successfully setup a Berbee free XML with Call Manager Express?

I am interested in developing applications that communicate and integrate with the UC 500 system for SMBs. Can anyone tell me what is required to do this or is it possible?
