IVR + Dialogic

Friends,
I am currently working on an IVR(interactive voice response) project using Dialogic, where i am using Intel's VOS for coding the call flows. But i want to code it using API calls as i find that gives me a better view of the system, and better handling capabilities. The support in the dialogic CD are in bits in pieces, nothing organised for a starter.

If any one of you can guide with tutorial and starter code, it would be a great help.
