Giridhar,
You have not provided much information about this project so I’m not sure how anyone will be able to assist. If you can post further information maybe someone can help, although integrating CC processing within asterisk is a fairly involved process.
I have a similar problem ‘I need to call an exe file or a web service in the middle of my call flow. Is there anyone who can help me on that?
I can answer your questions, can you please let me know what you need to know.
