I think no one will help you because you don`t know what you want to do.
Please specify your question.

Have you read Asterisk: The Future of Telephony, and looked at the Wiki on voip-info.org?

If those don’t help, you need to attend a professionally run course or buy in consultancy. There is another forum, on this server, for the latter.
