Please let me now what is going wrong.

Have you purchased the G729 license from digium.com

No mate, I am not purchased it from digium.com. I have download it from the Asterisk site and simply install it.

Ok well its a licensed paid codec so you need to purchase the license and activate it from digium.com

You may have noted this at the top of the page:

That is not an Asterisk site, it’s a hacker site in Latvia.

You probably downloaded the wrong version.
