FreePBX with AJAM


I wonder if anyone from community help me out to put AJAM in asterisk.Documents i read about How to install AJAM in asterisk requires http.conf file which should be in /etc/http.conf to make asterisk built in http micro server workable.but the file is not there.

Is this missing as because of FreePBX bundle with asterisk?
Is there any way to to put AJAM on FreePBX running system?

There is a post here describes same issue

but the above post doesn’t have any solution.

It would be great if you guys cud help me in this regard.
