I am trying to install Asterisk & FreePBX by following this tutorial: on the website asteriskonvpsDotCom.
Even though I get an error when I insert the command: amportal chown /etc/dahdi/modules that the directory / file does not exist.
Then I have successfully installed AsteriskNow on my VPS with Centos 6.0 and Plesk 12.
I read somewhere else that I should access the FreePBX GUI by visiting it IP address of the server, even though when I visit this address I see the Plesk default page.
