Follow these instructions for the Easiest, Totally Automated FreePBX install.
1. Download the ISO file from http://schmoozecom.com/distro-download.php.
2. Convert the ISO file to a DVD or CD. On Windows 7 machines, right click on the file and select "open with," and then Windows Disc Image Burner. For computers running other operating systems, Google convert ISO to CD and you'll find plenty of instructions.
3. Select a computer to install the FreePBX Distro on. EVERYTHING ON THIS COMPUTER WILL BE DELETED AND REPLACED WITH THE FREEPBX DISTRO. Configure the computer to boot from a DVD or CD. Insert the DVD or CD into the computer and turn it on.
NOTE: You must be connected to the internet to run the installer
If you're installing using a USB drive, you may encounter a "kickstart" error while installing. If you do, don't fret! Just keep hitting enter when the prompts appear and everything will probably work just fine.
4. The installer will begin with a prompt to select the Asterisk Version you wish to install.
5. The system will present you with a window showing that it is retrieving images while it downloads the install package from the internet. That should take 3-5 minutes.
6. After the system boots you will see options to configure your network. The default selections are fine in most cases, so just press TAB until the red "OK" box is highlighted in white and then press ENTER. You can also choose the option to manually configure your network connections if desired.
Once you hit “OK” the system will configure your Network Connections.
7. Eventually, you will reach the "Time Zone Selection" screen. If your system clock uses GMT (most do not), hit space. Then, hit TAB to move to the time zone selection area. Use the up and down arrows to select the time zone where you will use the system, and then hit TAB until the red "OK" button is highlighted in white. Then, hit ENTER.
8. The installer will ask you to to select your Root password. The Root password is the password you'll use to login to the Linux command prompt later. Selecting a secure password is very important. Type the password, hit TAB, type it again, hit TAB, and then hit ENTER.
9. The installer will do a dependency check, will format your hard drive, and then start the package installation process. There may be a significant delay before the installation actually starts, so be patient. Eventually, the installation will show you a progress bar indicating the percentage completed and the time elapsed/remaining. That process should take between 20 and 30 minutes, it will then reboot.
10. The installer will install the bootloader and some other scripts, and then reboot your computer again. More white text will appear on a black background as the completed installation boots. A few additional packages will be installed and updated while in this mode. Your computer will then reboot again.
11. Once installed your computer will boot, and you'll reach the Linux console/command prompt login. You can login here using the username "root" without quotes, and the Root password you selected earlier.
12. After you login, type "ifconfig" at the command line to determine the IP address of your machine (to the right of eth0).
13. Go to another computer on the same network and enter that IP address into your web browser. The first time you do so you'll be asked to create the admin user and the admin password. That username and password will be used in the future to access the FreePBX configuration screen. Note: These passwords do not change the Root password! They are only used for access to the FreepBX web interface.
14. The main FreePBX screen will offer you four options:
PBX Administrator will allow you to configure your PBX. Use the admin user and admin password you configured in the step above to login. This section is what most people refer to as "FreePBX."
The User Control Panel
The Operator Panel is a screen that allows an operator to control calls
