Includes every detail in the form of step by step instructions from bare metal to a running VoIP PBX in about 2 hours.

When installing Linux, do NOT install a GUI such as Gnome or KDE.  We only want to be running in console text mode not GUI graphics mode.  If you already have a desktop or server GUI installed you will want to exit to console mode.  You do that by typing init 3 from a terminal or console window.  You will need to be logged in as root in order to do this so if not you can su root.  All instructions in this guide are assuming you are always logged in as root.

This guide will explain how to replace Flash Operator Panel v1, which is included in FreePBX, with Flash Operator Panel v2 on a RedHat Enterprise Linux server running Asterisk+FreePBX.  It is important to note that FOP1 is completely free whereas FOP2 is free only up to 15 buttons.  Every element is considered a button.  So all extensions + trunks + queues + parking lots + etc. must add up to 15 or less.  After that no more buttons will appear until you buy a license.

A key advantage of FOP2 is that it requires an extension and password to view.  With FOP1 there is no built in way to prevent everyone from viewing the PBX status.

A short guide on how to use High Definition VoIP on Asterisk and FreePBX.

What is it
HD VoIP in the Asterisk world involves selecting the g722 codec for VoIP calls.  g722 is known as a wideband codec as opposed to g711 which is narrowband.  The nice thing about it is that it does not require any more bandwidth than g711.  Both require 64kbit/s each way for a 2-way conversation.
