The (AGI) Asterisk Gateway Interface is an interface for adding functionality to Asterisk with many different programming languages. Perl, PHP, C, Pascal, Bourne Shell, or any other programming language that you like.
To use AGI, create an extension on extension.conf, with this format (example extension number 5151):
exten => 5151,1,AGI(test.php)
Then place the script (for example in PHP, test.php) on the specified AGI folder in asterisk.conf, for example in /var/lib/asterisk/agi-bin.
The script should be executable, so you must first chmod +x to the script.
As an example, let create simple AGI application that fetch the web for a currency data and speak it to the caller. To simplify our self, we are going to use PHP and PHPAGI library.

Well I’m sorry, it’s been so long for this part to come.. I had been working very hard on some clients and don’t have enough time to write. Here’s what I had been done if you’re curious 
: http://maps.GpsTrackingIndonesia.com, www.SunberryCorp.com, www.mypushme.com, www.kulacak.com, www.web2trace.com, www.pushmeportal.com, … The fun is almost all of them was written with CodeIgniter .
Ok, let’s start with the easiest one first. We will create a simple menu page that contains links to other modules on the system. We put it on the Mainpage controller class.
Look at the Mainpage.php controller file. There is a function on it named exactly the same with the filename: Mainpage(). This should be exactly the same including the case. This is the constructor or initialization function of the class. Each time the class is called or instantiate, this function is called automatically. We put some initialization lines inside it:

The command we need to use to list the packages currently installed in Ubuntu or Debian is dpkg –get-selections. For example:
# dpkg --get-selections
acpi install
acpi-support-base install
acpid install
adduser install
apache2 install
apache2-mpm-prefork install
apache2-utils install
apache2.2-common install
apt install
apt-utils install
aptitude install
autoconf install
automake install
automake1.4 install
autotools-dev install
avahi-daemon install
bacula-common install
bacula-fd install
base-files install
base-passwd install
bash install
bind9-host install
binutils install
…
It will return a long list showing all the installed packages. To filter to specific list of packages, for example we only need to show java packages, combine it with grep, for example:
# dpkg --get-selections|grep java
java-common install
java-gcj-compat install
java-gcj-compat-headless install
libbcel-java install
liblog4j1.2-java install
liblog4j1.2-java-gcj install
libmx4j-java install
libpg-java install
libregexp-java install
sun-java6-bin install
sun-java6-jdk install
sun-java6-jre install
We can find the locations of the files within a package from the list by using the dpkg -L command, such as:
# dpkg -L sun-java6-jdk|more
