Asterisk 1.2 auto install script for CentOS 4 and CentOS 5

I created an auto install script to install Asterisk 1.2 for CentOS 4 and CentOS 5. This script will install the following:

  • Zaptel
  • Libpri
  • Asterisk
  • Asterisk Addons
  • Open Source G729 Codec

Before running these script, you must install the some software needed to compile Asterisk.
For CentOS 4:

yum install gcc kernel kernel-devel bison openssl-devel

For CentOS 5:

yum install gcc kernel kernel-devel bison openssl-devel libtermcap-devel ncurses-devel

kernel-smp-devel (instead of kernel-devel) is necessary if you are using a dual core processor.

Asterisk PBX

Asterisk

Having a fully functional PBX system is not a big problem anymore. Thanks to Asterisk, you can now have a working PBX installed on your PC running GNU/Linux without spending a lot of money.

What is Asterisk?

Asterisk is an open source Private Branch Exchange (PBX) that runs on Linux, BSD and Mac OSX. It was created by Mark Spencer of Digium in 1991. Like any PBX, it allows a number of attached telephones (extensions) to make calls to one another, and to connect to other telephone services including the public switched telephone network (PSTN).

The basic Asterisk software provides all of the features you would expect from a proprietary PBX including: voicemail, conference calling, interactive voice response (IVR), and automatic call distribution (queue). These are just a few of the features that it can provide, you can view a list of supported features at Asterisk's Web site.
