Before you begin, you’ll probably want to bring all your packages up to date. To do so, run ‹yum -y update›. If any kernel files were updated as part of this process, you will need to reboot the machine (shutdown -r now). Repeat the process until no more updates are available.
Download the pre-requisite of asterisk:
gcc
gcc-c++
kernel-devel
bison
openssl-devel
libtermcap-devel
libxml2-devel
We’ll be using yum for now(there’s no support for apt-get in CentOS 5)
yum -y update
yum install gcc gcc-c++ kernel-devel bison openssl-devel libtermcap-devel libxml2-devel
yum install festival
then download the latest asterisk version at asterisk.org to /usr/src:
cd /usr/src
wget http://downloads.digium.com/pub/asterisk/asterisk-1.4-current.tar.gz
wget http://downloads.digium.com/pub/zaptel/zaptel-1.4-current.tar.gz
#if you plan to use PRI cards(eg. TE110P, TE406P) you need to download this package:
wget http://downloads.digium.com/pub/libpri/libpri-1.4-current.tar.gz
then untar all the files
tar -zxf zaptel-1.4-current.tar.gz
tar -zxf asterisk-1.4-current.tar.gz
tar -zxf libpri-1.4-current.tar.gz
