Asterisk Install

Prerequisite

Make sure all your compilers are installed.

yum -y install make gcc gcc-c++ ncurses-devel libtermcap-devel kernel-devel kernel-smp-devel openssl-devel newt-devel zlib-devel

Installing Asterisk 1.6.x

If you are wanting a nice simple way to install asterisk, have a look at Aster-install. The following is based on CentOS 5.2 as been installed with the minimal components including the development tools.

The First thing I did was to download the Asterisk source files.

Asterisk 1.6.0.9
DAHDI Linux 2.1.0.4
DAHDI Tools 2.1.0.2
Addons 1.6.0

I did not download and install the Libpri package as I don't have any primary rate cards installed on my system.

NOTE: If you would like to download, install and use the latest and greatest version of Asterisk (the cutting edge) download the files listed on the Asterisk SVN Install page. If you do download the SVN files don't download the files listed below.

mkdir /usr/src/asterisk
cd /usr/src/asterisk
wget http://downloads.digium.com/pub/asterisk/releases/asterisk-1.6.0.9.tar.gz
wget http://downloads.digium.com/pub/asterisk/releases/asterisk-addons-1.6.0.tar.gz
wget http://downloads.digium.com/pub/telephony/dahdi-linux/releases/dahdi-linux-2.1.0.4.tar.gz
wget http://downloads.digium.com/pub/telephony/dahdi-tools/dahdi-tools-2.1.0.2.tar.gz
wget http://downloads.digium.com/pub/libpri/releases/libpri-1.4.7.tar.gz

dahdi-linux

DAHDI (stands for Digium Asterisk Hardware Device Interface) is the replacement for Zaptel. As I have an X100P card installed into my system I need to install the Linux driver. If you do not have any telecommunications cards installed you will still need to do the following so that ztdummy is installed. This is the timing device so that MOH can be played.

tar xvzf dahdi-linux-2.1.0.4.tar.gz
cd dahdi-linux-2.1.0.4
make
make install

dahdi-tools

tar xvzf dahdi-tools-2.1.0.2.tar.gz
cd dahdi-tools-2.1.0.2

./configure
make menuselect
make
make install
make config

Once the above is done we need to edit /etc/dahdi/modules and make sure that only the required dahdi module(s) is/are loaded. If you only want ztdummy install you need to remark out all the other drivers.

faxing prerequisites

If you would like to be able to use faxing capabilities with Asteirsk you need to install a few packages so that Asterisk can build the faxing components.

First of all edit the file and add the following line:
/etc/ld.so.conf

/usr/local/lib/

yum install libtiff-devel

cd /usr/src
wget http://www.soft-switch.org/downloads/spandsp/spandsp-0.0.6pre7.tgz
zcat spandsp-0.0.6pre7.tgz | tar xf -
cd spandsp-0.0.6
./configure
make
make install
ldconfig

installation

cd /usr/src/asterisk
tar xvzf asterisk-1.6.0.9.tar.gz
cd asterisk-1.6.0.9
./configure
make menuselect
make
make install
make samples
make config

asterisk-addons

When you have finished the process on this page make sure you have a look at how to record your CDR to MySQL.

prerequisite

One of the main features of the asterisk-addons is the ability to log CDR to mysql. I found that mysql is required to be started for the addons to recognise the requirement of mysqlclienttools.

If you are not interested in logging CDR to mysql then this step is not required.

yum install mysql-server mysql-devel
service mysqld start
chkconfig mysqld on

installation

tar xvzf asterisk-addons-1.6.0.tar.gz
cd asterisk-addons-1.6.0

./configure
make menuselect
make
make install
make samples
