Installing Asterisk 1.8.x

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

Asterisk 1.8.7.0
DAHDI Linux and Tools 2.5.0.1

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-1.8.7.0.tar.gz
wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/releases/dahdi-linux-complete-2.5.0.1+2.5.0.1.tar.gz
wget http://downloads.asterisk.org/pub/telephony/libpri/releases/libpri-1.4.12.tar.gz

lipbri

Install lipbri is you are connecting to a PRI service.

tar xvzf libpri-1.4.12.tar.gz
cd libpri-1.4.12
make
make install

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-complete-2.5.0.1+2.5.0.1.tar.gz
cd dahdi-linux-complete-2.5.0.1+2.5.0.1
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.

asterisk

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 add the following line to /etc/ld.so.conf.

echo /usr/local/lib/ >> /etc/ld.so.conf

yum install libtiff-devel

cd /usr/src
wget http://www.soft-switch.org/downloads/spandsp/spandsp-0.0.6pre19.tgz
zcat spandsp-0.0.6pre19.tgz | tar xf -
cd spandsp-0.0.6
./configure
make
make install
ldconfig
