Let’s start installing it on the server now.
Login to your server as root.
I am using asterisk 1.4 (I have done this on 64 bit server – make sure to download the right tarball) – you can download asterisk by the command:
root# wget http://downloads.digium.com/pub/asterisk/releases/asterisk-1.4.23.tar.gz
Now, we will start the installation process. If you get any errors of dependencies you will have to install it. I have installed it using yum ( few were ncurses, gcc, gcc-c++, zaptel, subversion) – install ncurses before the installation starts this will make “make menuconfig” command work perfect.
root# tar zxvf asterisk-1.4.23.tar.gz
root# cd asterisk-1.4.23
root#./configure
root# make menuconfig -- hit 'x' to save and exit with default setting
root# make
root# make install
root# make samples
root# asterisk
Now, open the ports in the firewall by the commands:
root# iptables -I INPUT -p tcp --dport 8088 -j ACCEPT
root# iptables -I INPUT -p udp --dport 8088 -j ACCEPT
root# service iptables save
root# service iptables restart
root# iptables -I INPUT -p tcp --dport 5308 -j ACCEPT
root# iptables -I INPUT -p udp --dport 5308 -j ACCEPT
root# service iptables save
root# service iptables restart
Asterisk is installed, now proceeding to installation of Asterisk-GUI
svn checkout http://svn.digium.com/svn/asterisk-gui/branches/2.0/ asterisk-gui
cd asterisk-gui/
./configure
make
make install
Edit /etc/asterisk/http.conf with your favourite editor and change the following lines:
enabled=yes
enablestatic=yes
bindaddr=123.123.123.123
Where 123.123.123.123 is your server IP.
This enables the HTTP server, enables it to serve static content (the GUI itself) and binds to the standard address, so that any browser from a remote machine can access it.
Now, configuring the manager access
Edit /etc/asterisk/manager.conf and change the following lines:
enabled = yes
webenabled = yes
Then add a new section at the end of the file
[admin]
secret = supportfacility
read = system,call,log,verbose,command,agent,user,config
write = system,call,log,verbose,command,agent,user,config
This will allow a user called admin to connect with the password supportfacility and do nearly everything on the system.
Now restart Asterisk by the command:
root# asterisk
Do one last check with the command
make checkconfig
If everything goes well, and you get a “Good Luck” connect with your browser to:
http://Server-IP:8088/asterisk/static/config/cfgbasic.html
Username: admin
Password: supportfacility
This will take sometime and then you will get the below URL.
http://Server-IP:8088/asterisk/static/config/index.html
Start configuring your Asterisk now.
Best of luck!
