Configuration steps

Before you start to configure this solution, it is assumed that you have already installed your linux distribution and downloaded Ozeki Phone System from the download page.

Step 1.) Install Kamailio PBX

Connect your 3rd party PBX with Ozeki Phone System. The computer where you install PBX will be a virtual machine or a computer. Start with a simple installation to co-operate with Ozeki Phone System. Follow the installation guide at Kamilio wizard. There are some packages that need to install for kamilio installation.

Use the following command to install the packeges. After the install command type the packeges names(git client,gcc compiler,flex,bison,libmysqlclient-dev,make)

sudo apt -get install

Before you start configure SIP account install 3rd party PBX,which needs the following packages.

When the inicializing finished and installed packages, create a directory where the sources will be stored. Then download the sources from GIT:

git clone --depth 1 --no-single-branch git:// kamailio

Type simple cd command to jump to kamilio directory and press "git git checkout -b 4.0 origin/4.0" into the command line. After it, install the whole kamilio package in one directory:

make PREFIX="/usr/local/kamailio-4.0" include_modules="db_mysql" cfg

Next installation step to compile the Kamilio. Use "make install" for compiling

To be able to use the binaries from command line, open "/root/.bash_profile" and at the ebd add:

export PATH

Create the database which need for Kamilio:

nano -w /usr/local/etc/kamailio/kamctlrc
/usr/local/sbin/kamdbctl create

To fit your requirements for the VoIP platform, edit the configuration file /usr/local/etc/kamailio/kamailio.cfg Follow the instruction in the comments to enable usage of MySQL.

You should modify init.d file. Browse the directory with cd command and use the following commands:

chmod 755 /etc/init.d/kamailio

After that edit the following $DAEMON and $CFGFILE values:

mkdir -p /var/run/kamailio

Finally you should start the service which you have install. If you want to add a user just use the "adduser" command. To start/stop the server:

/etc/init.d/kamailio start
/etc/init.d/kamailio stop

Finally you will and your new account for logging:

kamctl add username password email

If you finished installation you can start with SIP account configuration.

Step 2.) Create a SIP account

First, login to your linux distribution, start a terminal and type su to login as administrator (Figure 2).

Next, download the Kamailio installation package. Since I use a Fedora distribution in this example, I will need the .rpm package. Download the package with wget in the following way (Figure 3):


download kamailio package

When the package is downloaded, you need to install it. Please note that you will have to skip the gpg check for this package (Figure 4).

yum install kamailio-3.1.3-4.1.i686.rpm --nogpgcheck

install kamailio package

Once Kamailio is installed, you can start using it with its default settings. By default, you don't need to define any extension in Kamailio, and you can register to it with any username or password. All you need to do is to start the Kamailio service in your distribution (Figure 5).
