How to Install OpenSIPS Server on Ubuntu 15.04

OpenSIPS is an open source SIP Proxy program that runs on Linux platforms and play in the infrastructure of an Internet Telephony Service Provider. There are number of open source applications available that are used to build IP Telephony solutions. OpenSIPS may not be as well-known as Asterisk, but it is widely used by VOIP service providers as a core part of their infrastructure because of its robustness, speed and capacity.

In this article we will take you through the steps needed for downloading OpenSIPS sources and then compiling and installing it on the Ubuntu 15 server. So at the end of this article you'll see a working openSIPS server and able to see that how it will generate a working configuration file based on your desired functionalities.


OpenSIPS server installation requires some basic modules to be installed on the Ubuntu server that can be installed using the simple 'apt-get' command. Once your back end server is ready to deploy the OpenSIPS then login using the sudo or root user to perform the following tasks.

1) System Update

Once you are connected to your CentOS 7 server, run the following command as a root user to update your system with latest updates and security patches.

# apt-get update
system update

2) Installing Dependencies:

After system update you need to install the missing packages using the 'apt-get' command if these are not already installed.

# apt-get install build-essential openssl bison flex

To continue the installation you will be asked to type 'y' key. This will install all required missing packages including their dependencies as shown .

OpenSips Dependencies

Still few more dependencies left that need to be installed, to do so run the following command.

# apt-get install perl libdbi-perl libdbd-mysql-perl libdbd-pg-perl libfrontier-rpc-perl libterm-readline-gnu-perl libberkeleydb-perl ncurses-dev
Opesips dependencies

3) Installing MySQL Server:

In order setup database for the OpenSIPS server we need a Database server. So, we are going to use MySQL-Server by using the community repository. Let's run the following commands to install MySQL server and it development libraries.

# apt-get install mysql-server libmysqlclient-dev
Installing Mysql

Now you will be able to install the MySQL local server and MySQL headers by press the 'y' key. During its setup you will be asked to configure the root password for MySQL server, so type your secure password and press 'OK' to proceed.

set mysql password

4) Download OpenSIPS Package:

Open the Official OpenSIPS Source Page to download the package.

OpenSIPS Source

We are going to download the package into the following directory using 'wget' command and the extract within th esame directory.

# cd /usr/src
# wget
# tar -zxvf opensips-2.1.2.tar.gz
download opensips

5) Compiling OpenSIPS Source:

Moving step ahead let's move into the opensips directory and run the command below to start the compilation process.

# cd opensips-2.1.2/
# make all
Compiling Opensips

6) Installing OpenSIPS Source:

Once the compilation process completes, you can start making its installation as shown below.

# make install
make install

7) OpenSIPS Configuration:

The OpenSIPS has been installed, now we are going to configure some of its basic parameters and startup script. Let's first create a new directory for the OpenSIPS run files.

# mkdir /var/run/opensips

Now move to the following 'debians' directory and list the files in it.

# cd packaging/debian/
Debian Files

Here you see the opensips default and init files that we will copying to the '/etc/default/' directory using the following commands.

# cp opensips.default /etc/default/opensips
# cp opensips.init /etc/init.d/opensips

Then run the following commands to give executable permissions to the opensips startup script, create and new user and then update its default boot configurations as shown below.

# chmod +x /etc/init.d/opensips
# useradd opensips
# update-rc.d opensips defaults 99
Opensips settings

Open the default file of Opensips using any of your editor to configure its startup options.

# vim /etc/default/opensips

Here you need to replace the 'RUN_OpenSIPS' to 'Yes'. You can also change the user and group and name that you wish to use for the Opensips services and also change the shared memory to minimum 128 which is recommended for the OpenSIPS server.

Opensips Statup

we also need to update the daemon on OpenSIP and change it location in its startup script and update its state from 'off' to 'on' and then close the file after making changes as shown in the below image.

# vim /etc/init.d/opensips
opensips daemon

Starting OpenSIPS Service:

All necessary configurations has been setup to proceed on starting OpenSIPS service. Simply run the following command to start OpenSIPS and the check its status, that should be active and running as shown in the image.

# /etc/init.d/opensips start
# systemctl status opensips
start opensips

You can also check the state of OpenSIPS services and the port on which its running that is '5060' by using the below commands.

# ps -ef | grep opensips
# netstat -alnp | grep opensips
opensips processes

  1. I tried to install opensips in ubuntu 14.04. Everything worked fine till I entered the command "# systemctl status opensips" in terminal. It showed that systemctl command isn't found. I know systemctl works on 15.04 and above. Should I use some other command in place of that or leave that command if it isn't necessary.

    Also I wasn't getting anything in terminal when I typed last two commands
    # ps -ef | grep opensips
    # netstat -alnp | grep opensips

  2. Nice article, only i faced problem to start opensips server.
    I did following change and it worked fine:

    1. nano /etc/init.d/opensips
    Open this file and change CFGFILE path as below and start opensips server
