How to Install OpenSIPS on Elementary OS

OpenSIPS is an open-source SIP server that can be used for voice, video, and messaging services. In this tutorial, we will show you how to install OpenSIPS on the latest version of Elementary OS.

Prerequisites

Before we start, make sure your system meets the following requirements:

You have root access to your Elementary OS system.
You have a stable and fast internet connection.

Step 1: Update the System

The first thing you should do is to update your system using the package manager apt. You can do that by running the following command in the terminal:

sudo apt update && sudo apt upgrade -y

Step 2: Install Dependencies

OpenSIPS requires some dependencies that need to be installed before the main package can be installed. These dependencies include:

SQLite
libpcre3-dev
libssl-dev
libxml2-dev
bison
flex

You can install these dependencies by running the following command:

sudo apt install sqlite3 libsqlite3-dev libpcre3-dev libssl-dev libxml2-dev bison flex -y

Step 3: Download and Install OpenSIPS

Go to the OpenSIPS download page and download the latest stable version of the software.
Extract the downloaded archive:
```
tar zxvf opensips-VERSION.tar.gz
```
Replace VERSION with the version number of OpenSIPS that you downloaded.
Enter the extracted directory:
```
cd opensips-VERSION
```
Replace VERSION with the version number of OpenSIPS that you downloaded.
Configure the installation:
```
make menuconfig
```
This command will launch a configuration menu that allows you to select the modules that you want to include in your OpenSIPS installation. Use the arrow keys to navigate the menu and the spacebar to select/unselect modules.
Compile the source:
```
make all
```
Install the binaries:
```
sudo make install
```

Step 4: Verify the Installation

To verify that OpenSIPS has been installed correctly, you can check its version:
```
opensips --version
```
You can also run OpenSIPS in debug mode and check its logs:
```
opensips -dddd
```
This command will launch OpenSIPS in debug mode with the highest log level. You can exit debug mode by pressing Ctrl+C.

Congratulations! You have successfully installed OpenSIPS on your Elementary OS system. You can now start using it to provide SIP services. If you encounter any issues or errors during the installation process, refer to the OpenSIPS documentation for more information.
