Kamailio is a powerful and highly scalable Open Source SIP Server that is used to build large scale VoIP platforms. In this tutorial, we will show you how to install Kamailio on Elementary OS Latest.

Prerequisites

Before starting, you will need the following:

A user account on the Elementary OS Latest system with root privileges
Basic knowledge of the Linux command line

Step 1: Enabling the Kamailio Repository

First, you need to enable the Kamailio repository on your system. You can do this by adding the Kamailio apt repository information to your system's sources.list file.

Open the terminal by pressing Ctrl+Alt+T.
Run the following command to edit your sources.list file:
```
sudo nano /etc/apt/sources.list
```

Add the Kamailio repository information at the end of the file:

deb https://deb.kamailio.org/kamailio50 xenial main
deb-src https://deb.kamailio.org/kamailio50 xenial main

Save and close the file by pressing Ctrl+X, then Y, and finally Enter.

Step 2: Installing Kamailio

Once the Kamailio repository is enabled on your system, you can install Kamailio by executing the following commands:

Update the package list:
```
sudo apt update
```
Install Kamailio:
```
sudo apt install kamailio kamailio-tls-modules kamailio-mysql-modules kamailio-utils-modules
```
This command installs Kamailio, the TLS, MySQL, and utils modules. If you don't need any of these modules, you can skip their installation by removing them from the command.
During the installation process, you will be prompted to select a database configuration. Select the mysql option and enter the root password when prompted.
Once the installation is complete, start Kamailio by executing the following command:
```
sudo service kamailio start
```
You can also check the status of Kamailio by executing the following command:
```
sudo service kamailio status
```

Step 3: Testing Kamailio

To test if Kamailio is running properly, you can use the Kamailio-cli tool. The Kamailio-cli tool is a command-line interface for interacting with the Kamailio server.

To access the Kamailio-cli tool, execute the following command:
```
kamctl
```
Once you are in the Kamailio-cli tool, you can use various commands to test the Kamailio server. For example, you can check the version of Kamailio by executing the following command:
```
kamctl version
```

Congratulations! You have successfully installed Kamailio on Elementary OS Latest, and you can now use it to build large scale VoIP platforms.
