Kamailio is an open source SIP server which provides excellence performance, scalability and security. In this tutorial, you will learn how to install Kamailio on Arch Linux.
Before we begin, make sure that you have the following:
First of all, we need to update our package manager.
To update Arch Linux, run the following command:
sudo pacman -Syu
The -S flag is for installing, the -y flag is to assume yes as an answer to all questions, and the -u flag is to upgrade the system.
To install Kamailio on Arch Linux, we need to run the following command:
sudo pacman -S kamailio
This will download and install the Kamailio package on your system.
Kamailio's configuration file is located in /etc/kamailio/kamailio.cfg. We need to edit this file to configure Kamailio.
sudo nano /etc/kamailio/kamailio.cfg
Here are some parameters which you can configure as per your requirements:
$Listen : Kamailio listens to SIP traffic on this IP address.$Port : The port on which Kamailio listens to SIP traffic.$Modparams : The various modules of Kamailio.$DynamicRoutes : The routing logic used by Kamailio.You can add or modify these parameters based on your needs.
To start Kamailio, run the following command:
systemctl start kamailio
To check the status of Kamailio, run the following command:
systemctl status kamailio
If everything is fine, you should see something like this:
kamailio.service - Kamailio (OpenSER) - the Open Source SIP Server
Loaded: loaded (/usr/lib/systemd/system/kamailio.service; disabled; vendor preset: disabled)
Active: active (running) since Mon 2021-08-02 09:47:23 UTC; 4min 30s ago
Main PID: 17209 (kamailio)
Tasks: 23 (limit: 4915)
Memory: 38.7M
CGroup: /system.slice/kamailio.service
├─17209 /usr/sbin/kamailio -P /run/kamailio/kamailio.pid -f /etc/kamailio/kamailio.cfg
└─17217 /usr/sbin/kamailio -P /run/kamailio/kamailio.pid -f /etc/kamailio/kamailio.cfg
To test Kamailio, we can use the command sipp.
First, install sipp by running:
sudo pacman -S sipp
Then, execute the following command to create a new call using Kamailio:
sipp -sn uac 127.0.0.1:5060 -m 1
If everything works fine, you should see something like this:
