This guide will help you install the latest Kamailio SIP server on CentOS 7 / CentOS 8 Linux server. This is part of a series of tutorials on building an enterprise VOIP system. Kamailio is a SER distribution that provides a scalable SIP server, suitable for installations from small to carrier grade.
Kamailio features
The main advantages of using Kamailio with media servers such as Asterisk are:
- Kamailio can handle more than 5000 call settings per second.
- Only 4GB of Ram system can serve 300,000 active users.
- Clustering can be easily achieved by adding more Kamailio servers
Kamailio can be used as: ● Registration server ● Location server ● Proxy server ● SIP application server ● Redirect server
Other Kamailio features include:
- Supports NAT traversal of SIP and RTP traffic
- Load balancing with many distribution algorithms and failover support
- Provide flexible and lowest cost routing
- Easy to implement routing failover
- Support both IPv4 and IPv6
- SCTP multi-homing and multi-stream
- Can communicate via UDP, TCP, TLS and SCTP
- Summary SIP user authentication
- Provide event-based accounting
- Data can be stored to database, radius or diameter
- Extensible Java, Python, Lua and Perl programming interfaces
- TLS supports transparent processing of SIP signaling and SRTP to achieve secure audio
We have tested this guide in the following areas:
- Kamailio 5.x
- CentOS 7 / CentOS 8
Install Kamailio SIP server on CentOS 7 / CentOS 8
Before introducing the installation process in depth, let us first understand the basics of Kamailio SIP Server.
Step 1: Set SELinux to allow / disable mode
If you are not a SELinux enthusiast, it is recommended that you put it in “allow” mode:
sudo setenforce 0
sudo sed -i 's/^SELINUX=.*/SELINUX=permissive/g' /etc/selinux/configIf you decide to disable it permanently, you need to restart the CentOS system:
sudo setenforce 0
sudo sed -i 's/^SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config
sudo rebootAfter rebooting, confirm the SELinux status:
$ sestatus SELinux status: enabled SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: targeted Current mode: permissive Mode from config file: enforcing Policy MLS status: enabled Policy deny_unknown status: allowed Max kernel policy version: 31
Step 2: Install MariaDB database server
Kamailio requires a database server to run. For this, we will use the MariaDB database server that can be installed on CentOS 7 / CentOS 8:
sudo yum -y install mariadb-server
sudo systemctl enable --now mariadb
sudo mysql_secure_installationStep 3: Add Kamailio RPM repository
CentOS 8:
sudo wget -O /etc/yum.repos.d/kamailio.repo http://download.opensuse.org/repositories/home:/kamailio:/v5.3.x-rpms/CentOS_8/home:kamailio:v5.3.x-rpms.repoAt the time of this update, some packages are not in the CentOS 8 repository. I have to use Fedora 29 repository on CentOS 8. If you encounter the same problem, please change the repository by running the following command.
sudo wget -O /etc/yum.repos.d/kamailio.repo http://download.opensuse.org/repositories/home:/kamailio:/v5.3.x-rpms/Fedora_29/home:kamailio:v5.3.x-rpms.repo
CentOS 7:
sudo wget -O /etc/yum.repos.d/kamailio.repo http://download.opensuse.org/repositories/home:/kamailio:/v5.3.x-rpms/CentOS_7/home:kamailio:v5.3.x-rpms.repoStep 4: Install Kamailio SIP server on CentOS 8 / CentOS 7
After adding the repository, install the Kamailio SIP server on CentOS 8 / CentOS 7 Linux.
sudo yum install vim kamailio kamailio-presence kamailio-ldap kamailio-mysql kamailio-debuginfo kamailio-xmpp kamailio-unixodbc kamailio-utils kamailio-tls kamailio-outbound kamailio-gzcompressThe dependency tree should be displayed, you can click ÿ Enter the letters on the keyboard to start the installation.

compiled on 14:32:52 Mar 16 2020 with gcc 8.2.1Step 5: Configure Kamailio on CentOS 8 / CentOS 7
Edit file /etc/kamailio/kamctlrc And make sure to set the DBENGINE variable to MySQL. Delete the pound sign to uncomment.
sudo vi /etc/kamailio/kamctlrcSet the database engine to MYSQL
DBENGINE=MYSQL DBHOST=localhost
Run the following command to create the users and tables required by Kamailio (schema).
$ sudo kamdbctl create MySQL password for root: INFO: test server charset INFO: creating database kamailio … INFO: granting privileges to database kamailio … INFO: creating standard tables into kamailio … INFO: Core Kamailio tables succesfully created. Install presence related tables? (y/n): y INFO: creating presence tables into kamailio … INFO: Presence tables succesfully created. Install tables for imc cpl siptrace domainpolicy carrierroute drouting userblacklist htable purple uac pipelimit mtree sca mohqueue rtpproxy rtpengine secfilter? (y/n): y INFO: creating extra tables into kamailio … INFO: Extra tables succesfully created. Install tables for uid_auth_db uid_avp_db uid_domain uid_gflags uid_uri_db? (y/n): y INFO: creating uid tables into kamailio … INFO: UID tables succesfully created.
When asked for the root password, enter the MySQL root user password that was configured mysql_secure_installation
Answer “yes” to all subsequent questions. of kamdbctl create This command will add two Mysql users:
Camellio: With password.kamailiorw It has read / write access to Kamailio database.
Camellio: The user’s password is kamailioro. It has read-only access to the Kamailio database.
Next is editing /etc/kamailio/kamailio.cfg Configure Kamailio:
sudo vi /etc/kamailio/kamailio.cfgAdd the following line below #! KAMAILIO.
#!define WITH_MYSQL
#!define WITH_AUTH
#!define WITH_USRLOCDB
#!define WITH_NAT
#!define WITH_PRESENCE
#!define WITH_ACCDB
Start Kamailio
sudo systemctl restart kamailioEnable the service to start at startup:
sudo systemctl enable kamailioSo far. Now, you should have a running Kamailio SIP server on CentOS 8 / CentOS 7 Linux.
$ systemctl status kamailio
