Kamailio: Konfigurasi Awal di OpenWRT

Buat Database MySQL

Edit

cd /etc/kamailio/
nano -w /etc/kamailio/kamctlrc

Ubah

DBENGINE=SQLITE
DB_PATH="/etc/kamailio/sqlite"

Setelah kamctlrc di ubah, jalankan

kamdbctl create kamailio.db

You can call this script without any parameter to get some help for the usage. You will be asked for the domain name Kamailio is going to serve (e.g., mysipserver.com) and the password of the 'root' MySQL user. The script will create a database named 'kamailio' containing the tables required by Kamailio. You can change the default settings in the kamctlrc file mentioned above.

Script ini akan membuat dua user di MySQL:

• kamailio - (dengan default password 'kamailiorw') - user which has full access rights to 'kamailio' database
• kamailioro - (dengan default password 'kamailioro') - user which has read-only access rights to 'kamailio' database

Do change the passwords for these two users to something different that the default values that come with sources.

Edit file konfigurasi

To fit your requirements for the VoIP platform, you have to edit the configuration file.

vi /etc/kamailio/kamailio.cfg

Aktifkan penggunaan MySQL. Paling tidak kita perlu menambahkan dibagian atas config file, seperti:

# use sqlite database                                                        
loadmodule "db_sqlite.so"  

#!ifndef DBURL                                                               
#!define DBURL "sqlite:///etc/kamailio/kamailio.db"                            
#!endif  

If you changed the password for the 'kamailio' user of MySQL, you have to update the value for 'db_url' parameters.

You can browse kamailio.cfg online on GIT repository.

Edit /etc/default

vi  vi /etc/default/kamailio 

Ubah

RUN_KAMAILIO=yes

Script init.d

The init.d script can be used to start/stop the Kamailio server in a nicer way. A sample of init.d script for Kamailio is provided at:

/usr/local/src/kamailio-4.2/kamailio/pkg/kamailio/deb/debian/kamailio.init

Just copy the init file into the /etc/init.d/kamailio. Then change the permisions:

cp /usr/local/src/kamailio-4.2/kamailio/pkg/kamailio/deb/debian/kamailio.init /etc/init.d/kamailio
chmod 755 /etc/init.d/kamailio 

then edit the file updating the $DAEMON and $CFGFILE values:

DAEMON=/usr/local/sbin/kamailio
CFGFILE=/usr/local/etc/kamailio/kamailio.cfg

You need also setup a configuration file in the /etc/default/ directory. This file can be found at:

/usr/local/src/kamailio-4.2/kamailio/pkg/kamailio/deb/debian/kamailio.default

You need to rename the file to 'kamailio' after you've copied it. Then edit this file and set RUN_KAMAILIO=yes. Edit the other options at your convenience.

Create the directory for pid file:

mkdir -p /var/run/kamailio

Default setting is to run Kamailio as user “kamailio” and group “kamailio”. For that you need to create the user:

adduser --quiet --system --group --disabled-password \
        --shell /bin/false --gecos "Kamailio" \
        --home /var/run/kamailio kamailio

# set ownership to /var/run/kamailio
chown kamailio:kamailio /var/run/kamailio

Then you can start/stop Kamailio using the following commands:

 /etc/init.d/kamailio start
 /etc/init.d/kamailio stop

10. Ready to rock

Now everything is in place. You can start the VoIP service, creating new accounts and setting the phones.

A new account can be added using 'kamctl' tool via 'kamctl add <username> <password> <email>'. (or try without the email)

kamctl add test testpasswd test@mysipserver.com

If you are asked for SIP_DOMAIN environment variable do one of the following option.

 1.
 export SIP_DOMAIN=mysipserver.com

 2.
 edit '/root/.kamctlrc' and add:
 SIP_DOMAIN=mysipserver.com
