Our IMS clients will use DNS service to resolve which transport protocol to preferr and which server provides that SIP service. Therefore we need for this purpose working DNS server with valid delegated zones. In our case we are administrating own DNS zone named ims1.sip.uniza.sk. So we will add required resource records, first we add NAPTR records and then valid SRV and A records
So, prepare your DNS records, in our case:
Prepare five machines for your IMS, four of them with Debian Wheezy and one with Debian Squeezy. For all CSCF components and presence we will use Wheezy. The HSS will be installed on Debian Squeezy, because of better compatibilities with Fraunhofer HSS. All of them in our case are 32bit OSs.
Install the Key for this repository:
Find the according configs in the examples folder of Kamailio (Trunk) and copy them to configuration folder.
cd /usr/share/doc/kamailio/examples/pcscf gunzip kamailio.gz cp /usr/share/doc/kamailio/examples/PScscf/dispatcher.list /etc/kamailio/ cp kamailio.cfg /etc/kamailio/ cp pcscf.cfg /etc/kamailio/
Edit pcscf.cfg
MySQL Database installation
ICSCF need mysql database. During installation you will be asked for mysql root password, which will be needed in some next steps:
This HSS implementation uses as its backend MySQL database, so we need install mysql server also on this host. This step of installing mysql server you need to accomplish before installation of HSS, because HSS package executes post-installation scripts that creates HSS database with tables and users and this step needs functional and running mysql server.
During mysql installation you will be asked for mysql root password, which will be needed in some next steps:
Find the according configs in the examples folder of Kamailio (Trunk) and copy them to configuration folder.
