Software installation

As operating system we have choosen Debian Jessie, since all the software components we use provide packaging for it.

OpenSIPS

We got OpenSIPS installed via following commands:

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 049AD65B
echo "deb http://apt.opensips.org jessie 2.2-releases" >>/etc/apt/sources.list
apt-get update
apt-get install opensips opensips-json-module opensips-restclient-module

Once installed we proceed with loading the configuration out of specific tutorial cases bellow.
