You need to install Debian Lenny (5.0) 64-bit on the server. A basic installation without any additional task selection (like Desktop System, Web Server etc.) is sufficient.

	Sipwise recommends using the Netinstall ISO as installation medium.

	If you use other kinds of installation media (e.g. provided by your hosting provider), prepare for some issues that might come up during installation. For example, you might be forced to manually resolve package dependencies in order to install the CE. Therefore, it is HIGHLY RECOMMENDED to use a clean Debian installation to simplify the installation process.

If you plan to install the CE on Virtual Hosting Providers like Dreamhost with their provided Debian installer, you might need to manually prepare the system for the NGCP installation, otherwise the installer will fail installing certain package versions required to function properly.

Using Dreamhost Virtual Private Server

A Dreamhost virtual server uses apt-pinning and installs specific versions of MySQL and apache, so you need to clean this up beforehand.

apt-get remove --purge mysql-common ndn-apache22
mv /etc/apt/preferences /etc/apt/preferences.bak
apt-get update
apt-get dist-upgrade

	Be aware that this step will break your web-based system administration provided by Dreamhost. Only do it if you are certain that you won’t need it.

The sip:provider CE is based on the Sipwise NGCP, so download and install the Sipwise NGCP installer package:

PKG=ngcp-installer-latest.deb
wget http://deb.sipwise.com/spce/${PKG}
dpkg -i ${PKG}

Run the installer as root user:

ngcp-installer

The installer will ask you to confirm that you want to start the installation. Read the given information carefully, and if you agree, proceed with y.

The installation process will take a couple of minutes, depending on your network connection and server performance. If everything goes well, the installer will (depending on the language you use), show something like this:

Installation finished. Thanks for choosing NGCP sip:provider Community Edition.

During the installation, you can watch the background processing by executing the following command on a separate console:

tail -f /tmp/ngcp-installer.log

You can download a Virtualbox image from here. Once you have downloaded the file you can import it to Virtualbox via its import utility.

The format of the image is ova. If you have virtualbox 3.x running, which not compatible with ova format, you need to extract the file with any tar compatible software and import the ovf file which is inside the archive.

On Linux, you can do it like this:

tar -xvf sip_provider_2.x_virtualbox.ova

On Windows, right-click on the ova file, choose Open with and select WinZIP or WinRAR or any other application able to extract tar archives. Extract the files to any place and import the resulting ovf file in virtualbox.

Considerations when using this virtual machine:

You can download a VMware image from here. Once you have downloaded the file you can just extract the folder inside the .tgz file and copy it to your virtual machines folder.

The format of the image is tgz. You need to extract the file with any tgz compatible software.

On Linux, you can do it like this:

tar -xvzf sip_provider_2.x_vmware.tgz

On Windows, if the file extension is not binded to any program, just right-click on the tgz file, choose Open with and select WinZIP or WinRAR or any other application able to extract tgz archives.
