Videoconferencing and VOIP
Videoconferencing and voice over Internet (VOIP) applications are merging into integrated applications. Most of these applications now allow placing calls to non-Internet based telephones for a small fee.
Formerly known as Gnomemeeting, Ekiga is a SIP compliant fully functional open source integrated VOIP and videoconferencing program.

How to install Skype on a 64-bit system
The current version of Skype for 64-bit systems is a masqueraded 32-bit module. To use on a 64-bit system you might still need to install the needed packages:
sudo apt-get install ia32-libs lib32asound2 libqt4-core libqt4-gui
- Then download and install the current Skype .deb package from the Skype website:
wget -O skype_ubuntu-current_amd64.deb http://www.skype.com/go/getskype-linux-beta-ubuntu-64 sudo dpkg -i skype-ubuntu-current_amd64.deb sudo rm skype-ubuntu-current_amd64.deb
- If the 64-bit version doesn't work for you, use the 32-bit version (or see above for the most recent version):
wget -O skype-ubuntu-current_i386.deb http://www.skype.com/go/getskype-linux-beta-ubuntu-32 sudo dpkg -i --force-architecture skype-ubuntu-current_i386.deb sudo rm skype-ubuntu-current_i386.deb
Installing Skype repository
It is possible to install Skype by adding the repository and installing from there. This has an advantage of maintaining updates automatically.
- Install the respository security key. (This requires an open port 11371 in your firewall for the keyserver.)
sudo apt-key adv --keyserver pgp.mit.edu --recv-keys 0xd66b746e
- Add the Skype repository, update, and install Skype:
echo "deb http://download.skype.com/linux/repos/debian/ stable non-free" | sudo tee -a /etc/apt/sources.list > /dev/null sudo apt-get update sudo apt-get install skype
Wengophone is an integrated VOIP and videoconferencing client available on many platforms. Wengophone was initially an open-source GPL-licensed package ('Wengophone Classic'). Both the Classic version (available as a .deb file) and the current proprietary binary version are available from the website. Wengophone Classic has now been rebranded as QuteCom, however. To install the current version as an Ubuntu/Kubuntu package, see these instructions.
- Download and install the older Wengophone Classic version (.deb package):
wget http://download.wengo.com/wengophone/rc/wengophone-0.958m-1.i386.deb dpkg -i --force-architecture wengophone-0.958m-1.i386.deb
Gizmo5 is an Internet soft-phone application, similar to Skype, that uses the SIP protocol. Install (.deb package):

OpenSIPS / OpenSER (SIP server)
OpenSIPS is an open-source SIP server that allows connections to be made through the Internet for VoIP, IM, and other communications protocols. While there are many public SIP servers, these are subject to spoofing and other "impersonation" problems. A company may wish to host its own SIP server to avoid the problems inherent in public services whose trustworthiness can not be determined. OpenSIPS is the successor to OpenSER (which is the version in the repositories). Install OpenSER 1.3.2 from the repositories:
sudo apt-get install openser
Alternately, the newest version of OpenSIPS can be downloaded as a .deb package from the website and installed. Installation and usage instructions are on the website.
Telepathy is a flexible, modular communications framework that enables real-time VOIP/chat communication via pluggable protocol backends (for protocols such as Jabber/XMPP/Google Talk/Jingle, link-local XMPP, SIP, MSN, Yahoo/AIM and IRC).

sudo apt-get install telepathy-gnome
- A version for the KDE desktop (kde-telepathy) is available. For ongoing support see the KDE forums. Install:
