= 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. === Ekiga === Formerly known as Gnomemeeting, [http://www.gnomemeeting.org/ Ekiga] is a SIP compliant fully functional open source integrated VOIP and videoconferencing program. sudo apt-get install ekiga === Skype === [http://www.skype.com/ Skype] is a proprietary integrated VOIP and video conferencing program similar to Ekiga. *To get the most recent version, download and install the 32-bit version: wget -O skype-ubuntu-current_i386.deb <nowiki>http://www.skype.com/go/getskype-linux-beta-ubuntu-32</nowiki> sudo dpkg -i skype-ubuntu-current_i386.deb sudo rm skype-ubuntu-current_i386.deb ===== 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 <nowiki>http://www.skype.com/go/getskype-linux-beta-ubuntu-64</nowiki> 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: wget -O skype-ubuntu-current_i386.deb <nowiki>http://www.skype.com/go/getskype-linux-beta-ubuntu-32</nowiki> 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 "<nowiki>deb http://download.skype.com/linux/repos/debian/</nowiki> stable non-free" | sudo tee -a /etc/apt/sources.list > /dev/null sudo apt-get update sudo apt-get install skype === Wengophone === [http://www.wengophone.com/index.php/mp_download_wp_lin 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 [http://www.qutecom.org/ QuteCom], however. To install the current version as an Ubuntu/Kubuntu package, see [https://edge.launchpad.net/~cavedon/+archive/ppa these instructions]. *Download and install the older Wengophone Classic version (.deb package): wget <nowiki>http://download.wengo.com/wengophone/rc/wengophone-0.958m-1.i386.deb</nowiki> dpkg -i --force-architecture wengophone-0.958m-1.i386.deb === Gizmo5 === [http://www.gizmo5.com Gizmo5] is an Internet soft-phone application, similar to Skype, that uses the SIP protocol.

It is used for making VoIP calls from an Asterisk PBX. The current version must be installed from source files. See the website for download and installation instructions, or see [https://launchpad.net/ubuntu/jaunty/+package/kiax this Ubuntu Launchpad site]. === OpenSIPS / OpenSER (SIP server) === [http://www.opensips.org/ OpenSIPS] is an open-source [http://en.wikipedia.org/wiki/Session_Initiation_Protocol SIP] server that allows connections to be made through the Internet for [http://en.wikipedia.org/wiki/Voice_over_Internet_Protocol VoIP], [http://en.wikipedia.org/wiki/Instant_messaging IM], and other communications protocols. While there are many public SIP servers, these are subject to [http://en.wikipedia.org/wiki/Spoofing_attack 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 [http://packages.ubuntu.com/karmic/openser 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. === Web meetings === Web meeting software allows video conferencing among many clients, with one server as host. ==== BigBlueButton ==== [http://www.bigbluebutton.org/ BigBlueButton] is a free open source chat/video/audio and desktop sharing platform similar to GoToMeeting, WebEx, DimDim and similar products. Developed by GoogleCode, it utilises all open-source modules. A [http://www.dualcode.com/bigbluebutton/index.htm Moodle plugin] is also available.

Like GoToMeeting, free online group meetings for up to 20 users is available through any browser. A free open source host server for group meetings (unlimited users) is also available in an older community edition, but desktop sharing is not yet available for Linux desktops (in any edition). (Scheduling and recording to notes are also not available in the community edition, although the other enterprise features are). At this time, a .deb package for the host server is not yet available, and installation must be from [http://sourceforge.net/projects/dimdim/files/Dimdim%20v4.5%20Release/ source] (for which there are no instructions provided). However, a VMWare appliance for use within [[#VMWare|VMWare Player (or Server)]] is available [http://sourceforge.net/projects/dimdim/files/Dimdim%20v4.5%20Release/ here], and can be used after installing VMWare Player.
