Ekiga
Ekiga, formerly Gnomemeeting, is a free software for audio and video - telephony over packet-switched IP data networks for Unix-like (Linux, ... ) and Windows operating systems.
Functionality
It also allows conference calls, takes place by means Zeroconf other participants in local area networks, divides contact with evolution, forwards calls and are ongoing talks, it offers presence notification, performs an address book and call list and can penetrate using STUN NAT systems.
Technology
It supports a variety of audio and video codecs, among other common methods of leitungsvermittlenden fixed-line and mobile telephony, H.264, Theora, Speex and CELT. As a basic library for SIP and H.323 functionality Ekiga uses the free library OPAL.
Use
Ekiga was the default VoIP client of the popular Linux distribution Ubuntu, until it was replaced with version 10:04 of the operating system in October 2009 by Empathy.
History
Under the name Gnomemeeting the project by Damien Sandras as a master thesis at the Université catholique de Louvain in Belgium was initiated on 25 December 2000. Gnomemeeting based on the OpenH323 library and used the H.323 protocol for signaling. With this capability, other H.323 clients could ( such as Microsoft NetMeeting ) are either selected directly (via IP address) or by means of so-called gatekeeper be achieved as an intermediary.
For version 2.0, the name of Gnomemeeting was changed to Ekiga. This happened because the development has turned away more from a video - conference program in the direction of a multifunctional VoIP program and to indicate that Ekiga is not only meant for GNOME users. As the program has since then also about the popular for VoIP Telephony Session Initiation Protocol ( SIP), the similarities with the former model Netmeeting are only slight.
A Windows release since version 2.0.9 is publicly available as a beta - test version, meanwhile, but also as a release version on the page of Ekiga.
Version 3.0 brought massive changes. A broad-based internal modularization simplifies the development of alternative GUIs and implementation of other protocols, which is one of the bases for many of the desired characteristics of users.
Since version 3.2, the particularly low-latency audio compression method CELT is also supported.
