A new major version of Ekiga has been released. The NEWS file has all the big changes since previous version and it's HUGE. One good news for you: SBo project has a SlackBuild for previous release (3.9.90) which can be used to compile Ekiga 4.0.0. All you need to do is to compile it's dependencies and probably update to the latest version of ptlib 2.10.9 and opal 3.10.9 before compiling Ekiga 4.0.0.
I have completed building Ekiga 4.0.0 on my desktop and it's working fine here. Anyone wanted to chat via VoIP? :)
