Ekiga 3.3.0 can be build with two trivial patches and newer PTlib (2.8.4) and Opal (3.8.4). This version work like a sharm without "unable to connect" etc. Reproducible: Always PTlib needs to be compiled with --enable-tts, otherwise opal failed with "undefined reference to `PFactoryLoader::PTextToSpeech_Festival_link()'"

Bump. Renamed the ebuild to 3.3.2, left the patches as they were, compiled and runs fine.
