Our beloved softphone Twinkle hasn't been updated since 2009. Since the UI part was written in Qt 3, this great application gradually disappeared from (nearly?) all Linux distributions. There have been some quick and dirty ports to Qt 4, but these rely on Qt3Support which is gone with Qt 5. Hence it was needed to do a proper port. This is it.
