gcid4isdn package:
gcid4isdn is a GTK2.0 application that monitors incoming calls to isdn card and shows them via xosd. Currently it is in an early stage of development but functional and all help and ideas are welcome. See contact info. No RPM package for gcid4isdn yet but as soon as I fix some bugs and add some more features you can expect RPM.
