ISDN monitor program showing busy channels in the system tray. Pops up a window showing the calling, called and redirecting numbers when a call comes in and displays a warning for expensive 0900 numbers. Also allows a d-channel trace into a file. Requires an AVM, Gerdes, or Scitel ISDN adapter due to the necessary CAPI 2.0 extensions.
