From turingart, branch of CUBiC:
F!Watch monitors AVM's FRITZ!Box Phone  DSL/VOIP devices and brings call histories right to your OS X desktop.
Since F!Box Phone is a central device in your network, you not even see your own phone calls, but all phone calls of all users of your VoIP, ISDN or analog phone lines. Since F!Watch polls your devices each few seconds, you always see the current call history in real-time.
Futhermore, F!Watch saves call histories as Microsoft Excel sheets. Thus, F!Watch allows to efficiently control your communication expenses.
