The FRITZ!Box DSL modem also connects telephones to an analog line. In such a setting, the nifty Frizzix can be used to receive call notifications on a Mac. All you need to do is install Growl and then run Frizzix. The following image shows a Growl notification being displayed in the lower right corner of the screen. Note that in this case, “Axel Rauschmayer” is the caller (as I’ve called myself with my cell phone).
