FritzCallerID is a SuperKaramba theme that shows number, name and address (if available) for incomming and outgoing calls.
It searches for the name and address for a certain number in the German phone book www.dasoertliche.de.
Phone numbers are fetched via the integrated callmonitor of the FritzBox, available on Port 1012. Before using it, you first have to open this Port of your FritzBox by dialing #96*5* from any connected phone. Firmware version xx.03.99 or newer is required.
It is still very experimental, no error handling.
