Thanks. Already looked through that collection.
Tried installing Gfax but straight away got bogged down in dependency hell!
Tried both the Java frontends but neither of them worked. In both cases the .jar files referred to in the ReadMe files didn’t appear to actually exist and the commands to invoke Java were wrong!
Is it really too much to expect a piece of software to actually come with a user interface? In this case even a basic text (input 'phone No., file name) one would be nice.
