a call monitor for the FRITZ!Box, using a gmail address book and an area code directory

The FRITZ!Box family of routers also provide telephony services, actually all my phones go through my 7390. They are built using Linux and Busybox. On its TCP/IP port 1012 it offers event records on all telephony actions. Last Christmas I implemented a ruby script dealing with these event records and the “call threads“. Yes, there is even a notion of “call threads“. At that time I already decided I wanted to use my gmail address book as the data base for looking up all telephone numbers. Now I completed this task. There is a directory of area codes for Germany (“ONB“). I also make use of that one now: For every caller, whose telephone number is not listed in my gmail address book, I show at least from which area he called. I am rather glad with this software.
Initially I also wanted to make this ruby script an OS X cocoa ruby script with a colorful GUI, maybe to run on my iPhone. I’m not sure, whether I will ever be able to work on this.

Update 2010-07-02:
Having my script running now stably for quite a while, it was time for a new feature – somehow.
I have been using procmail for splitting my incoming e-mail for like 13 years or so now.
The procmail rules obviously derive from the addresses I am expecting e-mail messages from.
In former times I had a plug-in for emacs’s BBDB, that created raw procmail rules from my emacs address book.
Now with my new approach it makes sense to generate procmail rules from the gmail address book.
Tonight I was in the mood for an little programming excercise, and I implented this feature rather spontaneously. I like it very much.
Right …, generating procmail rules isn’t really a proper task for a call monitor, I do know that.

This software now makes use of an XML Gmail address book. If you want to find out more on this issue, filter this blog using the tags shown below!
