Someone needs to create an xml file. Whether volunteers have to create a separate config for every state, or if it's possible to get away with a single config for the whole country, is something only the Americans themselves would know, I wouldn't know.

But as I've said before, it only takes one volunteer to create something that might work for every other American. Similarly for all other countries.

Also, in response to your other question: Though I generally don't answer questions that people could answer themselves by actually reading my first post, I'll repeat here that the program does not yet start automatically. Once it's installed, you must either come up with something to autostart it in the background (like how MohammadAG suggested), or just do it the way I recommend for testing: go to a terminal, type "callerid --daemon", and keep that terminal window open forever. The terminal will then show errors and diagnostic output when someone calls, kind of like a log.

I'll add something to autostart the program in the background once I'm sure the program is stable enough, and that the diagnostic output isn't needed anymore.
