Got my FX101 today, and it worked straight away (almost, there was a bug in 
the driver..).  You can sample the line on-hook, so a CID driver looks doable 
...  Howver I found out that there was no CID info being transmitted before 
the ring.

Guess what... BT actually charge a monthly rental fee (£1.50 or ~$2.40 per 
month) for providing this information.  Gotta love state monopolies hmm? Hope 
they don't take too long provisioning it...
