The "official" site is http://fcpd.berlios.de. It contains links to latest 
versions of our FCP protocol with some examples. Sadly their is not much more 
information available.

The communication with the FCP deamon should not be hard thing, because the 
protocol is quite simple. From my point of view the hardest part is to 
intercept SIP messages before they are forwarded, until you have received the 
confirmation of the FCP deamon that it will open a hole in the firewall, or 
reserved a port on the NAT box for media.

For questions about where and how to intercept and change the messages in the 
transaction management of SER Jiri is your man. I'll be glad to answer 
questions about the FCP deamon, or fix bugs (their are probably a lot).
