Ok, Ill do some work with ethereal in the ADSL router.

But I believe the problem is, when the calls go from the internet into 
the ADSL router, he doesnt know to wich of the NATed IPs he should 
deliver the call.

The outbound calls with Cisco phone already work, it just needed to have 
the public IP of the ADSL router  in the "NAT Adress". But... thats not 
a solution for ISP clients with dynamic IPs... dahm..

Why cant Cisco phones be smart as X-Lite?
