As you probably already know, the phones attempt registration to CM on TCP port 2000. Perhaps there's something in your CM list that would compel the phone to attempt registration to 0.0.1.1?

What are the fields for "Call Manager [1-5]" in your phone under Settings -> Network Configuration?

Regards,

Clay
