Any firewalls/VPN's in between the pc and CUCM? Also, what do you see in the status messages on the phone?

Hi Will, excuse for late, but I was very busy to debugging the problem.
I've solved.
The problem was a mtu to high!!!!
The CUCM see the ipphone between a GRE Tunnel over a pppoe connection.
The ethernet mtu are 1492 and the pppoe support smallest mtu.
I've configured the tunnel mtu at 1375 and now all works well||| thanks for haelp
