Hi, check this:

The IP phone displays the "Host not found" error when the Services button is pressed.

Solution: Choose System > Enterprise Parameters. Check the URL services, and if it is set to the CallManager Server name, replace the CallManager Server name with the IP address as shown in this example.

Example: , where is the Cisco CallManager IP address.

Stop/start the TFTP, Internet Information Server (IIS), and Computer Telephony Integration (CTI) services and reboot the phones for the change to take affect.

For this good guide:


Hope this help
