If you are using DHCP, check the IP addresses distributed by your DHCP server.

If you are using DNS to refer to the TFTP server or to Cisco Unified CallManager,
you must ensure that you have specified a DNS server. Verify this setting by
pressing the Applications Menu button and selecting Settings > Network
Configuration > DNS Server 1. You should also verify that there is a CNAME
entry in the DNS server for the TFTP server and for the
Cisco Unified CallManager system.
You must also ensure that DNS is configured to do reverse look-ups.
Windows2000 is configured by default only to perform forward look-ups.
On the Cisco Unified IP Phone, press the Applications Menu button and select
Settings > Network Configuration > CallManager 1–5. The Cisco Unified IP
Phone attempts to open a TCP connection to all the Cisco Unified CallManager
servers that are part of the assigned Cisco Unified CallManager group. If none of
these options contain IP addresses or show Active or Standby, the phone is not
properly registered with Cisco Unified CallManager. See the
Phone with Cisco Unified CallManager" section on page 9-4
this problem.
If the Cisco Unified CallManager or TFTP services are not running, phones may
not be able to start up properly. However, in such a situation, it is likely that you
are experiencing a system-wide failure and that other phones and devices are
unable to start up properly.
If the Cisco Unified CallManager service is not running, all devices on the
network that rely on it to make phone calls will be affected. If the TFTP service
is not running, many devices will not be able to start up successfully.
