the load that displays on the phone.
If the phone has a static IP address, verify that
the default router is configured.

not provided a default router. Check the
DHCP server configuration.

the DNS server is configured.
If you are using DHCP, the DHCP server has
not provided a DNS server. Check the DHCP
server configuration.
The trust list is not configured on the Cisco

the phone in Cisco Unified Communications
Manager, and Apply was pressed so that the
changes take effect.
If you are using DHCP, verify that the DHCP
server is pointing to the correct TFTP server.
