Phone Cannot Connect to Server

Problem
The IP addressing and routing fields may not be configured correctly.
Solution
You should verify the IP addressing and routing settings on the phone. If you are using DHCP, the DHCP
server should provide these values. If you have assigned a static IP address to the phone, you must enter these
values manually.
Phone Cannot Connect Using DNS
Problem
The DNS settings may be incorrect.
Solution
If you use DNS to access the TFTP server or Cisco Unified Communications Manager, you must ensure that
you specify a DNS server.
Cisco Unified Communications Manager and TFTP Services Are Not Running
Problem
If the Cisco Unified Communications Manager or TFTP services are not running, phones may not be able to
start up properly. In such a situation, it is likely that you are experiencing a systemwide failure, and other
phones and devices are unable to start up properly.
Solution
If the Cisco Unified Communications Manager service is not running, all devices on the network that rely on
it to make phone calls are affected. If the TFTP service is not running, many devices cannot start up successfully.
