Manager; Tftp Server Settings; Ip Addressing And Routing; Cisco Callmanager And Tftp Services Are Not Running - Cisco 3905 Administration Manual

Troubleshooting and Maintenance
Phone Cannot Connect to TFTP Server or to Cisco Unified Communications Manager
Problem
If the network is down between the phone and either the TFTP server or Cisco Unified Communications
Manager, the phone cannot start up properly.
Solution
Ensure that the network is currently running.

TFTP Server Settings

Problem
The TFTP server settings may not be correct.
Solution
Check the TFTP settings. See

IP Addressing and Routing

Problem
The IP addressing and routing fields may not be correctly configured.
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. See

Cisco CallManager and TFTP Services Are Not Running

Problem
If the Cisco CallManager 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 CallManager 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. For more
