Cisco CallManager and TFTP Services Are Not Running
If the Cisco CallManager or TFTP services are not running, phones might not be
able to start up properly. However, in such situations, 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 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.
To check that all services are running, use the following procedure.
Procedure
Step 1 From Cisco CallManager Administration, choose Application >
Cisco CallManager Serviceability.
Step 2 Choose Tools > Control Center.
Step 3 From the Servers column, choose the primary Cisco CallManager server.
The page displays the service names for the server that you chose, the status of
the services, and a service control panel to stop or start a service.
Step 4 If a service has stopped, click the Start button.
The Service Status symbol changes from a square to an arrow.
Note For more information about services, refer to Cisco CallManager Administration
Guide for more information.
