Cisco CallManager and TFTP Services Are Not Running
If the Cisco 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 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 are affected. If the TFTP service is not running, many devices cannot start up successfully.
To start a service, follow these steps:
Procedure
From Cisco Unified Communications Manager Administration, choose Cisco Unified Serviceability
Step 1
from the Navigation drop-down list and click Go.

Step 2

Step 3

service control panel to start or stop a service.
If a service has stopped, click the radio button and then click the Start button.
Step 4
The Service Status symbol changes from a square to an arrow.
A service must be activated before it can be started or stopped. To activate a service, choose Tools >
