The TFTP server stores configuration files for a phone that define parameters for
connecting to Cisco Unified CallManager. In general, any time that you make a
change in Cisco Unified CallManager that requires the phone to be reset, a change
occurs to the phone configuration file automatically.
Configuration files also contain information about the image load that the phone
should be running. If this image load differs from the one currently that is loaded
on a phone, the phone contacts the TFTP server to request the required .bin file.
A phone requests a configuration file whenever it resets and registers with Cisco
Unified CallManager.
