The IP Phone 1120E supports remote firmware upgrades through a TFTP
process and an automated UFTP process.
The method to upgrade the firmware depends on the following Call Server
software:
• For Succession Release 3.0 or CS 1000 Release 4.0, the TFTP
Server is required to download the current firmware. Enter the TFTP
Server IP address at the prompt.
• For CS 1000 Release 4.5 and later, use either a TFTP Server to
upgrade the firmware (at the prompt accept the default entry of
0.0.0.0), or UFTP to download the current firmware.
For further information about TFTP Server configuration, see
