Download the appropriate UNIStim Firmware file to your TFTP

Create an 1120eSIP.cfg file containing the following information:

hardware release of your IP Phone 1120E, for example, 0625C23,
and yyy.bin is the filename containing the version number, for
example, 0625C23.bin.
Power the IP Phone 1120E off and on. The IP Phone 1120E reboots
and contacts the TFTP server upon bootup and downloads the new
UNIStim Firmware.
Enter requested information in the menu fields by pressing the number
keys on the dialpad. Press the asterisk (*) key to enter a period (.) when
entering an IP address.
To record the entry and advance the initialization to the next parameter,
