Convert Unistim Firmware To Sip Firmware On The Ip Phone 1120E - Nortel 1120E Administration Manual

Convert UNIStim Firmware to SIP Firmware on the IP Phone 1120E

The IP Phone 1120E can be ordered with UNIStim Firmware installed or
with SIP Firmware installed. If an IP Phone 1120E is installed with UNIStim
Firmware, it runs with SIP Firmware only if the firmware is converted from
UNIStim to SIP. If the procedure to determine the UNIStim version number
is complete, and, if necessary, the procedure to upgrade the UNIStim
Firmware is complete, an IP Phone 1120E can be converted from UNIStim
Firmware to SIP Firmware.
Compare the version number to the minimum required UNIStim Firmware
version (0625C1H).
UNIStim Firmware version names contain numbers and letters. Use the
last three characters in a version to compare the version of UNIStim on
an IP Phone 1120E (0625C1H) with the minimum required version for the
upgrade. Note that C23 is greater than C1H and C1B is less than C1H.
The next procedure explains how to download the SIP Firmware from the
Nortel Web site.
