Convert SIP Firmware to UNIStim Firmware

The IP Phone 1120E can be ordered with UNIStim Firmware installed or
with SIP Firmware installed. If you have an IP Phone 1120E with UNIStim
Firmware, and you convert the firmware from UNIStim to SIP, the UNIStim
Firmware is overwritten. To convert an IP Phone 1120E from SIP Firmware
to UNIStim Firmware, a firmware reload is required.

Action
Determine the appropriate UNIStim version to match the hardware
release number of your IP Phone 1120E.
There are different versions of UNIStim Firmware available for
download. Which version you choose depends on the hardware
release number of your particular IP Phone 1120E.
If the hardware release number of your IP Phone 1120E is among
the following hardware release numbers, download UNIStim
Firmware version release 0625C39 or higher (the hardware release
number is the Product Engineering Code (PEC) followed by the
release number):
• NTYS03ACE6 16
• NTYS03BCE6 16
• NTYS03BCGSE6 04
If the hardware release number of your IP Phone 1120E is not
among the previous list, download UNIStim version release 0625C23
or higher.
Note: UNIStim Firmware version names contain numbers and
letters. Use the last three characters in a version to determine
the minimum required version for the conversion. For example,
C39 is greater than C23.
