Convert SIP Firmware to UNIStim Firmware
The IP Phone 1140E can be ordered with UNIStim Firmware installed or
with SIP Firmware installed. If you have an IP Phone 1140E with UNIStim
Firmware, and you convert the firmware from UNIStim to SIP, the UNIStim
Firmware is overwritten. To convert an IP Phone 1140E from SIP Firmware
to UNIStim Firmware, a firmware reload is required.
Procedure 14
Reloading UNIStim Firmware
Step Action
1
Determine the appropriate UNIStim version to match the hardware
release number of your IP Phone 1140E.
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 1140E.
If the hardware release number of your IP Phone 1140E 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):
•
NTYS05ACE6 20
•
NTYS05BCE6 20
•
NTYS05BCGSE6 04
If the hardware release number of your IP Phone 1140E 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.
