Convert SIP Software to UNIStim Software
The IP Deskphone can be ordered with UNIStim software installed or with SIP Software
installed. If you have an IP Deskphone with UNIStim software, and you convert the software
from UNIStim to SIP, the UNIStim software is overwritten. To convert an IP Deskphone from
SIP Software to UNIStim software, a software reload is required.
Reloading UNIStim software
1. Determine the appropriate UNIStim version to match the hardware release number
of your IP Deskphone.
There are different versions of UNIStim software available for download. Which
version you choose depends on the hardware release number of your particular
IP Deskphone.
If the hardware release number of your IP Deskphone is among the following
hardware release numbers, download UNIStim software version release 062AC5L
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 Deskphone is not among the previous
list, download UNIStim version release 062AC5L or higher.
2. Download the appropriate UNIStim software file to your TFTP server.
3. Create an 12xxSIP.cfg file containing the following information:
