Precaution
Correct programming of any system or application is, obviously, essential at any time, however. some
support issues have shown the effects that incorrect programming can cause in the specific areas where
an IP address is assigned to multiple devices.
It is essential that careful planning and deployment regarding IP addressing is performed to avoid the
many problems caused when there are IP address conflicts.
Please be aware that IP Duplication Groups should be programmed before the device(s) register to
the switch, never afterwards.
Please make sure that only the required SIP ports belong to IP Duplication Groups
Especially please do not change SIP timers unless advised by NEC Technical Support Department.
For example, changing PRG 10-33-01 (Registration Expiry Time) on the SV9100 is currently not necessary
or recommended for IP DECT as it is naturally set at the correct default for present purposes. Altering this
and some associated commands such as in PRG 84-20 (SIP Extension Basic Set Up) has been shown in
some cases to have serious consequences for customers IP DECT.
The defaults are;
PRG 10-33-01 (Registration Expiry Time) 3600
PRG 84-20-02/03/05/06 (SIP Extension Basic Set Up) 180
The correct methods of implementation for various systems and applications are covered in our relevant
training courses.
SIP Extension Registration
Before attempting to register any SIP extensions to the SV9100 check whether the SIP device requires IP
Duplication Allowed Mode set or not.
This is very important because if IP Duplication Allowed Mode is required it must be programmed before
the SIP device registers to the SV9100.
Please refer to the SIP Extension Features page for more information about IP Duplication Allowed Mode.
Enter the extension number for the SIP extension in Easy Edit–

The actual terminology used by the third-party device varies depending on the manufacturer.
The SV9100 uses port UDP/5070 for SIP Extension registrations. Most SIP Extensions use port UDP/5060
by default so this needs to be changed on the SIP device.
SIP Extension Authentication
The SV9100 can be set so that a SIP device is required to authenticate itself using a password before the
registration is complete. This option is Enabled by default.
Enable Authentication Mode by ticking the box in Easy Edit–
Extensions/SIP Device Setup
It is also required to enter a password per SIP extension using the Authentication Password option in Easy
