The PJSIP Settings page provides configuration options for SIP-based devices and applications that use the UCX PJSIP channel driver. While a separate SIP Settings page exists for other SIP configurations, this page specifically supports deployments—such as NEC IP phones—that rely on PJSIP. Additional applications using this driver may be supported in the future.
To access this page on the UCX:
- From the PBX tab, select PBX Configuration
- From the left side column, select PJSIP Settings in the Settings group
NEC General Settings
The NEC General Settings in PJSIP Settings page is used to enable communication between NEC IP Phones and the UCX XSTIM software. The settings in this section control whether the UCX will listen for packets from the NEC phones, as well as which ethernet interface(s) will be listening, and what port the phones will be using for communication.
This section is used for configuring the UCX to support NEC IP phones using the default NEC SIP firmware. If you have converted NEC IP phones to use the "STD SIP" firmware then refer to the SIP Settings page for details; the settings on this page are not required.
NEC IP Phone Support
For security reasons the UCX does not listen for NEC IP phone traffic on any of it’s interfaces by default. If you wish to use NEC IP phones with the UCX you must begin by setting the NEC IP Phone Support.
- In the NEC General Settings section, navigate to the entry for NEC IP Phone Support
- Click the Enabled button
- If you intend to use the default settings for Bind Address and Bind Port, click the Submit Changes button; if not, proceed to the next section.
Bind Address
Once NEC IP Phone Support is enabled on the UCX, the UCX will begin to listen for packets from NEC phones on all its IP interfaces. Therefore, by default, this field is left blank. If you wish to limit the use of NEC phones to a specific UCX IP Address, then enter the specific UCX IP address you wish to use in the Bind Port field.
