Background
NEC IP telephones configured on NEC systems such as the SV9100 or the SL2100 normally communicate with the NEC PBX with a non-standard SIP implementation to enable a high level of interaction between the PBX and phones to integrate the operation of the display, softkeys, button labels and presses and allow centralized control of each phone.
Normally, before NEC IP phones can be re-used on any other PBX (other than the UCX), they must all be converted to use standard SIP signalling. This process is intensive, requiring time and manpower investment to load new model-specific firmware on each phone, via a specially configured TFTP or HTTP server, boot the phone to a firmware update mode, flash it with the standard SIP firmware, configure the PBX server, user and password credentials and set the provisioning server URL to support feature programming on an individual phone basis, and then reboot the phone to verify the SIP registration with the PBX. At that point the overall level of functionality is reduced significantly to be more like the equivalent of an analog phone.
In contrast, when deploying NEC IP phones with the UCX, no change to any NEC phone is required. The UCX is able to use its XSTIM capabilities to provide enhanced operation of the display, softkeys, button labels and presses and allow centralized control of each phone . Furthermore, the NEC phones will no longer require user and password authentication, as the UCX simply associates each extension with the MAC address of the phone. In fact, if the NEC PBX is removed from the network and the UCX is re-assigned with the same IP address previously assigned to the NEC PBX, the phones will automatically connect to the UCX and register as XSTIM extensions.
