I have the same phones here (two of them). Got them directly from 3com
in late 2000 I think.

They were never distributed in the channel I think (at least not here
in Europe). Mine arrived "SIP ready", and I flashed them once with a
standard TFTP procedure. Unfortunatly, 3com discontinued them, no more
firmware are available, AFAIK. My firmware is SIP.

Unfortunatly I'm not able to find this latest firmware on file.

Note that the hardware is probably not the same as the standard NBX
phones : my SIP phones did feature an IR sensor to be used by a Palm
for automated dialing.
