 My understanding is Siemens sells an optiPoint 420 and an optiPoint
420S. The 420S is the SIP version and if that's what you have you
should be able to obtain the firmware The non-SIP phones use Siemens
proprietary protocol which is based on an old version of H.323.

Perhaps its possbile to cross-flash the phones but I haven't found too
much clandestine documentation for the Siemens gear.

Recados,
