If you are actually referring to phone firmware for the 3900's Nortel used to supply LW patchs that were installed on the PBX. It looks like from What I've seen lately on Nortel they have a server app that you can download to run on a server off of the PBX. Haven't done anything with it yet so don't know if it will require keycodes or not.
All this helps thanks. I basicly have a customer looking for M3902's Rels 5. We identif them by flash firmware version, if its a 80 to 90 we know its a Rls 3 to are customers. Is there a higher firmware version then 90. Like if you have a 5.0 and upgrage your phone what would be your firmware version?
