Having a hard time understanding what firmware a few of my m3904 phones are on. I've gone into load 32 and idu'd the TN's in question and I get release code 2 on one and 4 on another. I've also done the FWVU followed by the TN and got firmware version 89 on one and 92 on another. What firmware release are my phones on, and why couldn't Nortel just make things easier like they are on the Avaya Definity switches?
