Have updated a 4.0.04c NAM with the redirect DN software and the nam will not see the phone system. have done this on another NAM with same results. have a couple of floppy that have the same dir on them after i unzipped the download and have use one in the past to upgrade at least 4 NAM with success. what are my options have reboot several times, never did get the two beeps to confirm software update. can i hook up a pc under hyper terminal and see anything as it boots. have one more NAM that is working that need to upgrade but am hesitate about the upgrade till i figure this out. have gone back to lower software on MICS and still no voicemail. these are fiber NAM and have verified the VM dn and called the station too but show not in service. Maintenance show empty MOD and have busy out and enable with no luck. this disk has several files on it, a read me file and the zip file but the new download of the upgrade matches my 2001 disk download that worked. any ideas please.
