what firmware should patch directly on the current, to have the latest


ftp 210.170.63.126/other/network1/Avaya/ERS5000/
I found firmware V6.3.5 it will be appropriate?

Firmware v6.3.5 isn't bad, but v6.3.6 is actually the latest.  It only came out a week ago, so not much testing has been done on it yet.
